Joe asked about wasps:
> Any other ideas ?
You need to be careful about the type of trap that you use; it is crucial
that no wasps escape because they will simply recruit their friends to come
to the party!
Jam jar traps may catch large numbers of wasps but, if you watch, many do
actually escape. I had the same thing with wine bottle traps - they soon
filled, but I seemed to have more and more wasps arriving every day.
I have known beekeepers add a poison to wasp bait, but I am not sure that it
does much good; it would have to be at the right strength not to kill the
wasp before it returned to the nest and even then might not do any good (or
harm depending whose side you are on!). Wasps do not feed their larvae with
sweet material (the larvae are carnivores), and do not share food with each
other a far as I am aware, so you might still only poison the adult wasps
that take your bait. There would be a much greater danger to bees if they
were attracted to the bait, as they would feed larvae and share the poisoned
food.
