Wasp Grubs

I have found a couple of wasp nests that are easy to get to, can anyone recomend a spray insecticide or similar which I could use to kill the wasps.
I would obviously only use something whose residue will not harm fish, or taint the grubs with its smell.

It's hard to say now that so many of the chemicals are no longer available (CYMAG and anaesthetic solvents). Personaly I have used petrol to good effect but it has to be in a place where there is no fire risk.
Here's my method. But I am sure many others have their own. Quietly approach the nest and throw half a jam jar of petrol onto the entrance and retreat. Wait several minutes and throw a lighted match in. There will be a loud wosh as the vapours ignite killing any wasps in the air and most of them in the nest. Give it a few hours and if all calm open up the earth around the nest with a spade - one quick stab and a wiggle generally does it. Then repeat the petrol routine. If there is still signs of life after another few hours repeat again. Dig out the next day if all quiet.
Good luck.

theres two ways i've used in the past one
requires a c02 fire extinghisher the other
a bucket of water

c02 method:wait till dusk (the wasps like a
early night)the wasps will be tired and ready for bed ,spray the jet of c02 into the entrance to the nest for at least a minute the c02 will chill them and make them dorment split the nest find the queen and kill it (if around residential area)and
shake out all the wasps squirt with c02 if
need bee to further subdue the wasps,put the nest in a sealable bag or bucket.

Bucket method:get yourself a sturdy bucket
with a sealable lid and a sponge ,glue the
sponge to the lid of the bucket(underside)
then fill it with water to about 1in from
the rim,depending on where the nest is ,if
its in the ground then you'll have to cut around the nest with a spade first to make
it easier to scoop up,right the idea is to
drop the whole nest into the water and then
quickly seal with the lid,the sponge will
ensure the nest dos'nt float and all the wasps will drown.best done after dusk when
they return to the nest for the night

there is still a risk of being stung with
both methods and if you miss the bucket or
the c02 fails to subdue the wasps then you
have to run,run for your life as you have
just made them wasps very angry and you are
not going like them when they're angry !!!
i've never done it with out getting STUNG !

i don't like to use chemicals if i can help
it so as to avoid tainting the nests,i make
the nest into paste by grinding up and then
adding fresh ground breadcrums and water, &
after removing the grubs i store them in a
tub in a cool fridge till needed.

i hope this helps

Let someone else do it!!!

this probably sounds stupid but what do you use wasp grubs for and what are they?

Wasp grub are/is the absolute 'dogs' for chub fishing. In fact it was so good that some match men specialised in using it and won a lot of money but as with most things it got banned.

Usually it is fished in conjunction with the balsa float and people like Dave Thomas and others cleaned up on the Trent and the Yorkshire rivers in the 1970's.

Mash the nest up too with some brown crumb. Best groundbait of all.

thanks fishing gimp!

Try smoking them out.
Or better still ask a beekeeper or a bee rustler they have been in the news in Cheshire recently on tv.
Visit a library the may bee some books in there.

I've got a massive wasp nest in my flat roof at present,unfortunately the gap in is only 4" .but i can hear them a full 6feet in ,above my head in the kitchen.Hope the ceiling doesn't decide to give way!!!

I,ve got it with no bites, gave B & Q wasp nest killer a try, it advised an eight second spray, I gave it 2 seconds. Been back tonight and collected it, all the mature wasps were dead, all the grubs and a few of todays newly hatched wasps are fully alive.
Its now in the freezer to kill off the wasps altogether and to preserve them until this weekend.

we had an underground wasp nest in our back garden a couple of summers ago....cost us ?30 for a lady from the council to come around give 2 squirts of some white powder into the nest.
it took her longer to put on her protective clothing than it did for the actual job in hand!!!

I just spoke to FJT about how to get your wasp grubs. When he was a young guy, they used to locate the wasps nest and then, after dark, light a fire on top of it. Not only did that kill the wasps but it roasted the grubs in the nest too. For obvious reasons, it is best to ensure that the grubs are dead because if you leave them in a bait box for a couple of weeks you might just have a problem when you open it again.

Just a thought since I originally posted this. Like many other people these days, I have a vacuum sealing unit in the kitchen and I would think that if you put a wasp's nest in a bag, (you might need to make one up from a roll of the material) and then evacuated it it is unlikely that neither wasps or their grubs would be able to do anything after a couple of days.

Don?t know if this is true or not, but a bloke here at work reckons the way to find a wasps nest is to watch how they are flying and look out for ones going in a straight line.


Apparently they always fly in a straight line back to the nest ?

i think i'll be sticking to the meat and slugs thanx

the mother in law chews wasps

Flying straight back to the nest. That is quite true Beecy. Old Webby once told me that.
