Good morning. Today I completed your one time service for yellow jackets. Upon arrival your wife showed me the void above the garage that the yellow jackets were flying in and out of. I applied a liquid residual treatment to the nest. Please avoid the area for a few days. The yellow jackets are agitated and will sting. There were no other nests at this time. Please allow 10 to 14 days for our products to take effect. Thank you for choosing green pest solutions. Have a great weekend!
