I have discovered that wasps are getting into a cavity on the front of my house. It's where the porch has just eased a short distance away from the wall. I have tried squirting in there with Zero in Ultra Power wasp and Fly Killer from Screwfix, but it doesn't seem to have done anything.

Any suggestions, please?

Keep going with the spray, or what?

I’ve got the same problem in our roof. I’ve used the foam version of their wasp killer which expands once sprayed into the gap.

They exit close to the vent for my son’s en suite shower and we’re still getting a few coming in, so another dose might be needed.

I got stung earlier in the week whilst walking the dog so I have it in for them the little bds!

Call in the famous Scottish wasp killer, Phil Macavity?

(wait until nighttime and fill the gap they’re using?)

You can get stuff to spray into their nest, or powder to put into the entrance, if that’s practical, but it’s possible the nest is somewhere in the void they’re crawling into.

We had a nest a few years ago in our wall cavity. The guy we talked too said if they are not bothering you the queen will fly the nest taking her brood with around late September which true to his word they did.

He said once they vacate a nest it will stay empty and they have never returned.

I have seen them build new nests on top of old ones.

Around September the queen does look to hibernate and the rest of the colony just dies off.

What kind of wasps are they? Some are completly harmless except when they are eating the parasites in your garden.

We seem to have an inherent desire to kill all wasps for some reason, perhaps we fear them as a child?
Wasps are vital insects in the garden, just a shame they are a 'warning' yellow colour and can sting.

Unless they are causing a real nuisance could you leave them be, and then block off access after they have vacated which should be anytime now?
Their nests are amazing structures, when we have had them nest my lad would take the nests into school when he was little for 'show & tell'.

There are bees that look almost identical to wasps so please be sure they are wasps if you are destroying them.

Wasp on left, bee on right...

Therefore, patience for a few weeks and they will go? But, will they return? I suppose I could seal the cavity with foam after they've gone?

My dad used to sit in his garden with a blob of jam on his finger feeding them.
Fascinating little things when you spend some time watching them work.
Interesting how they clear dead bugs of the front of cars.

The only good thing about having a wasps nest is that the queen will never build a new one in the same place.

I use a puffer with ant powder to sort them out.

If that isn't practical it's best to "get a man in" with proper equipment to do the job.

I was on holiday last week and a few kept harassing us on the patio of where we were staying every time we took a glass of beer or some food out. There was a shrub close by which the bees and wasps love (Cantoniaster). Is there any way to humanely dissuade them in these circumstances?

I am not averse to them in general, but fishing them out of your beer is a pain, and having to be careful you don't trap them in clothing etc and get stung accidentally was getting frustrating.

Yesterday morning I had a dragonfly in a right tizzy on the ground outside the back door. I couldn't understand what was going on but then spotted a small wasp on it's thorax just behind its head. The dragonfly couldn't shift it. I can't imagine a wasp attacking a dragonfly and don't even know if they have a useful sting. I poured some water on them and the wasp walked off. I put the dragonfly in a quiet spot and 5 mins later it flew off as if nothing had happened.

I wondered if the dragonfly had attacked the wasp which somehow managed to crawl onto it's back but I'll never know.

Dragonflies catch and eat other flying insects on the wing. They have no sting, they grab and chew. Wasps kill and eat anything they can get.

Council pest exterminators, ~£30.

Few weeks ago we discovered a nest in the wall / roof where our garage adjoins our neighbours. As such we were getting loads of the buggers getting into the house when we opeend the windows, and also into the garage through the tiny gaps around the door.

Spoke with the neighbour, it was technically more inside his wall, so he agreed to call the council. A few days later a bloke turns up in a van, sprays some whtie powder into the nest area, and they all either die or evacuate within half a day (after going noticeably crazy in the few hours after he sprayed them).

Job jobbed.

On the same subject, if you notice a brown stain on your ceiling around this time of year make sure it’s not caused by the moisture from a wasps nest! We just had one above our bedroom ceiling, the wasp guy said if you see the stain they are about to come through. They were excavating the plaster board to make more room for the nest! That wouldn’t have been ideal if they popped through at 3am with a newborn baby in the room!

I know :-) A tiny wasp attacking a dragonfly seems unlikely especialy as it's sting was ineffictive. It's a mystery to me though.

Outside- jam jar part filled with a legal solvent, and rim smeared with jam. Waspie smell jam, flies over the neck of the jar ,gets overcome with fumes and killed by the vaporisation of the liquid. I was working in an electronics firm at time and had a young son, so this was a problem. Personally I preferred freezer spray.
