While exterior only treatments can help reduce the number of pests on your property, it should not be used as the only solution. There are many entry points for pests, which can include the attic, basement, windows, doors, and/or crawlspaces. Exterior only treatments create a barrier of 3 feet up and around 10 feet out from the foundation of the structure(s) and will not deter/terminate pests gaining entry from a higher elevation. Sometimes you will need crack and crevice treatments on the interior of the home for strategic placement of product to help with any pests that have made it to the interior of the house. We are always happy to inspect the interior of the house to see what issues exist and share our plan of action with you based on what we find.
