Chuckle if you will. They don't have the same bottle look as I used, but the lice control for canaries and parakeets worked great!! No holding eggs back, I sprayed it on legs, back and front of neck, behind, back underwings..wherever I saw them or just decided to treat if I saw them in one place.
Most folks use permethrin/garden dust. Kills them dead and extremely cheaper. The chickens and the coop have to be done again in 7-10 days to kill any eggs left behind though.
