Fleadome Act’s proprietary formula is not only non-toxic and biodegradable, it performs unlike other traditional insecticides” as it does not effect the nervous system of insects, nor any other animal life. Fleadome Act works by suffocating insects. It is nano-technology. Its tiny particles enter the insect via “sphericals” (tubes) in the exoskeleton, and the insect breathes it in. Additionally, scientific evidence suggests that the formulation also acts as a protein degrader, and fleas have a protein base on their exoskeleton (as do mosquitoes).
