Yellow Jackets

What do yellow jackets look like?

Yellow jackets are small, aggressive wasps that are easy to identify due to their distinct appearance. Yellow jackets are about ½ inch to ¾ inch long and have black and yellow striped bodies. Some species may have a slightly orange to reddish hue mixed with black. These stinging insects have narrow waists that separate their thorax from their abdomen. Their bodies are smooth, not fuzzy. They have transparent wings and long, segmented antennae. Female yellow jackets have a smooth, retractable stinger they can use multiple times, unlike bees that sting only once. 

Are yellow jackets a type of wasp?

Yes, yellow jackets are a type of wasp and belong to the Vespidae family, which includes several wasp species. They are known for their aggressive behavior, especially when defending their nests, and their social structure, which consists of a queen, workers, and males. Yellow jackets share many traits with other wasps, including their slim waists, smooth bodies, and retractable stingers, which allow them to sting multiple times without dying. Unlike solitary wasps, yellow jackets are social and work together in colonies to build nests and gather food. They feed on nectar, sugary substances, and protein-rich foods like insects, making them both predators and scavengers. 

While all yellow jackets are wasps, not all are yellow jackets; other types, such as paper wasps and hornets, differ in size, appearance, and behavior. You can easily recognize yellow jackets by their black and yellow markings and ability to nest above and below ground.

What do yellow jackets eat?

These insects live on a varied diet of sweets and meats. In nature, they get sweets from nectar and honeydew and protein from insects and bugs. In and around residential properties, they feed on food in open trash receptacles and dumpsters and food and drink remnants left in outdoor living spaces.

Are yellow jackets dangerous?

Yellow jackets are dangerous, particularly due to their aggressive behavior, tendency to attack in large numbers, and painful stings. Their stings can cause pain, swelling, and redness at the site. They may lead to more severe allergic reactions in some individuals, such as difficulty breathing, swelling beyond the sting site, or anaphylaxis, which requires immediate medical attention. 

Can yellow jackets damage my property?

Yellow jackets can damage your property, particularly when building their nests. These wasps often construct nests in hidden or hard-to-reach areas, leading to cosmetic and even structural issues. 

Sometimes, yellow jackets may chew through materials like wood or plaster to create access points for their colony. Ground-nesting yellow jackets can also disturb landscaping, damaging lawns, gardens, or flower beds by creating underground nests. 

Where do yellow jackets build nests?

Ground-dwelling yellow jackets prefer to build their nests in rodent burrows, tree cavities, and the root systems of trees. They use available ground cavities and tunnels and make them larger. If they find loose soil, they may excavate a hole from scratch.

When yellow jackets explore a home's exterior, they may enter through small gaps and create nests in wall or ceiling voids. They also get into attics and build nests inside stored items.

How can I tell if I have yellow jackets around my home?

Detecting yellow jackets around your home involves observing their behavior, appearance, and nesting habits. Yellow jackets are typically active during the warmer months and are easily identified by their black-and-yellow striped bodies and rapid, buzzing flight patterns. You might notice them hovering near food sources such as trash cans, outdoor eating areas, or flowering plants as they forage for sugary substances and protein-rich foods.

Another clear sign of yellow jackets is the presence of their nests in the areas noted above. Ground nests may appear as small holes with frequent wasp activity, while aerial nests resemble paper-like structures attached to a surface. You might also hear a faint buzz if a nest is hidden within walls or other enclosed spaces.

If you frequently see these wasps flying near your home or spot a nest, it indicates yellow jacket activity. 

Are yellow jackets attracted to outdoor gatherings?

Yes. Yellow jackets love to show up uninvited to outdoor gatherings:

• They are attracted to sugary drinks, including soda cans.
• They are drawn to protein, including hamburgers, hotdogs, and meat.
• They are attracted to the scent of decay and will get into trash receptacles for a meal.
• They eat insects, such as flies and ants, which are also attracted to outdoor gatherings.
