Weather takes toll on Wis. wasp population

Posted:

MADISON, Wis. (AP) -- The state's wasp population seems to be down this year, possibly because of the wetter spring and cooler summer.

Phil Pellitteri is a bug expert at the University of Wisconsin-Madison. He says every summer he gets calls about wasp problems from farmer's markets or outdoor restaurants. He says this year he hasn't gotten any complaints.

The wasps in question are German yellow jackets. They're yellow and black and generally have nasty tempers.

They thrive in hot weather, which Wisconsin has had little of this summer. They also nest on the ground, making them especially vulnerable to rainy springs.

German yellow jackets generally start getting more aggressive between August and October. Pellitteri says this year wasps might not appear until mid-September.
