I live in the Leektown area, and for the past two years have seen a scarcity of paper wasps (polistes). We see a few queens in the spring and then no more. I have three open eaved sheds, and porches, that have to be scoured for nest removal (usually two or three per shed), but the past two years, no nests. The same is true for flowers here, lot's of solitary wasps and bumble bees visiting, but no wasps..any one else noticing this? Or have any idea as to why they have disappeared?
