Minnesota sees surge in yellowjacket stings due to warm fall extending their activity and colony growth.

Minnesota is seeing a sharp rise in yellowjacket activity this fall, driven by late-season warmth that extended their breeding and foraging periods. Colonies have grown larger, with some reaching up to 5,000 wasps, increasing encounters at outdoor gatherings and homes. Experts advise reducing attractants by securing trash, avoiding open food, and using soapy water for individual wasps, as no effective repellent pesticides exist. The surge has led to more stings and disruptions, prompting residents to take preventive measures.
