Bifen I/T is a synthetic pyrethroid class insecticide. It kills crawling insects. It is very low odor and does not work by inhalation. The issue with the bird is in my opinion again, something else. Even if Bifen I/T were sprayed indoors, around and near the bird, the bird would not bleed. Bifen I/T is not an anticoagulant and does not work this way.
If you read enough posts about pesticides on the internet, you will panic and think that the end of the world is near. I can tell you that after being in this business for over 40 years, the claims against most pesticides being dangerous and life threatening - in my opinion - are greatly exaggerated. Bifen I/T by its very nature would have a limited impact on the surrounding environment. It probably won't have much impact on the Mosquitoes either.
Hope this helps.
