Exclusion. Have you heard the term? Do you know what it means? Well, the golden age of Pesticides is behind us. Pest companies no longer come to your house and douse everything--including your bed--in a heavy coating of pesticides. Though this method was highly effective at killing bugs, it did a pretty good job of making humans sick too. In this modern day, pest control companies rely on a worldwide database of pest information to "exclude" pests from your home. Think of exclusion as a sort of cold shoulder. If we were talking about a human pest, exclusion would come in the form of, perhaps, not answering the door, not returning a phone call, or putting a lock on the door.
