How Cedar Oil Kills Bugs

Cedarcide blog post image, how cedarwood oil kills bugs

In case our name didn’t give it away, cedarwood oil is the driving force behind our pest control products here at Cedarcide. So naturally, the obvious question is: How does it work? How does cedarwood oil (aka cedar oil) kill bugs? While the answer can get a bit technical, there are 6 basic ways cedarwood oil works to kill and repel pests like fleas, ticks, mosquitoes, ants, mites and more. Here’s a simple outline of each one.


Most bugs are extremely sensitive to moisture loss, which is bad news for bugs that come into contact with cedarwood oil. Cedarwood oil is extremely effective at leaching moisture from insects and other bugs, leaving them dried out and eventually dead.

It Disrupts Their Pheromones

Pheromones are chemicals that many bugs use for navigation, mating, searching for food, as well as to regulate bodily functions. Cedarwood oil disrupts these pheromones which not only disorients the insects but interferes with their fundamental bodily processes like breathing. The disorientation helps repel insects and other bugs, the interference with their bodily mechanisms kills them.

It Dissolves Them

Insects in earlier life stages-eggs, larvae, pupae-are extremely vulnerable, so vulnerable in fact that cedarwood oil can dissolve them on contact. In adult insects, arachnids and other bugs, cedarwood oil helps dissolve their exoskeleton. This allows the essential oil to penetrate their shell, hastening the oil’s pest control effects.


Emulsificationor the breakdown of fat particles, is another way that cedarwood oil works to control bugs. Like many organisms, bugs require fat to live. By helping disintegrate this fat into smaller, more fluid parts, cedarwood oil attacks bugs from the inside out.


As mentioned above, cedarwood oil can interfere with bugs’ capacity to breathe. Unlike mammals, bugs breathe through openings located on the surface of their bodies. When faced with the lethal effects of cedarwood oil, bugs attempt to limit their exposure by closing these openings, which prevents them from breathing. In other words, the bugs suffocate themselves.

It Messes With Their Body Chemistry

Like most every living thing, bugs must maintain a specific chemical balance to stay alive. Any drastic changes in this balance can have deadly results. Cedarwood oil neutralizes the acidity within bugs’ bodies, effectively throwing this balance out of whack. As a result they cannot properly function, and shortly die.

  1. Hi,

    What’s the shelf life of this product? Can I buy a 55 gallon drum of it and expect it to still be active in say….10 years from now?

    Also, how well does it work on fire ants and their hills?


    1. Jonathan At Cedarcide

      Great question, Bill.

      We guarantee our products for two years, but so long as you store them in a cool, dry place out of sunlight they will last you many years. For example, we have product here that we manufactured 10 or so years ago that the staff still personally use and it works just as before.

      For questions on purchasing a specific product in those quantities, give us a ring at 800-842-1464 πŸ™‚

    Question: How effective is your product with sewer roaches? Any suggestions? I usually use boric acid that dries them from the inside.

    1. Jonathan At Cedarcide

      Hi there!

      I would suggest our extra strength bug spray, Tickshield!

      I’m here if you need else or have questions πŸ™‚

  3. James Cassel

    This region is currently battling army worms. I’m currently using Cidercide PCO Concentrate (1 gallon) however, due to the damage I cannot tell if it is having an effect.
    I have about half a gallon of PCO concentrate remaining and wondered if I should spray with an increased amount and if I should saturate the grass. Any suggestions would be greatly appreciated.

    1. Jonathan At Cedarcide

      Great questions

      I would apply two more times, two weeks apart, at a dilution ration of 8 oz. in the Hose End Sprayer πŸ™‚

  4. I have a grass spider infestation that I’d like to get under control… reading this blog article and it talks about how the cedarwood oil will dissolve the exoskeleton/dehydrate/etc but it doesn’t say how long that process takes for adult spiders? Will it instantly kill the spiders after I’ve saturated the grass? Does it take a few days? Thank you in advance!

    1. Jonathan At Cedarcide

      Great question,

      In most cases for most bugs, our lawn sprays will kill in just a few seconds to a few minutes and then repel after that πŸ™‚

      I’m here if you need anything else.

  5. I recently bought a home on the Tx/NM border and am dealing with scorpions, roaches, and spiders. What is the difference in the Original vs the Scorpion treamtent? In previous questions you have recommended the original for scorpions, so I’m curious as to which one would most effectively treat all of them.

  6. so i use a power fogger/mister to spray your cedarcide pco. should i wear a mask to avoid breathing it in?

    1. Jonathan At Cedarcide

      Typically customers use the included Hose End Sprayer, which comes with it for free. You can also use a pump sprayer (1–2 oz. per gallon water), backpack sprayer (.5–1 oz. per gallon water), or a fogger, although foggers aren’t going to be the most effective application approach, you’ll end up losing quite a bit of the PCO to the air that way. No need to wear a mask.

      We’re here if you need anything else, Tony πŸ™‚

      1. Aiko Shimada

        Hello, In your reply you said “although foggers aren’t going to be the most effective application approach,” what would be a better approach than the fogger? Thank you.

        1. Jonathan At Cedarcide

          Hi there Aiko,

          For PCO Choice, we suggest a backpack sprayer, compression sprayer, or the Hose End Sprayer we include with the product πŸ™‚


          1. Aiko Shimada

            Thank you so much.

  7. Harry Crosby

    Okay based on what I have read in all the comments and answers Cedarcide might be a good deer repellent. I am testing this on on of my muscadine vines that they always much on this time of year. I sprayed the aphids and believe it kept the deer away too. The aphids died immediately btw. Have you done any test to see how deer like your product?

    1. Jonathan At Cedarcide

      Hi there!

      Nope, we do not have any testing for deer, rodents or reptiles, but our customers have claimed for many years that our products help with the last two, haven’t heard much regarding deer thought I’m afraid.

      We’re here if you need anything else πŸ™‚

  8. Was discussing Yellow Flies in my gardening group today. Someone reccomended using your product directly on themselves to repel these nasty biting flies. Wondering if there is a way to treat the yard or even just the front porch so we can enjoy these areas during yellow fly season? And how does this work? I’ve read all the comments, questions and answers and the general gist of things is that they must be sprayed directly to kill them. How does it repel them and for how long?

  9. LLOYD Bailey

    How long does a treatment normally last

    1. Jonathan At Cedarcide


      To clarify, are you asking about our outdoor products?


      1. What is the answer to how long does it last outside please

        1. Jonathan At Cedarcide

          Our lawn products should be applied monthly for basic bug prevention πŸ™‚

  10. Evonne Walsh

    Question: How will this effect flower and veggie gardens if sprayed near them? Is it effective against box elder bugs, ladybugs, Japanese beetles? Do I spray my entire yard (2 acres). Many thanks.

    1. Jonathan At Cedarcide

      Hi, Evonne!

      Our lawn products will not harm your flowers or veggies. We just advise that you not spray the veggies directly (cedarwood oil might be natural but it doesn’t taste that great).

      While we only have testing for fleas, ticks, mites, ants and mosquitoes, our customers report success using our products against almost all types of bugs. For best results, we suggest spraying your entire lawn monthly and broadcasting granules throughout your yard every 4–6 weeks πŸ™‚

  11. Laura Mazikowski

    Does this work for carpenter ants?

    1. Jonathan At Cedarcide

      Hi there, Laura!

      It sure does πŸ™‚

  12. What is the difference between the cedar and the lemongrass as far as efficiency against ticks?

    1. Jonathan At Cedarcide

      Hi, Jeanne!

      In our products, both the cedar and lemongrass products work equally well against ticks, although historically lemongrass is known to be especially effective against ticks. Personally, I use the Tickshield w/ Lemongrass whenever I venture into tick territory πŸ™‚

  13. katie william

    Hello, We have taxidermy that keeps getting fed on by beetles. We have pet dogs and birds in the house. What product would be safe to use that wouldn’t harm pets or damage the taxidermy? How would you use it and how often to reapply?

    1. Jonathan At Cedarcide

      Hi, Katie!

      Great question. Cedarcide Original is what you need. It’s safe for use directly on and around families, dogs, cats, and inside your home to kill and repel bugs. Protecting taxidermy with Cedarcide Original is a very popular use, many sporting good stores actually use this product to keep their taxidermy displays bug free. You would want to re-apply to the taxidermy monthly, or more often as needed.

      As far as your bird, we just wouldn’t recommend using the product in close proximity to him or her, as birds’ respiratory systems tend to very sensitive to essential oils, which are the driving force in our products. We’re here if you need anything else, just give us a call at 800-842-1464 πŸ™‚

    2. David W. Eastridge

      I also fog with cedar wood oil as a preventive …..but i dust all taxidermy with boric acid powder… Mahalo David

  14. Rhonda Myers

    Will this kill Carpet Beetles? Do I treat Baseboards and carpets,etc to kill them and larvae?

    1. Jonathan At Cedarcide

      Hi there! Our customers report great success using our products to kill carpet beetles. Spray them directly for a quick kill and protect vulnerable items and repel the beetles by spraying bedding, furniture, carpeting, rugs, and other fabrics weekly. Give us a call if you need any help getting rid of them πŸ™‚ 800-842-1464

  15. Hello. I am a new customer. I was wondering if the Cedarcide for in-home use would work against the common household roach?

    1. Jonathan At Cedarcide

      Hi there! It sure will. Cedarcide Original will do the trick, but it can take a few moments for the roach to fall completely dead. I’d recommend Original’s extra strength cousin Tickshield for a quicker kill. Here’s the link:

  16. Would cedarcide work on termites?

    1. Jonathan At Cedarcide

      In our experience and that of our customers, Cedarcide Original will kill them almost instantly with direct contact πŸ™‚

  17. James Murdock

    Can you send me the test data to support the claims you make, especially for backyard mosquito control?

    1. Jonathan At Cedarcide

      Of course, James! Email us at

      1. I would like to see the safety data sheet before I use Cedarcide as tick control for my dog. Can i send you my email? What if my dog licks it? Ticks are just coming out here in VT.

        1. Jonathan At Cedarcide

          Hi, Lee.

          To start, if your dog licks our products, there won’t be any issue. They’re non-toxic, plant-based, and pet and family-safe. Our customers have been using this product for over 20 years without issue πŸ™‚

          If you’re interested in an SDS, I’d suggest emailing He’ll set you up with what you need.

          Have an awesome day!

  18. Will it repel flies? Asking for my cows….

    1. Jonathan At Cedarcide

      It sure will! We use it at the Cedarcide Horse Rescue with great results. This is what you want:

  19. Will cedar oil kill earthworms? I have a lot of robins in my yard that eat worms.

    1. Jonathan At Cedarcide

      Hi, Joyce!

      Our products do not usually kill earthworms, no.

      1. Termites, in unfinished garage and outside. Any products that will kill? Thanks.

  20. Denis Byrne

    We get a cricket invasion into the house every fall plus have countless ticks and mosquitos. Is it effective against the crickets?

    1. Jonathan At Cedarcide

      Hi there!

      Although we only have testing for fleas, ticks, mites, and mosquitoes, in our customers’ experience our products work on almost any unwanted bug when sprayed directly πŸ™‚

      1. I don’t want to harm ladybugs or spiders. Does this harm them? That is terrible for a garden!

        1. Jonathan At Cedarcide

          Great question, Lisa!

          So long as you don’t spray them directly, they will be just fine πŸ™‚

  21. Zelma Williams

    Our area [Maine] is dealing with a huge outbreak of Brown Tail [moth] Caterpillars. They have toxic hairs that create a bad rash, potentially can be inhaled causing respiratory issues for some, and defoliate Oaks and fruit trees like crazy.
    We are in the caterpillar stage right now.
    Will the PCO Choice I use for ticks be of any use in killing or interupting this horrible insects??
    Thanks in advance!

    1. Jonathan At Cedarcide

      Hi, Zelma

      Yep! Our products can really help against those little monsters.

      1. Kathryn Ference

        Hi! I thought Cedarcide products were butterfly-safe.. how can something be both effective against caterpillars and also be safe for pollinators like bees and butterflies?

        1. Jonathan At Cedarcide

          Great question,

          It comes down to the life stage and how the product is applied. Our products are designed not to deter or prevent pollinators. However if you spray them directly with our lawn products, often the water alone can kill them, similarly if you spray caterpillars directly our products will harm them. Because pollinators are sight-driven and therefore do not exclusively navigate on pheromones alone, our products will not repel them from flowering plants they wish to pollinate. This is another reason we suggest applying our lawn products in the morning or evening, the window when pollinators are less. πŸ™‚


  22. Rosa Hsiung

    How often do I need to apply to my dog? Will I feel this spray on her coat? Will it feel greasy, sticky…?

    1. Jonathan At Cedarcide

      Hi, Rosa!

      For dogs that go outside often, daily or every other day. For mostly indoor dogs, every 3-4 days should do the trick. And nope, no greasy or sticky feeling, this product dries quickly and does not stain πŸ™‚

    2. What will happen to the chips when it rains will this stop them from repelling the bugs?

      1. Jonathan At Cedarcide

        Great question, Jessica!

        Nope not at all, unless they are washed away from your property. In fact, moisture can actually help increase their cedar scent, providing even more protection!

  23. Tips for successful removal of springtails? Indoor and out. Thanks!

    1. Jonathan At Cedarcide


      Simple solution for you: Cedarcide Original for indoors, and Lawn & Garden Kit for outdoors.


    How do you apply this to large long hair dogs? Must it cover all skin? Or just a spritz over all of dog? Same question for people. We too live in the woods and twice last week my three year old grand daughter came back in with a tick. How do I use the cedarcide on us people?

    1. Jonathan At Cedarcide

      Great questions,

      Here’s a video showing how to use Cedarcide Original on your dog:
      You simply spray all over, massage the solution into their coat, and use your hands to apply to their face,

      Cedarcide Original is also for use directly on people and indoors to kill and repel bugs. For yourself, you would just spray it all over like you would a traditional bug spray πŸ™‚

      1. Kimberly Shipp

        How does it smell?

        1. Jonathan At Cedarcide

          Hi, Kimberly

          It smells like a cedar closet, or a refreshing stroll in the woods. It’s very pleasant πŸ™‚

  25. I am fighting an mite infestation. If I use the fogger, will the residue afterwards affect my parrot? While I know Cedar Oil is toxic to birds, I’m unsure how fogging will affect him afterwards.

    1. Jonathan At Cedarcide

      Hi, Debbie!

      You would certainly want to remove the bird during the fogging. While you can return after 3-4 hours, we’d let the house air out for at about a day before reintroducing the parrot.

      1. Phil Spiesz

        I have a carpenter ant infestation in a ridge beam of my cabin. Can cedarcide stop them?

        1. Jonathan At Cedarcide

          Hi, Phil

          Cedarcide can absolutely stop them, try Cedarcide Original πŸ™‚

        2. Peter Douglas

          How does PCO yard spray affect beneficial insects such as dragonflies and honey bees?

          1. Jonathan At Cedarcide

            Great question, Peter!

            So long as you do not spray them directly, it will not harm or deter them. Glad to see you’re helping protect our pollintaing friends πŸ™‚

      2. Would like to use near my pond. Any adverse effects on pond or wildlife?

        1. Jonathan At Cedarcide

          Hi, Cheryl.

          Thankfully, our products are designed to be eco-friendly. We just suggest doing your best to avoid overspray into the pond, as cedarwood oil, our active ingredient, can be harmful to aquatic life at certain doses.

      3. Shirley Hoyle

        I use Cedarcide Yard guard and granular on my yard all the time. This is the first year I am growing tomatoes, peppers and squash in pots. I know you are not to water over the top of tomatoes, but can the granular cedar be put in the pots of vegetables just on top of the soil?

        1. Jonathan At Cedarcide


          Great question. Yes you can certainly use the Cedar Granules that way, both in indoor planters and outdoor, too.

  26. I feed many types of birds in the yard, with several feeders set up (I’m in NH), I’m concerned about the effect this product would have on them? I have turkeys that peck at the ground, birds on bird feeders knock seeds down, I have hummingbirds and squirrels, etc, Will these products hurt them if used around the yard?

    Also, I would love to rid my yard of ticks and mosquitoes but I have no desire to kill everything in the yard. I like the good bugs, spiders, dragonflies, monarch butterflies and all the others, etc., I also have frogs and toads that come through. Is is possible to effectively use your product(s) without harming the good ones? Thank you

    1. Jonathan At Cedarcide

      Great questions!

      We don’t like harming beneficial bugs and other creatures either. As long as you don’t spray them directly it will not harm any of these animals. However you are likely to see less spiders and reptiles given that they feed on many of the bugs our products will kill and repel. Let us know if we can be of any more help πŸ™‚

      1. Follow up to this.. will your product attract any unwanted bugs like wasps? I ask because I’ve used products that get rid of one bug but attract another. Hoping this won’t happen with this! Having a problem with spiders and ticks in my yard and want to try this out. Thanks!

        1. Jonathan At Cedarcide

          Hi, Sam!

          Nope! Our products will absolutely not attract any other bugs πŸ™‚

        2. Robyn Miller

          I have chickens that free range on my property. Is there any data supporting use around chickens, etc. or any precaution to ions Th at should be followed?

  27. Lynn Nguyen

    Hi! Will these harm my monarch butterflies and caterpillars? I have my milkweeds in a seperate area.

      1. Which product do you suggest to kill scorpions? I usually spray them directly when I can, but would putting granules out helpβ€”would they ingest them?

        1. Jonathan At Cedarcide

          Great question, Lynnda! This will show you exactly how to get the job done:

  28. We are having a bad elm seed bugs in Colorado. Would your product work on these bugs?

    1. Jonathan At Cedarcide

      Hi, Jenny!

      We have not tested for that pest specifically, but we have heard from customers that our products can help with these πŸ™‚

  29. how often would you recommend to re apply cedarcide to the lawns for ticks when dealing with rain season ?

    1. Jonathan At Cedarcide

      great question!

      Our lawn products, Yardsafe and PCO Choice, should be applied monthly for prevention and more often as needed for heavy, ongoing infestations. Rain does not usually cause any issue with the product unless it’s a very heavy rain that causes flooding or lots of standing water in your lawn, in which case you would need to apply again.

    2. Derek Wiles

      I have a an outdoor misting system that’s on a timer and was installed to help keep the mosquitos at bay.

      I’m looking for two things:

      1. The ratio of Cedar-wood Oil to water. ( 55 gallon plastic drum is used to store solution)

      2. Cost to ship Cedar-wood to zip 66062.

      Thank you!

    will the cleaning oils kill mites I am looking for something to clean out all my cabinets.Also do you have any thing with Cloves to clean ?this web site is amazing.would I have to wear a mask when I use cedarcide ?

    1. Jonathan At Cedarcide

      Hi Dorothy,

      Cedarcide Original is the product you want for killing mite. Cleanliness is vital to mite control so our cleaning products should help to some degree as well. And you would not need a mask to apply either of these products. We do not have any clove-based leaning products at this time, but we do carry close essential oil which you could use to mix up your own. Here’s the link:

  31. I have an imported wooden dresser that seems to have a wood beetle infestation. I can hear the clicking noises, but don’t see any sawdust. Would the cedar oil be something I could use on this piece and if so, how would this be done.

      Hi, Mary!

      Great question. Cedarcide Original is the product you want, and you would just need to find a way to apply it to them directly πŸ™‚

  32. I first learned of Cedarcide when I had a bedbug issue. Your site was very informative about how to get rid of them. Now I see no mention of bedbugs on your site. What’s up with that?

    1. Jonathan At Cedarcide

      Hi Michael! Nice observation! We’re currently updating our testing for bed bugs, and until that process is complete we’re not marketing for them at this time. If you need any help with bed bugs or have more questions, pls reach out to us at 800-842-1464 or email πŸ™‚

            I use cedarcide and love it for deterring bugs. Does the scent attract bears like cintranella scents?

            Hi James!

            It most certainly will not attract bears πŸ™‚

  33. Can any of your products be used in an organic vegetable garden? Every year I battle invasions of stink bugs and squash bugs.

    1. Jonathan At Cedarcide

      Hi, Carol!

      You sure can, but with one exception. We suggest spraying all around the plants, but not on any herbs or fruits you plan to eat directly. πŸ™‚

  34. Susan Thompson

    Do you have anything that will get rid of mice?

    1. Jonathan At Cedarcide

      Hi, Susan!

      At this point we do not, but I suggest checking out this article:

    2. Heather Hughes

      A cat!!! I have used Cedarcide for over 5 years now as very effective and healthier flea treatment alternative on my mice killers. Your local shelter more than likely has huge suppy.

      1. Agreed! Great answer! πŸ™‚

  35. Will cedarcide kill or repel cockroaches? Here in Florida we have some big ones. If so, does it need to be sprayed directly on them or would it deter them just to spray around the edges of the rooms?

    1. Jonathan At Cedarcide

      Hi, Margaret!

      Our products sure will! They do best to kill when applied directly, i’d suggest Tickshield or Cedarcide Original for that purpose. These products also work to repel when applied to common trouble spots and entry points weekly. Let us know if you need anything else πŸ™‚

  36. So, maybe you have heard that Pennsylvania is being overrun by a very bad bug called the Spotted Lantern Fly. It is not native to the US and is migrating west. It feeds on and kills hardwood trees and is very bad for the agricultural in the area including grapes in the many vineyards in the area. I have yet to see any on or around my property but I am hopefully that Cedarcide will kill the nasty buggers once they get here. Our department of Agg is looking for something that will stop their migration. Di you think your product will kill them or has anyone tried it on them?

    1. Jonathan At Cedarcide

      Hi! Great questions.

      We can’t say for sure since we haven’t tested on these pests, but our products are super great against flies when applied directly, so if we had to guess I bet our products will kill them outright within seconds. Applying PCO Choice monthly to possibly affected areas such as lawns and trees would likely repel them, too.

    2. Mary Beth

      Definitely kills spotted lantern fly. I live in PA. Didn’t see them until late last fall and they were everywhere. Cedarcide worked like a charm!!

  37. Sprayed Cedarcide along the bottom of my open window screen. Coming back later, I was shocked how many critters met their demise!

    1. Elizabeth

      Will this work on phorid flies aka scatter bugs aka coffin flies?

      1. Jonathan At Cedarcide

        Hi there!

        We haven’t tested on these flies specifically, but in our and our customers’ experience our products tend to kill most any type of fly when sprayed directly πŸ™‚

  38. I think your company and products are absolutely amazing. I am wondering about a couple of things: are you a public company? I have been investing in companies that are earth-friendly, and you seem like one. Also, what kind of cedar trees do you create your products from? Is it a sustainable practice? Again, I love your products, as they have changed how I take care of my yard and dog.

    1. Jonathan At Cedarcide

      Hi, David! Thanks for the comment.

      We are not a public company. We are a small, family-owned business but if that changes we’ll be sure to let you know πŸ™‚

      The trees we use for our products are called Juniperus ashei, and the practice is indeed sustainable, especially given that these trees are often considered weeds by many landowners

      1. Please be sure to let all of us know if your “not a public company” status changes!

        1. Jonathan At Cedarcide

          We sure will, Sue! πŸ™‚

  39. My dogs will sometimes eat grass. Will spraying the grass with cedarcide be harmful to them?

    1. Jonathan At Cedarcide

      Not at all! This is a non-toxic product, no need to worry πŸ™‚

        My neighbors have a honey bee hive. Will this harm their bees?

        1. Jonathan At Cedarcide

          Great question, Carol
          As long as you do not spray beneficial bugs like honeybees directly they should be just fine πŸ™‚

  40. I live in a house with a yard. I have 4 cats and two big dogs. I have been using your products for many yrs now. I do not give my animals any traditional products for fleas and ticks. I have in the past but finally took the plunge and decided to try for one full year with only using your products as well as some oils from a holistic vet for direct use on my dogs. I have no fleas or ticks in my yard my house or on my sweet pets. NO MORE POISON! No maquitos either! I love your products. Thank you! I also love your emails on so many helpful tips

    1. Jonathan At Cedarcide

      Thanks so much for the positive words, Christine! It means the world to us! πŸ™‚

    2. This sounds great Christine. What other products/oils do you use?

      1. Did the cedar oil bother your cats at all? I bought a gallon to spray all my rugs infested with carpet moths!
        I worry about my 2 cats.

        1. Jonathan At Cedarcide

          You will want to make sure you use a phenol-free Cedarwood Oil and that you formulate it specifically for pest control using appropriate levels of carrier oils. Our cedarwood-oil-based bug spray Cedarcide Original is safe for cats, dogs, families, carpeting, furniture, bedding and more. Here’s the link πŸ™‚

  41. Will cedarcide be effective against scorpions? We live in the Arizona desert and have problems with them in our home!

    1. Jonathan At Cedarcide

      It sure will! I’d suggest PCO Choice for outdoor and Cedarcide Original for indoor.

  42. How would this product, used in conjunction with your fogger, work on Indian Meal Moths specifically? Have there been any tests done in order to prove that it works if you say it does?

    I am not sure if you are familiar with Indian Meal Moths, but when they are in their larva stage, they hare highly destructive, chewing through plastic bags, like cereal, in order to feed and then pupate into the moth. While they are in larva stage, they look for tight place, like the inside of a jar lid that is still sealed, for example, and wedge themselves between the inside of the lid and outside of the jar. Thus, a spray wouldn’t work as effectively as a fogger I do not believe. Would this product leave a residual that would still kill an larvae crawling around before it can become a moth to lay more eggs, or would is still have to come in direct direct, like with a sprayer? As these creatures are very elusive and VERY difficult to find, spraying them directly just is not feasible in order to eradicate the problem.

    If it doesn’t work, that is fine, just found your product on Amazon and thought I would come over and at least ask the question since it does say Cedarwood oil would kill in the pupae and larval stages.

    Thank you.

    1. Jonathan At Cedarcide

      Hi, Kevin!

      We do not have testing for these pests in particular, however our products work great against moths in general. You’re rightβ€”fogging is going to be the best way to go after these bugs. Our products will kill on contact and deter thereafter, but not kill after application. However, if you fog, chances are you’ll kill most if not all in the first treatment, and then a second fogging would likely do the trick for good. Let us know if you need anything else πŸ™‚

    Fruits and vegetables ?

  44. Kristin Reese

    Will this help with cicadas?

  45. Carol Smith

    I live in the woods, literally. I use your cedar and lemongrass oil on my dog. Occasionally I find ticks on him but they are always dead and dried up. When Cedarcide kills the ticks on my dog I would definitely say your product is a wonder worker and recommend it wholeheartedly.

    1. Jonathan At Cedarcide

      Carol, thanks so much for the comment!

      We appreciate hearing the feedback πŸ™‚

    2. 2 Questions:
      1》 Can we safely spray PCO choice on our organically grown fruits and veg & if ok, how long before it is safe to eat or may we simply just wash off the product?

      2》 With free-range chickens & ducks I understand your cedar oil is not safe for them to ingest or to use on them. In using PCO Choice, if the birds were contained and the property then sprayed, would it be safe to let them free-roam the following day?

      1. Jonathan At Cedarcide

        Great questions, Carol!

        1). While our products are non-toxic and plant-based we do not suggest them for use on items intended for human consumption, simply just because we have not done testing for that.

        2). You’re right, it’s just never a good idea to use cedarwood oil in close proximity to birds. However, as long as you remove them from the area as you outlined above, all should be just fine πŸ™‚

        1. Chevy Cain

          I have four dogs and I have been trying to rid of their fleas here in California is flea season though my dogs are indoor dogs the yard is all concrete I water spray wash my yard daily and I spray their beds daily wash any bedding daily and since I’ve been using your product it seems they are scratching less my question is what do I use on the yard?? Plus I told my neighbors about your product too actually gave them some hoping it works for their dogs.

          1. Jonathan At Cedarcide

            Hi there! Thanks for sharing our product, we have no doubt it will work for their dogs, too. For your lawn I would suggest the Lawn & Garden Kit, here’s the link:

            Let us know if we can be of any more help πŸ™‚

  46. MJ Borner

    Is this good for carpenter bees?

    1. Jonathan At Cedarcide

      HI, MJ

      Our products will kill them on direct contact but not repel them after that.

  47. I have a huge Firefly population around my yard that we enjoy in the summer. Will cedarcide kill them as well?

    1. Jonathan At Cedarcide

      Great question!

      As long as you don’t spray them directly they will be just fine πŸ™‚

  48. I’ve recently noticed active wood boring beetles in a few furniture pieces. Which product can I use to treat the furniture and how? Do I also need to treat other pieces near by?

    1. Jonathan At Cedarcide


      Cedarcide Original would be a great contact killer for those pests πŸ™‚

    2. Margaret Brace

      Can you explain to me how you can spray your yard and get the spray only on the “bad” bugs? This is not feasible and is completely misleading.

      1. Jonathan At Cedarcide

        Of course, Margaret.

        We do no like harming our beneficial insect friends either. Typically beneficial insects like bees and butterflies are flying throughout your lawn, not just resting on the grass or soil, so they do not usually suffer any problems. As long as you do not spray them directly it should cause no issue for them. Spraying in the early morning is a great way to treat your lawn before the pollinators start making their rounds. Evening also works πŸ™‚

  49. We have used Cedarcide for 3 years now and WOW what a difference it has made. I have found only one tick on each dog in a year, which used to be weekly. This stuff really works and I am so relieved. No ticks, no more Lyme disease.
    Thanks Cedarcide!!!!

    1. Jonathan At Cedarcide

      Thanks so much for your encouraging words, Terri! You made our day, you rock!

  50. Barb Powell

    To be clear, can I apply this to prevent Japanese beetles?

    1. Jonathan At Cedarcide

      We’ve heard our outdoor sprays work great against these pests πŸ™‚

    2. Yes it does work—it reduced the population by half after one spraying

      1. Jonathan At Cedarcide

        Couldn’t have said it better ourselves πŸ™‚

        Thanks for chiming in, Susan!

  51. Does cedar oil kill all bugs – even beneficial ones?

    1. Jonathan At Cedarcide

      Great question, Trisha! As long as you don’t spray the beneficial insects directly, they’ll be just fine πŸ™‚

      1. We are fighting fleas on our five Yorkies. They get them from the yard and bring them in. Do I need to treat the yard. We do not have grass. Will it work, or just treat the dogs or dogs abd dirt?

        1. Jonathan At Cedarcide

          Yes, I would certainly suggest treating the yard. I would also suggest applying Cedarcide Original to the pups daily until the issue is resolved. Chances are fleas and eggs are also living in carpeting, pet spaces, and pet bedding, I would spray those areas with Original, too.

  52. Peggy Morris

    We have a large yard and flower gardens.
    1. Is it safe for the flowers and shrubs?
    2. How is it applied to a large area?

    1. Jonathan At Cedarcide

      Great questions, Peggy! PCO Choice would be my suggestion for spraying a large outdoor space. It’s plant-friendly, including flowers and shrubs. πŸ™‚ This video will show you how it works:

  53. Maggie Hammer

    Our horses get wood ticks. Can I use cedarcide on them?

    1. Jonathan At Cedarcide

      Maggie, yes, you certainly can! Cedarcide is great for horses. We use it out at our horse rescue all the time with great results πŸ™‚

  54. I’m glad to see this. When I first learned I had Lyme in 2017, I searched for a natural repellent.
    A lady in New England swore by cedar wood oil.
    I bought some. I use it,peppermint oil, and a spray I bought on a natural remedy site.
    What your article says bears out what I learned.
    Basically the ticks are totally fried. Works for me.

    1. Jonathan At Cedarcide

      Thanks for the comment and positive words, Jim!

      1. Harriet Janavey

        We have recently been invaded (about 1 or 2 a night )for the passed few weeks, by large dark brown moths that hang near the ceiling of our apartment bedroom. I have been using insecticide, but realize it is detrimental to our health. We live on the fourth floor, with a large evergreen in front of the window. I don’t know how these moths are getting in or if the tree could be harboring them? Would any of your Cedar produces help to eliminate these insects, and wherever they may be nesting? We welcome any suggestions.

        1. Jonathan At Cedarcide

          They sure will! Cedarcide Original will cover you for indoors, and our Lawn & Garden kit for outdoors πŸ™‚

  55. Where can I get this product?

    1. Jonathan At Cedarcide

      Hi! or via the phone at 800-842-1464 πŸ™‚

    2. Can I use PCO Choice to spray plants in a vegetable garden?

      1. Jonathan At Cedarcide

        Hi there! Yes, of course, you sure can. Just avoiding spraying any fruits & veggies directly. Cedarwood oil is natural but it doesn’t taste all that great πŸ™‚
