The policies above can be shaped to PH needs at the county or state level according to human host, vertebrate reservoir, and sand fly and triatomid interactions. The epidemiology or the revelation of disease transmission depends on learning the reservoir hosts, especially ones like dogs and cats, and the insect vectors as well as the life cycles of these protozoan parasites. To stop transmission requires: a) determination and b) technical supplementation.

The insecticides sprayed or used as fumigants are most effective against household triatomids include lambdacyhalothrin, then alfa-cypermethrin, cyfluthrin and deltamethrin. Insecticides and methods of application must vary considerably according to the vector and also the community ecology like savana or woods.
