Today I completed your one time service. I inspected all the areas of concern and found a breaching hole on the inside of the house. I used painters tape to seal the hole. I then applied a liquid residual application by the entry hole on the exterior of your home. This will help to eliminate the activity. I then knocked down a start of a wasp next that was by the front window. Avoid treated areas for the remainder of the day. Allow 10-14 days to see best results. Thank you for choosing green pest solutions!!!
