Ensign wasps are tiny parasitic wasps that feed on other insects. They’re named for the red and black stripes on their abdomen, which resemble an ensign’s uniform. Unlike other wasps, ensign wasps aren’t aggressive towards humans and won’t sting unless provoked.

Ensign wasps are beneficial because they help control populations of other insects, like caterpillars and beetle larvae. They lay their eggs inside the bodies of these insects, where their offspring will feed on the host until it dies. While this may sound gruesome, it’s an effective way to keep pest populations under control.


Ensign wasps are small - around 0.2 inches long - and have black and red coloring. They have four wings and a narrow, elongated body shape. Although they may look intimidating, they’re not dangerous to humans and won’t attack unless provoked.


While ensign wasps are generally beneficial, they can become a nuisance if they start to build nests around your home. If you notice a large number of ensign wasps in your yard, it’s possible that they’re nesting nearby.

To prevent an infestation, make sure that any cracks or openings in your home’s exterior are sealed. Ensuring that your home is free from other insects can also help prevent ensign wasps from setting up shop. If you do find an ensign wasp nest on your property, contact a pest control professional to safely remove it.


Ensign wasps are fascinating insects that play an important role in controlling pest populations. If you see these wasps in your backyard, remember that they’re not dangerous to humans and are actually beneficial. However, if you suspect an infestation, it’s important to take action to prevent them from building their nests around your home. By following these tips, you can enjoy a pest-free backyard all year round.
