I am amazed at the response that we get when we begin our pest control program with people. They love to see dead bugs initially, and then not see them at all. We have given these applications the nickname “spider barriers” because people want to keep those pests out of their house, especially those spiders! Chemicals are sprayed around the exterior of your house and then acts as a barrier that the insects won’t cross, or at least cross very far.
