Spraying your birds and or coop with one of these below isn't going to kill off all your bees, IMO.
Pyrethrin
Pyrethrin is an organic liquid concentrate derived form the flower Chrysanthemum Cinerariifolium, also known as mums. Mums are naturally resistant to pests thanks to the pyrethrin in their chemistry which is a natural neurotoxin. Pyrethrin
(MSDS) is considered to be a safe, low-toxicity pesticide that is easily inactivated in the mammalian or avian body, however it is highly toxic to insects, cats, fish and aquatic invertebrates.
Pyrethrin does not last long and
biodegrades quickly which is good for the environment. You can find this as an active ingredient of many mite and lice sprays found in retail stores.
Permethrin
Permethrin is the synthetic version of Pyrethrin. It does not degrade quickly like Pyrethrin, so it offers residual efficacy giving it more time to kill more bugs. In field and garden applications,
permethrin leaves residuals that wash into waterways and cause serious ecological issues, but this is not a major concern for us since we are spraying a small amount of it directly on our birds and coop, not over acres of farmland. Just like Pyrethrin, Permethrin
(MSDS) is a low-toxicity pesticide that is easily inactivated in the mammalian and avian body, however it is highly toxic to insects, cats, fish and aquatic invertebrates. This product is a common active ingredient in retail pest sprays and concentrates, it’s used in the Nix shampoo so many school children have used to rid themselves of lice and it’s on the World Health Organization’s list of essential medicines. Many military and hiking product companies treat uniforms, bug nets and other clothing items with this to guard against biting insects, especially in areas where malaria is prevalent. You can find different liquid concentrations of permethrin in farm stores and online.
