A basic service includes a full interior spray along with an exterior service to all landscaped areas of the yard. Most areas of treatment will be sprayed with a liquid chemical that leaves a residue which the bugs come in contact with and die or are repelled from the area. This process is not a miracle or magic—it does take time and you will see some bugs as the process is carried out. After an initial service it is very common to notice more bugs for the first week after the treatment due to the fact that they are sick and aren’t concerned with being concealed for protection.
