protective gear on. He was so casual. Never saw another wasp. It was a breeze though I felt bad at killing the little suckers.

Didn't touch the structure at all. I was ready to batten down the hatches. To the exterminator it was a big nothing. He went inside my attic I think to listen to where the nest was. I guess I was lucky. Good luck to you.

and no money for an exterminator. I bought some of that insecticide that shoots 30 feet and followed the instructions to do it at dusk, just as the light faded, and let the entry point have it. Within a week, the wall was quiet and I didn't see any more wasps.

Paper wasps built a nest under an eave outside a second floor window. I just waited until it got super cold, opened the window at dusk, and knocked it down with a broom. Either the frost had killed them or they'd decamped.

I love the desert. These problems are bad only next to the rivers.

Over an enclosed patio attached to the house proper. They had found their way in through a gap in the roofing materials, It's about a six inch high space and they had been at it a while.

When they started coming into the enclosed patio I realized I had to take action. I drilled a 1/8" hole in the ceilng below where I figured the wasps were nesting. Then I bent a little plastic tube 90 degrees, and attached it to a spray can of wasp insecticide. Inserted the tube into the hole in the ceiling, and I could tell from the angry buzzing up there that I had found the mark. In fact a couple of wasps escaped through another hole into the enclosed patio, obviously on their last gasp.

Then I stopped up the gap where they were entering from the outside.

No more wasp problems.

Oddly, I had seen them congregating in that area of the roof for a few months, but didn't realize they had created a nest inside the roof. Then again, I had lots of other work going on with the house.

One of these days I'll have to tear down the ceiling to remove the nest remains, as well as remedy any damage from a rainwater leak in an adjacent skylight.

The joys of home ownership, for a DIY'er.

use some mesh or nylons, hang them as close to the nest as possible, or toss them into the opening if you can. Keeps birds from nesting in the eaves also.
