G.P.C. provides an initial interior clean-out of your home to exterminate all pest/bug invaders. After the inside clean-out, we then focus on the exterior barrier treatment of the home to eliminate the pests/bugs on the outside where they breed and live. The initial inside service includes treating all cracks and crevices and electrical switch plates in key areas such as bathrooms, kitchens, and common areas within the home. If necessary, the attic may need to be fogged or dusted. This would be in the case of an existing infestation.
