Hornets are a social species of wasp. Not known for pollinating, they are still beneficial in a natural environment. They hunt other insects to feed their young. Later in the season, they scavenge for sugary foods such as overripe and rotting fruit.

Why Get Rid of Hornets?

Around humans, hornets become pests. They damage homes, possessions, gardens, and people. They do not make for good neighbors.


Hornets are aggressive when they feel threatened. They are also protective of food (including yours, when outdoors, that they have targeted as their own) and their nest.

A hornet sting is powerful and painful. It injects a pheromone to alert others nearby to attack as well. A nest can contain 700 or more individuals each capable of stinging and biting multiple times.

Another chemical in the hornet’s sting signals your body to feel intensified pain. A single sting produces pain and swelling that can persist for several days. Seek medical attention in case of an allergic reaction. Stings become dangerous to humans at around ten stings per pound whether allergic or not.

Hives or Nests

Hornets - European Giant Hornet Nest - Croach Bee Control and RemovalThe queen hornet builds a nest in a high, dark place.

In urban areas, hornet workers collect garbage and other non-natural nest materials. They will scrape wood from the sides of homes, fences, and obtain other fibrous materials to do the job.

In nature, hornets gather wood from trees and other plant material to build their nests.

Hornet Identification

The Baldfaced Hornet is black and white and commonly considered a hornet species, but is actually a Yellowjacket.

The European Hornet, also known as the Giant Hornet, is the only true hornet variety in North America. It is not black and white; instead, it is similar in appearance to yellow jackets.

Pest Control - Bees of Seattle - Croach - Kirkland, WA - European HornetEuropean hornets have two sets of wings, the front larger than the back. Unlike wasps, these wings are orange-brown. They are often folded back along the body when at rest.

Hornets have wider heads than other wasps, and the head is red-orange and brown in coloration. The rest of the body is yellow and brown. They have the same thin waists of wasps, but shorter, with rounded abdomens.

They are much larger than a standard wasp, sometimes reaching more than two inches. Hornets are also the only wasp that flies at night.

Their nests are usually unassuming and challenging to see. They may be found high in trees, as an opening underground covered by leaves, inside attics, or hanging from eaves. They grow larger through the season, reaching the size of a basketball. A hornet nest looks like a paper mache teardrop with a single hole at the bottom.

Life Cycle

Bee Control - Croach - Kirkland, WA - Hornet nest with eggsThe hornet queen starts by building a small nest and lays eggs. Once the workers hatch, they enter a larval stage for about eight days.

The queen or other workers feed them. Then they seal their cell, which looks like a honeycomb, and spend two weeks as a pupa.

The fully developed hornet worker emerges and begins its job of building the hive and feeding the young.

Near fall, the queen lays future female queens and fertile males. After emerging from the nest, these hornets mate with those from other hives. The new queens find a place to hibernate through winter. All others die off.

In spring, the new hornet queens emerge and start the process over.

Nest Removal and Control

Hornets prefer to build hidden, aerial nests in vegetation. Therefore, we suggest keeping trees and landscape bushes well-trimmed, thinned, and open. Ongoing treatment prevents their return. Your Croach® technician can advise you on others exclusion steps that make your home less appealing to hornets.
