Hornets have built a large nest in the wall of my inlaws home. They have actually chewed through the sheet rock and were getting in the home. We have covered the area with plastic and duct tape. We pull it back to shoot wasp and hornet killer in. We have found where they were getting in and have sprayed the area and caulked it. They persist. The size of the nest can be seen by a large 2′ by 1′ grey area showing through the sheet rock. Any ideas? Fogger? Professional?
Thanks,
EJ
