Wasp Identification

What are wasps?

Wasps are a common type of stinging insect found in the Roseville and the greater Sacramento area. These insects have stingers on the end of their abdomens they use to paralyze their prey and defend themselves. A wasp's exact appearance depends on the species, though most wasps have a few similarities: they have a pinched waist, two pairs of wings, six long, skinny legs that dangle down when in flight, and their bodies are usually hairless.

Many species of wasps are predators that help control nuisance insects by feeding on them. They are also responsible for some pollination. When living outside, away from people and our homes, wasps are a valuable part of the ecosystem. The most common wasps in our area include paper wasps, mud daubers, and yellow jackets.

Are wasps dangerous?

Wasps can be very dangerous to people. Most wasps have smooth stingers and can sting their victims many times, injecting more venom with each sting. In addition to their painful stings, those sensitive to their venom experience allergic reactions or anaphylaxis. However, stinging insects are rarely a problem for people unless:

• Wasps have established a nest in, on, or near your home or outbuilding.
• You come too close to a stinging insect nest.
• You provoke them, whether attempting to remove a nest on your own or simply mowing your lawn.
