For non aggressive wasps I've had great luck spraying the nests with this Spectracide wasp remover in the evening. For more aggressive wasps I also use this rediculous looking upper torso Beekeeping suit. It seems silly, but trust me, it's amazing.

Why Understanding Wasps is Important

While wasps can be intimidating, they play an important role in our ecosystem. They help control other insect populations, pollinate plants, and provide food for other animals. However, some species can also pose a threat to humans if they feel threatened or if their nest is disturbed. Understanding wasps and their behavior can help you avoid getting stung and coexist with them peacefully.

Common Types of Wasps in Oakland

There are several types of wasps that are commonly found in Oakland, including:

Paper Wasps

Paper wasps are a common sight in many California backyards. They have long, slender bodies and are usually brown or orange in color. Paper wasps build nests made of paper-like material, often under eaves or in trees. While they can sting if provoked, paper wasps are generally non-aggressive and will only sting if they feel threatened.

Yellow Jackets

Yellow jackets are another common type of wasp in California. They are usually black with bright yellow markings and are known for their aggressive behavior. Yellow jackets build nests in the ground or in structures such as walls or attics. They can be very territorial and will sting multiple times if they feel threatened.


Hornets are a type of wasp that are larger than paper wasps or yellow jackets. They are usually black with white or yellow markings and build large, aerial nests. While hornets can be aggressive if their nest is disturbed, they usually don’t sting unless provoked.

Identifying Wasps

Identifying wasps can be tricky, but there are a few key characteristics to look for. Wasps have long, slender bodies with a narrow waist and two pairs of wings. They also have chewing mouthparts and can be identified by their distinctive coloring and markings. If you’re not sure what type of wasp you’re looking at, it’s best to keep your distance and avoid disturbing it.

Dealing with Wasp Nests

If you discover a wasp nest on your property, it’s important to proceed with caution. Disturbing a wasp nest can be dangerous and may result in multiple stings. If you need to remove a wasp nest, it’s best to call in a professional pest control company. They have the tools and experience needed to safely remove the nest without putting anyone at risk.


Now that you know more about the different types of wasps you might encounter in Oakland, California, you can approach them with confidence. Remember to always observe wasps from a safe distance and avoid disturbing their nests. With a little understanding and respect, you can coexist peacefully with these important members of our ecosystem.
