Ground wasps, which include yellow jackets, hornets, and cicada killers, can become problematic if their nests are located near your home or garden. These wasps tend to be territorial and aggressive when disturbed, making it essential to handle their nests with care. If you need to eliminate ground wasps safely and effectively, this guide will help you understand their behavior, identify the nests, and explore natural methods to remove them.
What Are Ground Wasps?
Ground wasps (often mistaken for bees) are a group of wasp species that tend to nest in the ground. These include yellow jackets, hornets, cicada killer wasps, and digger wasps. Ground wasps are beneficial for controlling garden pests, but their aggressive behavior can be dangerous when their nests are disturbed.
Ground Wasp Behavior
Ground wasps generally fall into two categories: social and solitary. Social wasps like yellow jackets and hornets live in colonies and are more likely to defend their nests aggressively. Solitary wasps, such as cicada killer wasps and digger wasps, prefer to live alone and typically only become aggressive when their nests are threatened. Understanding their behavior is key to safely dealing with them.
Identifying Different Types of Ground Wasps
Several species of ground wasps are commonly found in gardens and yards:
- Yellow Jackets: These wasps are easily identified by their yellow and black stripes. They are very aggressive, especially when their nests are disturbed.
- Mud Daubers: Solitary wasps that build mud nests. They are generally non-aggressive unless provoked.
- Great Golden Digger Wasps: Large, golden-colored wasps that are not aggressive unless handled.
- Cicada Killer Wasps: These large wasps are not particularly aggressive and focus on hunting cicadas for their larvae.
What Does a Ground Wasp Nest Look Like?
Ground wasp nests typically appear as small holes in the ground, with a cone-shaped pile of dirt around the entrance. The size of the hole is usually about an inch and a half in diameter, and you may find several holes grouped together. The nests are typically located in sandy or loose soil and are often found in areas near fruit trees or bushes, as wasps are attracted to sweet smells.
Natural Methods to Get Rid of Ground Wasps
Before attempting to remove a ground wasp nest, make sure it’s truly necessary. If the nest is far from your daily activities, it may be best to leave it alone. However, if removal is required, here are some natural methods to get rid of them.
Warning
Always handle ground wasps cautiously. It’s best to take action during the evening or at night when the wasps are less active. Wear protective clothing to avoid stings.
Keep Your Yard Moist
Ground wasps prefer dry soil for nesting. By keeping your yard moist, especially during the late spring and early summer, you may deter them from nesting in the first place.
Sprinkle Diatomaceous Earth Around the Nest
Diatomaceous earth is a natural insecticide that can help kill ground wasps. Sprinkle it around the nest to gradually eliminate the pests. This method is non-toxic but may take a few days to be effective.
Flood the Nest with Soap and Water
One of the easiest ways to remove a nest is by flooding it with a mixture of dish soap and water. The soap prevents the wasps from flying, and the water will drown the larvae and adult wasps trapped in the nest.
Spray the Nest with White Vinegar
Wasps dislike the smell of vinegar. Pour white vinegar into the nest at night to drive them out. This method is safe and non-toxic, but it should be done with caution to avoid irritating the wasps.
Tip
DIY wasp traps can also be effective for catching ground wasps. While they won’t eliminate a nest, they can help reduce the wasp population around your yard.
Seal the Nest
If you can see the nest entrance, sealing it with dirt or plastic can suffocate the wasps inside. This method may not work for larger nests, but it can help reduce activity in smaller nests.
When to Call a Professional
While DIY methods can be effective for smaller nests, it’s important to call a professional exterminator if the nest is large or if you are allergic to wasp stings. A professional will have the proper equipment and expertise to safely handle large infestations.
