Boric acid OK, but DE or silica gel? These work from outside interfering
with the cuticle wax layer (some claim they'd block spiracles, but
that's guesswork and not yet proven). I do not know any mention that
they'd have any potential as stomach poisons.

A mixture of vinegar (a lot) and strawberry jam (some) once attracted
some 600 wasps per day (for almost three weeks) into a funnel trap I had
put up on my balcony ... a drop or two of detergent helped them drown.
OK, that's not the bait idea you're pursuing - but that, after all, may
not exactly be what you want anyway: Where's the benefit to bait
countless wasps without knowing where their nest(s) are?
You might be killing off dozens of nests all over the place without
seeing one wasp less where they disturb you. OTOH, when you can access
the nest you can save yourself the baiting troubles and go about the job
the easy way.
There's only one purpose baits could serve when dealing with wasps, and
that's attracting them away from areas (like placing a "ring" of baits
around a food premises in order to have wasps visit your traps rather
than the inside).

Regarding European Wasps, you mentioned the following *might* work as
possible posion baits -
"Boric acid OK, but DE or silica gel"
Can you please elaborate on this? I could not fully understand what
you were saying. I am well aware of how to build a European Wasp
"Trap", but not sure about how to bait them.

Not Uli, but Boric acid is a stomach toxin and is an ingredient of
many ant/roach baits, so theoretically it may work with the wasp bait if
they do eat it. Where as DE and silica gel are desiccants, they
basically cut into the waxy outer layer of an insect as they crawl
through it and they "dehydrate", they are not taken internally. I threw
out silica gel may work for more than once while attending seminars a
speaker has mentioned using silica gel in a bait matrix with success,
though the mixtures seem to be the opposite of what boric acid is.. very
little with BA heavier mixture of silica gel and I am not sure if the
thought is to kill them internally or if because an insect is digging
into the bait it will be scratching it's outer surface. Though my
personal opinion is, for wasps what you are trying to accomplish may not
work.

I read your message above. Thankyou.
Boric Acid may possibly work against European Wasps......in theory.
Perhaps.
Having said that, there are a few points I would like to mention:
We have a commercially available product where I live called ANT-RID
liquid (with Boric Acid derivative), or ANT-RID baits (with
Firpronil). The Anti-Rid BAITS are in a cartridge type set-up, similar
to cockroach baits.
http://www.antrid.com.au/
If you were going to use one / both of these products, any advice at
all?
Would you mix them with meat, as European Wasps are strongly attracted
to meat?
What would happen if you mixed household Borax powder with honey and /
or meat?
Any general suggestions?

Sorry I really don't have an opinion on if you would be able to create a
wasp bait by using the ant baits. The manufacturer has their recipe
pretty fined tuned towards the target pest (ants) and changing it up
just a bit may make them less desirable to the target pest, much less
any other insect. Wasps in general will be attracted to liquid sweets in
the Spring and Fall. In the Summer months (I forget how it works down
there, is your Summer months Dec , Jan, Feb, or do yall just consider
your Winter hot and Summers cold)..any who, in the hot months they chew
on meat which in turn they feed to their larvae that turns the meat into
a sweet liquid and they now feed the adults. So the time of year when
the nest is not producing larvae they will be feeding on nectar...soda
water..beer etc. This is the best times to try to reduce the numbers
with a trap though I have heard of people using tuna fish in the traps
during the hot months and still catch wasps.

Borax would do - its easy to get, quantities of about 1 to 2% are used
in ant rid. Ants and bees are descended from wasps so the same kind
of chemical will kill them. Tartar emetic is used too, but is harder
to get - try a homiopathic chemist. Lead acetate may do the job too,
but could leave toxic remainders in the environment.
I would not expect that silica gel would be harmful to eat.
