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
