I have noticed a lot of wasps around my house recently and today I went on a
hunt! I noticed wasps going in and out of a ground floor airbrick so
presumably that's where the nest is. I was giong to ring a 'wasp trouble'
man but then thought "how will he remove it?" Assuming he will not demolish
my wall or lift my living room floor up I presume he will treat the entrance
(airbrick) with something. Before I pay said man £50(?) to do this is there
any point in me buying these foam or powder destroyers that are available.
If I can do the same as the man would but at a fraction of the cost I will.
The activity of the wasps isn't causing us any problems but I would just
like rid of the little b**gers!!
Before I pay said man £50(?) to do this is there
Yes. Nippon ant / crawling insect powder. £3 from morrisons. Sprinkle
liberally on the air brick. They will be gone in three days.
Google back for the thread in uk.d-i-y "Wasps nest under floor" on the
Or perhaps more appropriately wasp nest destroyer powder.
1. Close all windows and doors and pets/children inside (they can get
seriously hacked off, the wasps that is)
2. Late afternoon in the sun when activity is high wallop large quantity in
through and around airbrick fairly smartish - saturation bombing
3. Retire indoors and keep door shut for an hour or so.
(anti-spam is as easy as 1-2-3 - not)
I've used the nest destroyer foam before successfully, but be prepared to
repeat a number of times if the nest is big.
Also may not be advisable if there is an easier route for the wasps to
escape through gaps between floorboards or similar inside your house.
I've also heard that the ant powder works well on wasps nests!
Nope, early with the ant powder is much better. The wasps are focused on
gathering food for the nest, and a nice dose of Permethrin is what's in
Nippon ant powder (and probably the others). It will kill the nest
occupants when they bring it home and feed the others.
Yeah, but by then ye'll have to kill each one by hoping they all crawl
through the powder left out. Larger task with more wasps. By then, ye
may have to use the foam and the deadlier alternatives aimed
specifically at nests.
Carbaryl (permethrin) powder. Works outside too, when you find the
entrance. Here they make nests in the garden and in clay banks, as well
as sometimes in houses. You're lucky, your wasps are in a place you can
get at easily to do the job yourself. Late evening when they have gone
home for the night sling a tablespoonful of the powder into the entrance
so they carry it into the nest on their feet next day. They go out,
they come home, get the powder on their feet and one by one carry it
back to the nest.
And DO get rid of them. They die off in winter, sure, but not the
queens, Next season the original queen and the young ones start up new
colonies and build up to huge numbers quickly unless weather and food
supplies are in *your* favour!

I've got some here ...

Nah, it don't taste sweet.
Ah opps, should have looked at
Talcum base, Permethrin 0.5%
Think I'll live :-)
Surprisingly quick knockdown of Wasps if you can get the powder in the
We have horizontal gutter board and they find their way in to the eaves
through gaps between that and the wall boarding.
Homebase do Ant powder in 500g packs but squirting powder uphill does
not work. The D-I-Y solution has been a short length of Bundy tube
fitted to the opened out hole in the dispenser.
Why do you need to get rid?
You have stated that it isn't causing your family a problem.
If you leave them alone they will go away in autumn, and then if you block
the entrance to the air vent next spring and they will not return.
IME they don't return, even if the same access is available. Probably a
precaution against becoming predictable. Apart from a few days in late
Autumn when they have trouble finding their way home, they really aren't
A friend of mine with 2 young kids had a hornets nest above her back
door. They didn't bother anyone either.
Unless they are actually causing you or your family a problem then leave
them alone. They eat a lot of garden pests. If you really must deal with
them then the power or foam sprays work well but make sure you follow the
John, you could try RAID spray. Stand back and know where you will run
to take cover! I had one under the front bedroom floor and was mad enough
to lift the floorboards and poke at the nest. I had hornets and they went
absolutely wild. The noise was terrible and I had to put the boards down
fast! After a few hours I sprayed RAID in the nest and around the entrance.
The never returned. The nest was about 3ft long and wrapped around
heating pipes. It was amazing to see the way it was built.
You can sometimes get your local council to call as they have a service.
pay them far less than private companies.
A good coating of Nippon ant powder on the horizontal surfaces of the air
brick will do the job. £2.50 from your local £1 shop (eh???). Wait for a
cool part of the day, give the brick a good blast. Sorted.
The foams are OK, but the powder will poison the entry/exit point
effectively. I've only used the foam once, when it was impractical to use
powder (wasps entering up a verical wall), but it did the job. Expect to
pay £3.50 from your local £1 shop (eh again???).
the only advice worth having is to get in a professional, DIY attempts
to destroy wasps or nests can be hardardous and ineffective. we
covered this last year in fact-
£50 is a reasonable cost to do the job quickly and finally.
Strange how something as harmless as a wasps nest can trigger the
fear/aggression response in the male of the species. On the odd occasion
where they're a nuisance I'd pay the £50 but, otherwise, find something
else to worry about.
I learn something new every day: I always thought that bees rather than
wasps caused that problem, but a little research supports GC
That said, I'd still side with the wasps *unless* they are causing a problem
or small children or pets are likely to disturb them
