When I moved into my apartment in New York City, I was greeted with all sorts of pests including bed bugs, lice, roaches and fleas. I got Best because I have children and at the time was pregnant planning a home birth and I wanted a safe, organic way to treat my home and get rid of these nasty invaders. I've used Best for a year and it works! When I first got it, I was skeptical, but after finding a bug on my floor and spraying Best which killed it INSTANTLY, I was sold. This kit lasted me a year. I'm going to get a new kit and treat the whole apartment again like the first time since autumn brings bed bugs from other apartments in my building. Although the smell reminds me of the hamsters I had as a child, it is not offensive and even while pregnant it wasn't overpowering. I'm happy with this product and the service was great. Quick shipping.
