Thanks for your info on Sevandust risk. Sounds like it can be very dangerous if not careful. I have heard some of the same horror stories about Revolution and other Flea meds. I have always used Sevan sparingly on carpet only when there were actually fleas present. I usually put it on the carpet and then vacuumed. I'm sure that if this was used in a garden they used the sevan pump. This not only puts the dust on the plants but a lot would be put in the air to drift through fence and coat everything. Any insecticide, Frontline and house bombs included, can be dangerous if not used with caution. I had an Uncle that was an avid fox hunter and had 21 hound dogs. He used Sevan in his dog pens for years with no problems.

Precor however is not toxic and does work to break the flea cycle.
