Yellowjackets on Simonton Lake in Elkhart, Indiana

During the warm months around Simonton Lake, residents and visitors often notice an increase in yellowjackets buzzing around docks, patios, and outdoor gatherings. While these insects play a role in the ecosystem, they can become a nuisance—and sometimes a safety concern—when their nests are close to homes, boats, or swimming areas. Understanding yellowjackets, their behavior, and how to manage them safely can help lake residents enjoy the summer while minimizing unpleasant encounters.

What Are Yellowjackets?
Yellowjackets are a type of predatory wasp known for their bright yellow-and-black markings and aggressive behavior when defending their nests. Unlike honeybees, yellowjackets can sting multiple times and are more likely to become aggressive if they feel their colony is threatened.These insects are attracted to protein and sugary foods, which is why they are commonly seen around outdoor meals, garbage bins, and picnic areas along the lake. Their activity tends to peak in late summer and early fall wh  en colonies reach their largest size.
Why They’re Common Around the LakeLake environments like Simonton Lake provide ideal conditions for yellowjackets. The combination of shoreline vegetation, wooded areas, and abundant food sources makes it easy for colonies to thrive. Yellowjackets typically build their nests in:

• Underground burrows
• Hollow logs or tree cavities
• Gaps in docks, decks, or sheds
• Attics or wall voids in lakeside homes

Underground nests are particularly common near grassy shoreline areas. Unfortunately, these nests are sometimes discovered accidentally when someone steps too close or disturbs the entrance while mowing or walking.

Identifying a Yellowjacket Nest
One of the first signs of a nearby colony is heavy insect traffic in and out of a small hole in the ground or structure. You may see multiple yellowjackets flying in a steady pattern to the same location.  If you notice this behavior, avoid disturbing the area. Yellowjackets are extremely protective of their nests and can swarm if they perceive a threat.

Safety Tips for Lake Residents
To reduce the chances of attracting yellowjackets around your Simonton Lake property:

• Keep garbage containers sealed and located away from seating areas.
• Clean up food and drinks promptly after outdoor gatherings.
• Avoid leaving sugary beverages uncovered on docks or patios.
• Check lawn areas before mowing for signs of ground nests.
• Seal gaps in sheds, boathouses, and siding where nests might form.

When boating or relaxing near the shoreline, it’s also a good idea to keep food covered and dispose of trash quickly to avoid attracting insects.

What to Do If You Find a Nest
If you discover a yellowjacket nest on your property, the safest option is usually to leave it alone and contact a pest control professional. Attempting to remove or destroy a nest yourself can be dangerous, especially if the colony is large.  Professional pest control technicians have the equipment and protective gear needed to remove nests safely. They can also help identify potential nesting locations around your property to prevent future problems.

Ecological Role of Yellowjackets
Although they are often viewed as pests, yellowjackets do provide ecological benefits. They help control other insect populations by feeding on flies, caterpillars, and other pests. In this way, they play a role in maintaining a balanced ecosystem around lakes and wooded areas.  However, when colonies are located close to homes or recreation areas, management may be necessary to protect residents and guests.
