Permetherin is highly toxic to cats, and unfortunately that's whats in a lot of dog collars, sprays, foggers and outdoor treatments, especially the over the counter crap.
Frontline has stopped working at all on fleas in my area. We switched to Trifexis, an all-in-one heart worm and flea medication that so far is effective, but unfortunately it costs a fortune.
I have ready about it, but was afraid that my cats or dog would breathe it in. I think it can harm them if they sniff it up. Although if you keep em out of the area and then vacuum I guess that would work.Has anyone used diatomaceous earth food carpet and furniture?
