There are several species of yellowjackets. These flying insects typically have a yellow and black head/face and a patterned abdomen.
Yellowjackets are social insects that live in nests or colonies with up to 4,000 workers. They are most active in the late summer and early autumn when a colony is at its peak. Yellowjackets feed on sweets and proteins, and therefore commonly invade outdoor events.
Yellowjacket stings pose significant health threats to humans, as they are territorial and will sting if threatened. They are known to sting repeatedly and can cause allergic reactions. Yellowjackets and other stinging insects send over 500,000 people to the emergency room each year.
Yellowjackets can be found anywhere humans are found. They build paper carton nests out of chewed up cellulose, which are usually found in the ground or in cavernous areas such as eaves and attics.
Call a pest professional if you suspect yellowjacket activity on the property. Because of their tendency to sting when threatened, yellowjacket control requires specialized equipment and safety precautions. Homeowners should remove garbage frequently, keep trash cans covered, and ensure all doors and windows have screens that are in good condition. People should also avoid wearing sweet-smelling perfumes asnd the scent attracts yellowjackets.
Yellow jackets are omnivores that feed on proteins like insects, meat, and fish, as well as sugary foods like nectar, fruit, and sweet drinks. This is why they’re often unwelcome guests at outdoor cookouts and picnics.
Yellow jackets are most active in late summer and early fall, when their colonies are at peak size, and workers forage aggressively for food. They tend to be most active during warm, sunny days and will retreat when temperatures drop.
To help repel yellow jackets, keep food and sweet drinks covered outdoors and secure garbage cans with tight-fitting lids, as yellow jackets are strongly attracted to food waste and sugary substances. Avoid bright colors and seal any cracks or gaps around your property that could serve as nesting sites.
