Jeffery from Athens, Pa writes
I sprayed flea spray with Permethrin SFR 36.8% in it in one side of the basement. Not very close to the furnace. But I started to worry.
The Label states that Permethrin SFR 36.8% is safe for indoor use. Once the product dries, and as long as you didn't spray the furnace directly, it is safe.
