Today we completed a one time service for yellow jackets. It was great talking with you today. We treated the exterior entry point of the yellow jackets nest with the liquid residual to help slowly kill the nest. We also use an aerosol spray in the inside where that they were building a nest. We also put tape over their exit points. They stopped getting into your house. Give this treatment up to two weeks to take full effect. Contact us with questions or concerns.
