Winnetka Wall-Void Yellow-Jacket Treatment at an Exterior Entry Point
·

Problem Summary
My Pest Crew found yellow-jacket activity concentrated at a small exterior opening leading into a wall void. Because the nest was concealed inside the structure, the service centered on the active entry point rather than removal of an exposed nest.
What We Did
The active opening was treated to reach the concealed activity inside the wall void. The serviced opening was then closed with copper mesh at the end of the visit.
The rest of the exterior was also inspected, and no other active yellow-jacket areas were found. The copper-mesh closure was part of the pest-control work and was not a permanent structural repair.

Results
The serviced wall corner was treated and closed during the visit, and no additional service was needed afterward.
