Hello. Today I completed your one time service for bees. I found the entry point by the kitchen window, where the yellow jackets are entering the siding. I checked the kitchen area and basement for possible breach points and found none at this time. Keep an eye for discoloration or softening of the drywall as they may try to breach. If that is to happen, reinforce that area with painters tape to prevent entry. I treated the entry point with a non-repellent liquid solution, targeting yellow jackets. Please allow five days for the treatment to take full effect. If you’re still seeing activity after five days or if you have any questions or concerns, please contact customer service for a follow up visit. Thank you for choosing Greenpest solutions.
