Is Tengard SFR really safe to use around cats?
I've read that permethrin is toxic to cats. Is this only if the product is used directly on them? Can they get sick by coming into contact with permethrin after it has dried? My concern is the cats (and dogs) will possibly get some on their paws and lick them, causing them to get sick. I'm also concerned if I spray the grass and they eat it. What is the difference between Tengard SFR and Permethrin SFR?
Most synthetic pyrethroids can be toxic to cats if they are applied directly to them or if they are allowed to walk on treated areas before they are dry. That being said, most cats do not have an issue being in a home that has been treated with a permethrin (as long as they stay out of the treated area until it is dry). Most treatments are limited to cracks and crevices indoors, limiting a pets exposure. Also, once the product has been diluted with water there is a very minute amount of the actual insecticide that will be available, usually just enough to kill a very tiny insect, not enough to have any effect what so ever on a mammal of any size. Permethrin used to cause a lot of problems when it was diluted with oil because the application would stay wet and available to the animals. In most cases today, the permethrin is diluted with water, which of course dries very quickly. Permethrin products are used in homes with cats everyday across the country.
