The hut has a very large wasp's nest in it again this year, as it has
had for the past few years. Other than setting fire to the hut, what
would work to deter them from making a new nest next year please?

Find out where they're coming in and put a fine mesh screen over the
hole, or block it completely with e.g. foam filler, this winter. But I
guess you've already tried that, as it's a pretty obvious thing to do!
The textbooks will tell you that every nest is started from scratch by
a new queen after she's emerged from winter hibernation, and that old
nests are just empty shells with no live or active wasps in them. But
if you've been getting nests in the same place for several years in
succession, something must be attracting them to the site. Do you
clear out the old nest every year before the following Spring? It may
have a residual smell that attracts a young queen looking for a nest
site in Spring. Painting the hut with smelly creosote, Jeys Fluid or
diesel may repel them, but will probably repel you as well!
"Wasps do not generally return to the same place year after year,
however some roofs are favoured for their position and habitat."
I have had for a couple of years wasps trying to build a nest in my
shed, I catch them early and use a fly spray, then run like hell. I do
this a couple of times when there are few wasps around and it just kills
them off and stops the nest building.
I think you need to catch them at the beginning of the season before the
colony builds up as they are agressive little s....!
Prolly takes them a while to get aggressive. Other day I was emptying
the grass box off the lawnmower in a new spot only to see, towards the
end of the cut, a number of wasps obviously stacked by ATC as I'd
covered the entrance with grass cuttings.
I have killed off a mature nest by using that foam spray stuff from a
distance of 10 feet or so, seemed quite safe.

Aye, getting at 'em at the ping pong ball stage is the easiest. Also
note the hibernation bit, the queens may well be hibernating in the
shed/hut/WHY, a good dose of wasp 'n fly killer a couple of times in
the winter will put paid to them.

If the wasp can get in so can the fly killer. It's pretty toxic

I have a fair bit of moss on the roof, and in April, the tiny yellow
flowers attract the wasps. They then make their way into the loft. To
deter them, each spring I used to install three or four Vapona devices
in the loft (which would also do for any woodworm in the fly phase of
their lives). Several month later, I would replace them. I now have to
simulate them by spraying fly/wasp killer onto an opened-up newspaper,
and then re-folding the newspaper.
Unfortunately, fly/wasp killer doesn't seem to deter those pesky
The diesel will certainly make setting fire to the hut easier, but may
take a bit of explaining to the insurance company. I'm sad to say that
both Jeys Fluid and Creosote would both probably attract me, does anyone
else like the smell of these?
If you remember take a look at the beginning of next year and try to
spot a new nest in the making. We regularly had them in the stable at
home and the first time I'd notice them they were only the size of a
ping-pong ball and easily destroyed, preferable with the queen at home.
Any product with pyrethrin in it does a good job and is harmless to
My wife has great faith in the imitation wasps nest hung under our
eaves. I think the theory is that the new Queen sees this humungous
established nest and decides to try elsewhere.
It didn't work very well this year:-(
They need a source of softened wood to chew up for the nest. Perhaps
your hut has reached the appropriate stage of decomposition:-)
I find Nippon nest destroyer effective if the nest is in sight. I also
try to kill the young Queens when they feed on the Cotoneaster blossom
just outside my office window.
With the funny spring this year, there were lots of alternative food
sources so we had several nests.
3 find that once the wasp nest is established the best thing is to go
out after dark and spray with one of the wasp killer products. Has
worked a number of times for me with not ill effects, except on the wasps!
There are several YouTube videos about the Waspinator.
I note that it seems to be something like 'sage green' in colour. I have
a garden seat painted sage green, and on a sunny day, it gets covered in
loads of small flies. I presume that there's something about that colour
that attracts them (possibly their eyes are particularly sensitive to
it?). As others (and the videos) have said, the wasps are probably
fooled into thinking that there are others already in possession of the
territory, so they look elsewhere to build their nest.
I've had successive wasps's nests in my shed and in my roof
space for years now and have never been troubled by them.
If there are babies or young children around who might
be at risk then obviously things would be different.
But I find their nest building activity a source of
inspiration myself, same as the did the Chinese with
the invention of paper, supposedly.
