Wasp Nest - What To Do?

Seems that we have a wasps nest under the eaves. The loft space behind it is inaccessible (both in terms of wasps getting into the house and for anyone getting under the eaves to dispose of the nest)...

Read some differing opinions so hopefully looking for some real life experience of similar situations on here.

Seems that the nests become inactive in autumn and the wasps never return to a nest (we've not even noticed the nest until Friday when the window cleaner flagged it to us!). So given they're not causing any grief, is it ok to leave until it becomes inactive? If we were to remove it, I don't see how it could be accessed without lifting tiles as theres no access from inside the house. Or would the exterminator just climb a ladder and basically gas the nest from the outside?

Any advice appreciated!

Leave it. They’ll all be dead in a month. You’re right that they don’t go back to an old nest, but they can build a new one nearby. Over winter I’d suggest blocking off the entry point if possible, although there is probably another way in there.

If it isn’t bothering you then I wouldn’t be too worried overall. If you block off access, they might build somewhere that does bother you. In any case getting rid is easy. After the sun has set, just get some powder near the entrance and they’ll be dead in no time.

Had exactly the same a few months ago, wasp man gassed it from the outside.

I had one in the same position - a large flat nest between the tiles and the roof felt.

As with you it was not a nuisance so I left it and I cleared it out the following year by lifting the tiles.

I found that they had chewed and damaged a lot of the felt and some of the rafter wood - so I'd suggest getting a pest controller to kill it now.

I think they squirt wasp killer fluid/foam in with a long tube.

We have had multiple nests over the years ( old inviting house downsides ) and the last one was when we had some painting of the outside being done - hadn't really noticed until then.In the eaves as yours , local chap arrived long powder spray ,waited 5 minutes and repeated , job done.

I had simular and was able to spray wasp powder around the gutter/eaves. The powder comes in a puff bottle so you don't have to get too close. The wasps then track the powder into the nest and it kills everything inside. Obviously the empty nest still remains

I noticed a nest in our wall earlier in the summer, but left it as they weren't bothering anyone, but a few months later it was much bigger - the local bee keeper came and puffed some powder into the nest. He thought that from how many wasps were outside there would be in excess of 3,000 wasps inside the nest.

The powder didn't work fully, and he had to come back a week later, and used some foam, which seems to have done the trick. We are still getting the odd wasp in the room nearest to where the nest was, I don't think they are finding a way in through the wall, but can't be sure.

OK, thanks all. I'll give a pest controller a call - they're not bothering me but I don't want there to be damage to the roof etc and if they can do something thats pretty inobtrusive, that works...

In terms of any damage they are going to do, they will have already done it. The nest is winding down now, the queen is on her last legs.

We had 3 treated this year and another one we couldn't work out exactly where it was. The main reason for treating was because some of them were getting into the house via the attic, and because we couldn't work out which nest was responsible we had all of them treated.

Year before we had none, but normally we get a couple of nests per year in some part of the house.

Wasp foam sprays have quite a long range, so can sometimes deal with nests in tight spaces.

Otherwise ant powder puffed round the entrance to the nest will usually deal with it.

I usually get 1-3 nests per year, I bought some powder off eBay and made a contraption using an extending pole (painters), some plastic tubing and then attaching the bottle of powder to one end and inserting the other end into the offending gap and flooding the space with as much of the powder as I can.

It's worked so far and wasn't too expensive to buy the bits.

I also have a few of the hanging containers in the garden and the solution in them which attracts them and that usually gathers hundreds over a few days.

This year I managed to kill two queens early doors before they had time to get the nests going and had none this year.

Lots of advice on how to get rid of them. However what are wasps actually useful for? Is there any reason to be grateful for having wasps?

They're pollinators. They eat flies, aphids etc.

At this time of year, just let them be unless they're actively causing a problem.

I think they keep aphid and greenfly numbers down.

Had a few nests over the years and provided they don't become a problem I tend to let them be but a couple of years back I was rewiring the lighting in my garage and found a massive nest right where I needed to run a cable and they weren't happy with me crawling around in the loft space (I didn't have an alternative route so they needed to go!!!)

Bees make honey; wasps make Marmite.

So it depends if you like marmite.
