OSU entomologist Gail Langellotto warns against going after yellow jackets, especially with pressurized chemical pesticides. Bees could be affected, or people can blast themselves, accidentally. It’s just better to wait.
“Yellow jackets do not reuse the same nesting site from year to year. They eventually take off in the fall-winter time period. They will get rid of themselves, if you can wait it out,” Langellotto said.
Langellotto recommends wasp traps, available at gardening or hardware stores. However people approach these insects, she recommends caution. Unlike bees, yellow jackets can sting repeatedly.
