As I understand it; ....gave up writing on this, copy pasted from google.....
"The lifecycle of a wasp colony is closely tied to the seasons. After hibernating through the winter, queen wasps emerge in spring to build new nests and lay the first batch of eggs. By early summer, the colony starts to grow rapidly, with hundreds — sometimes thousands — of worker wasps helping to feed the young and expand the nest.
By late summer, however, the dynamic shifts. The queen stops laying eggs, and the workers have fewer tasks to occupy them. With their natural food source drying up, they begin foraging more aggressively for sweet, sugary substances — which is why they’re suddenly everywhere: around your drinks, your bins, your barbecues, and even indoors.
This is also when wasps are most likely to sting. Without their usual role in the colony, they become irritable and territorial. A sudden movement or accidental swat can quickly provoke an attack."
That last phrase is very much our experience here.
