Seen more yellow jackets this year? You’re not alone


PORTLAND, Ore. (KOIN) — It’s not unusual to see yellow jackets in yards and gardens this time of year, according to Gail Langellotto, an entomologist at Oregon State University. 

“But what I think is unusual this year is that they’re much more numerous,” Langellotto said. 

“We’re seeing many more of them this particular year.”

Langellotto said the cause for the influx of wasps and yellow jackets might have been a drier spring combined with a recent drought in the area. 

“It really is just so dry in the surrounding landscape right now that the yellow jackets are coming to peoples’s yards and gardens because they’re able to find the resources they need that they’re not able to find elsewhere,” Langellotto said. 

Those wasps will be more common in yards that have fruit trees — the yellow jackets are sugar hungry, Langellotto said — and those that have other insects in them which the wasps can prey on.
