Researchers at Oregon State’s Department of Horticulture say this year is very similar to last year. They’ve taken quite a few calls this month for bald faced hornets in the Corvallis area.
“The yellow jacket activity appears to be way higher than in the past. I had three phone calls on Friday, and I feel that likely a year ago I would have felt three phone calls in a week was about normal,” said Jeremy Brown, Bye Bye Pest Control exterminator.
Yellow jackets do serve a purpose, eating pests that can damage plants. But, they can also be aggressive.
Wasps and yellow jackets die during the winter, except for the queen.
