Today we completed a one time service for yellow jackets. It was good talking with you today. We found both yellow jackets, nests, and use an aerosol spray to quickly knock them down. We removed both nests and then treated the inside and outside of the liquid residual to helpprevent them from making another nest. This treatment can take up to two weeks to take full effect. I will definitely recommend after they die off getting rid of or washing everything that is in there. Contact us with questions or concerns. Thank you for choosing Green Pest Solutions .
