The Federal EPA has consistently limited the use of known toxicants (insecticides) to preclude their admixture into paints and coatings by contractors or homeowners for the purpose of repelling or killing insects on the dried or cured coating. The current invention utilizes materials taken from the EPA's GRAS (Generally Recognized as Safe) List for this purpose. Furthermore, the current invention utilizes the insect repellant nature of these materials to repel insects from the area during coating application, thereby eliminating the need for topical insect repellants such as DEET.
