Good morning. Today I was out to perform a one time service for yellow jackets. I inspected the interior, no signs of rear entrances in the drywall. I treated the entrance of the nest from the exterior with a liquid residual. Please be careful in the general area for a day or so as some activity may continue. Report any activity around the nest after several days. Checked the rest of the home, no other nests found.
