Perhaps the wasps are forming bigger colonies to form a stronger defense and/or offense against the opposing killer wasps invading the area. It might
be that plenty of food is also available or such a large colony wouldn't be able to exist without a big enough food supply in the area. That would
be sort of like you don't have big cities unless you can bring in food from other areas. If you couldn't bring in enough food, you would just end
up with small cities.
I prefer exterminating all wasps and dangerous insects around my house. One wasp caused me all kinds of trouble when all I was doing was cutting my
grass. I'm allergic so it's a war to me now if they invade my territory.
