Good afternoon. Today I completed your one time service for yellow jackets. I applied a liquid treatment to the void that the yellow jackets were flying in and out of on the right side of the home. Please avoid the area for a few days. The yellow jackets are agitated and will sting. I didn’t find any 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 day!
