Wasps are evil, pointless, horrible, agressive, miserable, stinking things so the more traps the better..........
They've got a liking for my bald patch
Well sorry I have to disagree with you there, Yes they are an issue to our bees, I found this thread whilst looking for traps as I now have an issue big time with them coming into house;
HOWEVER they eat afids and grubs and I have even seen them tackle cattapilars that my chickens wont touch.
EVERYTHING in nature is there for a reason. yes they smart when they sting, but have you ever looked at a wasp nest in detail? WOW they are stunning pieces of engineering I couldnt build a house let alone a sculpture like their each year!
Wasps bother me and my apples more than my bees.
