Today I completed your one time service for Yellowjackets. An aerosol was applied first under baseboards and in outlets in dining room where Yellowjackets have entered home. Then from the outside a liquid residual treatment was applied up underneath siding in rear corner of home outside dining room. As advised, please refrain from applying any store bought products on the outside of home. You can apply those aerosols on the inside if the bees appear again on the interior. Please allow up to 3-7 days to see a decrease in activity. Afterwards if after 10-14 days you are still seeing activity contact our office for a follow up. Thank you for choosing Green Pest Solutions and have a great day.
