A perimeter treatment with a residual pesticide at the soffit and fascia area will get most of them. Typically they don't nest in structures but usually in trees and shrubs in paper cone type nests. Brown wasps and yellow jackets do nest in structures and home a lot.
ooops….guess I wasn't clear: they're about 7 feet high in a rhododendron bush right next to my little trapping shed. nest is about the size of a cantaloupe.
Safest is wait for a cool morning, early, and get them in the nest and too cold to fly. Step ladder with Raid wasp and hornet, as the residual kills and I think they have ether in the mix so it stuns them, so they do not have the opportunity to get mad and sting.
been avoiding the area, and of course the lawn was getting out of control. so, I watched the nest for like 5 minutes and saw no activity. got out the hornet spray and dowsed the nest, and nothing came out.
It is near the end of the season for them. Probably all the larvae have been hatched for the year and flown off. They will usually abandon the nest this time of year if they planned their season correctly. Some miscalculate and hold on too long and many will freeze out if they don't head to structure for the winter.
Everybody has something they dont willingly do. For me, I hate rats. My coworker, snakes.
I am impartial to dead possums that have to be removed from the belly of trailer homes...especially when the customer waited three weeks because they thought the smell would go away on its own.
