It was a pleasure speaking with you today! Today I applied a liquid residual at the site of yellow jacket activity. We took every precaution in preventing chemical from entering the pond and we were successful in not getting any product passed the point we needed to treat. We will return in a week to check up on the yellow jackets and to pick up the web brush left behind. Please leave tarp attached if possible. If not, no worries. Please allow up to 10-14 days for optimal results. If you have any questions or concerns, please do not hesitate to contact us. Thank you for choosing Green Pest Solutions! If you were happy with today’s service, please leave a 5 star review!
