Good morning, it was nice meeting you today! I completed your service for bees. I used painters tape to seal up the areas around the bathroom light that yellow jackets were using to enter the home. I also taped over a wet spot on the ceiling that is likely from the nest. I used an aerosol to quickly knockdown any live yellow jackets on the interior. I then treated the entry hole to the nest from the exterior with a liquid residual. Please allow five to seven days for control. If you have any questions, concerns, or if you continue to see activity, please give us a call. Thank you for choosing Green Pest Solutions!
