How do I find where pests are getting into my house?
Pests often bypass exterior treatments by slipping through hidden gaps that are difficult to locate visually, leaving residents trapped upstairs in fear of a sudden encounter. Without knowing the exact point of entry, homeowners cannot seal them out effectively, which keeps the infestation active inside main living areas and bathrooms.
