They've been terrible around here. Trying to eat outside is impossible. I've seen them attacking honey bees too.

Same here. They took over the bird watering station. There must be a big nest or two around.

I bought a yellow jacket trap for the first time; it works pretty well, but they keep on coming.
Is it because the trap attracts them? Just wondering if it's a vicious cycle.
