Wasp nest in a/c unit, how would you deal with it?

[White_Knight_II]

I was up on the roof of the fifth wheel cleaning today and found a wasp nest approximately one foot in diameter, mostly inside the cover. I've dealt with nests underneath, where a person can spray the nest, and run like heck, and repeat until all are dead. I'm pretty sure I don't want to try that on the roof. I might wait until freezeup and take care of it once they go into hibernation. Any suggestions?

If you can get a Shop vac hose close to the entrance put an inch of water in the shop vac and a bit of dish detergent. Let it run for an hour. You will have most of them doing the backstroke in the shop vac. Then blast away.

Tape down the hose.

Drive to Alaska they should die pretty quick. Good road trip excuse.

Sevin powder. Dust it liberally in and around the entrance to the nest--a plastic ketchup bottle works well--and the wasps will be dead in a couple of days. The advantage is that, unlike the sprays, it does not enrage the wasps, they just go on about their business, tracking the Sevin in to the nest where it kills them all.

I deal with bees nest all summer. Spray it and walk away. No need to run if you soak it thoroughly.
