Beautiful summer day with the house hives in the background. Bees love poppies.
Wasp biology being what it is.. I fear that summer of 2019 will be worse than 2018. Wasps produce lots of queens at the end of summer, who then mate, find somewhere to tuck in for the winter at first frost and then become dormant till spring – then they start the process with a new nest site. The milder and longer the autumn, the more queens that are produced and the longer the parent nest can keep on going with brood production. Brood production requires food procurement -especially protein (hence your picnic is ruined) and honey bee colonies can be stripped clean of EVERYTHING, your entire apiary can be wiped out before you know it. And it is not a gentle event.
