Key Takeaways
Identifying blue-winged wasps is simple, with their distinct blue-black wings and yellow spots.
These wasps are beneficial for your garden as they help control pest populations and act as excellent pollinators.
Blue-winged wasps nest in soil, laying eggs on beetle grubs, with their larvae helping to reduce pest numbers, posing little risk to humans or lawns.
Identifying Blue-Winged Wasps
Identifying blue-winged wasps (Scolia dubia) or digger wasps is simple due to their distinct black head and thorax, reddish-brown abdomen with yellow spots, and striking blue-black wings.
Unlike other species like the paper wasps with slender bodies and umbrella-shaped nests or bald-faced hornets with black and white coloring, blue-winged wasps are solitary and generally non-aggressive unless threatened.
They are often seen flying low over lawns and gardens, searching for nectar or beetle grubs to feed their larvae, helping control pests like Japanese beetles and white grubs. Though intimidating, they pose little threat to humans and rarely sting unless provoked.
Blue-Winged Wasps: Nature’s Helpers
The blue-winged wasp (Scolia dubia) has a fascinating life cycle.
Emerging in early spring, these solitary wasps mate, and then the female wasp lays eggs on beetle grubs, such as the Japanese beetle and June bugs. The female digger wasp burrows into the soil to find these grubs and build nests where her larvae will feed and develop over the summer, pupating in winter.
These wasps are natural predators. They help control pest populations in your garden. Despite their striking appearance, they are generally non-aggressive and focus on finding food sources and laying eggs.
Besides controlling pests, blue-winged wasps are also fantastic pollinators. They frequently visit flowers, transferring pollen from plant to plant. Their presence can enhance the growth and beauty of your garden, making them beneficial insects despite their somewhat intimidating appearance.
Common Concerns About Blue-Winged Wasps
While blue-winged wasps are beneficial for your garden, there are a few concerns to be aware of. Here’s what you need to know:
Risk of stings. Blue-winged wasps (Scolia dubia) or digger wasps sting if they feel threatened or are mishandled, but they are generally non-aggressive. These solitary wasps are more focused on finding food and laying eggs than defending nests.
Unlike social wasps like paper wasps, they do not have a colony to protect and are less likely to sting unless provoked.
Lawn impact. Female blue-winged wasps burrow into the soil to lay their eggs on beetle grubs, such as Japanese beetles.
This activity can create small holes in your lawn, but it typically does not cause significant or visible damage. The burrowing is minimal and generally does not affect the overall health or appearance of your yard.
Should You Get Rid of Blue-Winged Wasps?
Despite their capability to sting, blue-winged wasps or digger wasps pose little risk to humans. These wasps are beneficial to have around. Because of their positive impact, getting rid of blue-winged wasps is generally not recommended.
While blue-winged wasps are helpful and usually harmless, other wasp species can be more problematic and might require professional pest control. Here are a few examples:
Paper Wasps: These wasps can be aggressive and often build nests in high-traffic areas around your home, such as eaves, doorways, and patios. Their nests can become quite large, increasing the risk of stings.
European Hornets: These wasps are larger and more aggressive than blue-winged wasps. They tend to build nests in hidden, dark areas such as hollow trees or wall voids, which can be difficult and dangerous to access.
Other Invasive Species: Some wasps, like yellow jackets, are known for their aggressive behavior and tendency to build nests in the ground or bushes, posing a higher risk of stings to people and pets.
8 Tips to Get Rid of Wasps
If you need to manage wasps in your house or yard, here are some friendly and effective tips to help you out, especially when dealing with more aggressive species like paper wasps, European hornets, and yellow jacket.
1. Regular lawn maintenance
Keep your lawn well-maintained to reduce suitable nesting sites. Mow the grass regularly and remove any debris where wasps might nest. This helps deter wasps and other insects from invading your yard.
2. Plant ground cover
Planting ground cover plants can deter wasps from nesting in your yard. These plants make it difficult for wasps to find bare soil to burrow into, reducing the likelihood of them building nests.
3. Fill in abandoned nests
Fill in any abandoned nests with soil to prevent reuse by wasps. This simple step can help reduce the chances of them returning to the same spot.
4. Encourage natural predators
Attract birds and other natural predators that feed on wasps. This can help keep the wasp population in check without using chemicals. Birds, for example, can eat wasp larvae and reduce their numbers naturally.
5. Non-toxic disruption
Use non-toxic methods, like spraying a mixture of water and dish soap on wasp nests, to disrupt their nesting activities. This can encourage them to relocate without harming them or your plants. It's an easy and eco-friendly way to deal with unwanted wasps.
6. Safe use of insecticides
If necessary, use insecticides specifically targeting problematic wasps. Be sure to follow all safety instructions and consider eco-friendly options to minimize the impact on other insects and plants. This is particularly useful for stubborn nests that don't respond to natural methods.
7. Treat nests directly
Applying insecticide directly to the nests can be effective. Be cautious and wear protective clothing to avoid stings. This method ensures you’re targeting the wasps where they live, making it more efficient.
8. Seek professional help
A persistent presence of wasps can be frustrating and challenging to manage on your own. If you have a large number of nests, it can also cause significant lawn damage and increase the risk of stings.
A professional pest control service can safely and effectively manage the situation, ensuring your yard remains a safe and enjoyable space.

Frequently Asked Questions
What attracts blue-winged wasps?
Blue-winged wasps are attracted to gardens and yards with plenty of flowers as they feed on nectar. They also seek out areas with beetle grubs, such as Japanese beetles, because their larvae eat these pests.
If you have flowering plants like the goldenrod or areas with loose soil where grubs are found, you might notice these wasps flying around.
Are blue-winged wasps aggressive?
Blue-winged wasps are generally not aggressive. They are solitary wasps focused on finding food and laying eggs on beetle grubs.
Unlike social wasps, they do not defend large nests and are unlikely to sting unless directly provoked or mishandled.
Where do blue-winged wasps nest?
Blue-winged wasps nest in the soil, where the female digs burrows to lay her eggs on beetle grubs. These nests are usually found in lawns or garden beds with loose soil. The wasp larvae eat the grubs as they develop, making the nests beneficial for controlling pest populations.
How do you encourage a wasp to leave?
To encourage a wasp to leave, use non-toxic methods like spraying a mixture of water and dish soap on the nest, which disrupts their nesting activities. You can also create a disturbance near their nest by mowing the lawn or planting ground cover to make the area less attractive for nesting.
Removing food sources like sugary drinks or ripe fruits can also help deter wasps from staying in your yard.
