Hello! Today I was here for a long time service regarding wasps. There was an active bald faced hornets nest on the back screen door.I removed and discarded the nest and then treated the surrounding areas with a liquid residual product to deter returning foraging wasps.There is remaining nest residue on the screen, and the screen underneath the nest was a relatively large hole. However, the bulk of the nest, including the larva and core was fully removed. You may still see activity over the course of the next week as wasps return to their former nesting site. It is highly unlikely they will rebuild in the same location however, there is a 30 day guarantee so if you see any additional activity after approximately a week and a half to two weeks in that location, please contact the office.Thank you for choosing Green pest solutions and have a wonderful day!
