What It Is

The European hornet (Vespa crabro) is the only true hornet (genus Vespa) established in North America, introduced from Europe. It is primarily a species of the eastern and southeastern United States. In the Los Angeles and Orange County area, European hornets are uncommon to rare. Size: 1 to 1.4 inches, the largest stinging insect most North American homeowners encounter.

How to Identify

Color: brown with yellow banding and some reddish-orange coloration, especially on the head and thorax. Distinctly larger than yellowjackets. Smooth wasp body. Nocturnal activity is a behavioral identifier: European hornets fly at night and are attracted to outdoor lights. If you see large wasp-like insects at your porch light after dark, European hornet is a possible candidate. Nest: enclosed paper nests in hollow trees, wall voids, attics, or other cavities.

Behavior and Risk

European hornets defend their nests. They can sting multiple times. Venom causes pain and swelling. Allergic reactions possible. Nocturnal foraging is typically low risk; workers hunt moths and other insects near lights and are not targeting people.

How to Handle

If you discover a nest in a wall void, attic, or tree cavity, do not disturb it. Contact a pest control company. Reducing outdoor lighting during warm months may reduce nighttime forager activity near the home.

Quick comparison

European hornets are much larger than yellowjackets and have brown/yellow coloring rather than the stark yellow-black of a yellowjacket. They are also active at night, which yellowjackets are not.

What our customers say

★★★★★
We live in an apartment complex where beecasso was kindly called to be of service by our apartment management team, to address a cluster of bees that were trying to make their home on our patio. Not only did Beecasso team member, Caleb, come out next day, he was incredibly professional, thorough, and kind during his service. Jerry, another Beecasso team member, also came out the following day and followed the same professional, empathetic, and efficient service that we received the day prior. After the treatment, we had a question about the lingering bees and called the service line that was provided to us on a handout given by Caleb on the first day, explaining more about the process. Steve, the manager / owner, answered and was incredibly knowledgeable, reassuring, and committed to helping the issue resolve. All I can say is that with every interaction, Beecasso was exactly the type of service team that I would hope to address our concerns. They were also extremely sensitive to the alarm presented since we have a bee allergy in our home, and also a tenant next door also has a bee allergy as well and we just wanted the bees gone. So, it was really important to us that no straggler bees entered our house as each service person came and went through our home to the patio. Each member of the team were so cautious and attuned to help keep the inside “bee-free.” Although this is not our property, we are beyond thankful that our management found / contracted this business because they truly were everything we could have hoped during this unsettling process.

We had such a great experience with Beecasso recently. Two technicians came out and they were incredibly professional and kind. They were wonderful with my kids and made sure we felt comfortable throughout the process. They efficiently removed a super large beehive from our garage and did beautiful repair work afterward. The bees were gone quickly, and you'd never know there had been a problem. I highly recommend this company for their expertise and genuine care for their customers!

They came within a day of my calling to relocate my bees. The owner on the phone conveys genuine concern for the plight of bees and doing the best that he can for them. The gentleman who came were friendly and professional.
