How to repel wasps from building nests from a particular area?
My mom has an issue with wasps repeatedly building nests under an eave in her patio. She hoses the nest down but is too afraid to get up close to kill them afterwards, and by the next day they've started building another nest.
She wants to stop them from building nests on the house, but doesn't want to kill them if she doesn't have to. Ehow says that spraying the area with hot pepper is supposed to repel them, but she doesn't know when she can do this is they're always in the vicinity and repeatedly building nests.
The nest actually has to be removed and the area sprayed with insecticide or the wasps will always return and rebuild the nest. Spraying it with water won't help as it won't harm the nest.
Your mom could buy wasp insecticide and spray the area at night (a cool night is best) when the wasps are inactive. But IMO, it would be better to call a pest control company to do it. I had a huge problem with wasps last summer and the pest control company got rid of it with one visit.
The wasps can return and build a nest in another location, but it's probably too late in the season for this to happen. I've had a minor problem this summer in a different area than last summer.
Believe it or not, the "fake" wasp nests you can buy actually work as this fools them into believing the territory is already taken. I can't speak for the problem of rebuilding in the same spot though, as the spot has already been marked. That will need to be sprayed.
I once had a bee specialist come to get rid of a nest, think it might have been a ground one. He had to come back later, at dusk, to get the queen bee when she returned for the night (this happens every day apparently). He said if you don't get the queen, they will rebuild, led by her. Worked. IIRC, he did not kill her, but took them all away (he might have been a bee keeper?) We have since tried it ourselves, might have been a different kind of bee, we actually bombed the nest at dusk, and it has gotten queen also, I'm afraid we killed them. But you have to do it as the sun is setting or just after if you can still see or it will not work.
My theory on wasps is to KILL, KILL, KILL.
I'm terribly, horribly, awfully allergic to them though. That may inform my opinion somewhat. You do need to get the nest down, clean, and spray.
I'd call an exterminator.
We have one of the fake wasp nests and I'm not convinced it is doing a lot of good -- though I haven't seen much in the way of wasps nests being built this year in general. Wasps were flying around and annoying us last week during an outside dinner.

I had a wasp problem this summer, they kept building a nest on our home one was on the eave right above my front door. Very scary, specially with the 4 kiddies. The nest was taken down at night and then we sprayed it with ecosmart wasp spray. No problem ever since. Good luck!
