Stinging insects like wasps, yellowjackets and hornets are more active and aggressive in early fall, a New Mexico State University entomologist said. Until then, he advised being aware of and cautious around the stinging insects. Common sense is the best method of dealing with these insects, Cain said.
Most wasps are actually beneficial insects, and capture many pest insects to feed their young.
If nests are not in high-traffic areas where they are likely to be disturbed or stumbled upon, simply avoid the areas. Loud noises, including those made by power tools, can upset the insects. Be sure not to bump into nests, because the insects may become agitated. Multiple stings are not unusual. If the wasps are aggressive and removal is necessary, it may be a good idea to get assistance from a pest control company or beekeeper.
