Good afternoon. Today I completed your one time service for yellow jackets. Your husband showed me in the corner of the front porch of yellow jackets flying in and out of the wall. I applied a liquid treatment to the entry point. Please avoid the area for a few days. The yellow jackets are agitated and will sting. No other nesting at this time. If you still see activity after 7-10 days please give the office a call to have us come back for a retreat. Please allow 10 to 14 days for our products to take effect. Thank you for choosing green pest solutions.
