Good morning. Today I completed your one time service call for yellow jacket activity. Today I used a liquid residual product on the exterior eaves above the garage as well as the exterior eaves of the front of the house and treated for yellow jacket activity. While the product drys and while the yellow jackets fly in and around the treated areas, they will teach the chemical onto their bodies essentially killing themselves off in a matter of 3-5 days time and thereafter you SHOULD start to see a decrease in the yellow jacket activity in both areas. If you should have any questions or concerns please call us. Thank you for choosing Green Pest Solutions.P.S. Agreement signed by customer online at time of service and credit card payment info taken at time of service.
