Should I try to kill or trap yellowjacket queens in the spring?

No. In terms of the number of wasps that will be around in late summer, when it really matters, eliminating queens in the spring has no real effect. Studies have shown that eliminating even 95% of the queens in an area does not reduce the number of foraging wasps later in the summer and the reason is pretty simple.

The few queens that survive build larger nests because their competitors have been eliminated. So, don't waste time trying to trap or kill queens in the spring. Instead, use our management suggestions (see Treating Yellowjacket Nests).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
