Nope! Interior treatments are included in the price for all IPP members. Interior treatments are not effective in keeping new insects from entering the home. That is why exterior treatments will always be the more effective treatment. Interior treatments only help exterminate the population of insects that are inside while the exterior treatment helps with exterminating both. The product used inside will stay effective for a longer period because it will not be battling any of the outdoor elements. We recommend if a home needs an interior treatment one treatment a year is all you need.
