How to get rid of European hornets
Vespa crabro
Need a look-alike split? Use European hornet vs yellowjacket, then follow the control sequence on this page.
European hornets (Vespa crabro) nest in hollow trees, barns, and wall voids. They are larger and browner than yellowjackets and may fly at lights after dark. A void nest is a professional job. They are not the Asian giant hornet. Photograph for ID, keep people away, and repair the cavity in winter.
European hornets are true Vespa — larger and browner than yellowjackets — nesting in cavities and sometimes flying at night lights. They are not the Asian giant hornet. Control of a void nest is professional. Change bedroom lighting and screens if they batter a window. Established in the eastern US for generations; do not import internet panic.
How to identify European hornet
- Large brown-and-yellow vespid.
- Cavity nests, not small open eave umbrellas.
- Can fly after dark at lights.
Signs of an infestation
- Large wasps at night lights.
- Traffic into a barn soffit or hollow tree.
Biology and why they show up
Social cavity nesters. Predators of other insects.
Health and property risk
Stings and void nests. Misidentification as “murder hornet” causes harmlessly wrong treatments.
Proven control sequence
Work in this order. Skipping inspection or exclusion is why most “treatments” bounce back in a week.
- Get an ID. Photo to extension. Vespa mandarinia is a different insect.
- Cavity nests: hire help. Same caution as yellowjacket walls.
- Reduce night lighting at bedrooms. Screens; warmer-spectrum bulbs sometimes help.
Matching tools for these steps can be bought on Amazon. Buy the field kit.
Tools around European hornets
Often in a void or outbuilding. Identify first — this is not a yellowjacket picnic trap job.

Labeled product
Wasp and hornet foam spray
A labeled jet for a small, visible eave nest at dusk — not a broom, not a daylight attack, not a wall void. If you are allergic, this is a 911 plan, not an aisle can.
Hardware
Headlamp or flashlight for inspections
German cockroaches, rodent runways, and bed-bug harborages are night-shift jobs. A light you can point into a hinge beats another can of spray.
European hornet vs yellowjacket
Yellowjackets are smaller, brighter yellow and black, and often nest in the ground or a wall with heavy picnic scavenging. European hornets are true Vespa — brown and yellow, cavity nests, sometimes at night lights. Paper wasps build open umbrellas under eaves. Full split: European hornet vs yellowjacket.
Nest-location decision tree and night safety
- Get an ID. Photo to extension if you think “murder hornet.” Vespa mandarinia is a different insect. Established V. crabro in the eastern US is this page.
- Find the entrance at dusk. Traffic into a soffit, barn, hollow tree, or wall. Do not stand in the flight path. Do not poke a cavity with a broom.
- Ground or open eave umbrella?. You may have Yellowjacket or Paper wasp instead. Wrong biology, wrong product placement.
- Cavity in a structure: hire help. Night treatment of voids is how people get hurt and how colonies get driven inward if you seal too soon. After the colony dies, repair in winter. Change bedroom lighting and screens if they batter a window.
When to hire a licensed professional and Exclusion and sealing after the season. Anaphylaxis is emergency care.
Prevention that actually sticks
- Cap hollow posts; repair barn holes in winter.
When to hire a licensed professional
Tree and structure cavities.
United States and Tier 1 notes
Eastern US. In the UK, V. crabro is a native hornet with different cultural status.
Common questions
Is this the murder hornet?
No. That headline referred mainly to Vespa mandarinia. European hornets are established here.
How do I kill European hornets?
You treat a nest, not random workers at a light. Cavity nests are a technician job at night. A swatter war is how stings happen.
How do I get rid of European hornets in a wall?
Keep people away, hire a licensed operator, then seal the void in winter. Sealing a live nest drives them into living space.
