European hornets, which these will be, are pretty docile unless you really annoy them.
They are dangerous to bees as they predate colonies, but normally avoid humans.
Unless you're a beekeeper with hives nearby or they are genuinely presenting a risk to you and yours, I'd leave them alone.
European hornets get a bad press because they look scary, not because they are particularly dangerous to humans.
Asian hornets, which thankfully are not yet established on the mainland, are smaller and much more aggressive; they can be identified by having a slimmer and darker body than European hornets, plus they have very identifiable bright yellow legs up to the knees. They are are a notifiable insect in that if sighted, you MUST report them:
- Stay away from their nests to avoid group attack, they do not generally sting without provocation.
- Don't run. They can fly faster than you can run and are intrigued by moving targets and consider running a provocation. Crouch low to the ground, stop moving and try to cover your head.
- Giant hornets are excited by bright colours so wear brown or black.
- They are drawn to perfume and aftershave.
- They're also agitated by the smell of alcohol.
- Sightings should be sent with a photograph and location details to [email protected]
- Do not under any circumstances disturb or provoke an active hornets' nest
- The cost of eradication on private land will be met by the Animal and Plant Health Agency, who can be contacted through Defra on the Defra Rural Services Helpline on 03000 200 301. The Helpline is open Monday to Friday, 8.30am to 5pm. There is an out of hours facility on the same number for reporting suspicion of disease in animals. You can also email [email protected].

For the record, this is an European Hornet that I caught in a pheromone trap near one of my hives. I have big hands, so this critter was about 3.5-4cm body length. The thing next to it is a hatched queen honey bee cell.
