What to do if…
a wasp or hornet nest is forming near a door or window you need to use

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy UK guide

Short answer

Stop using that door or window if you can, keep people and pets away from it, and arrange pest control rather than disturbing the nest. If someone is stung and has breathing trouble, swelling of the lips, mouth, throat or tongue, sudden confusion, severe dizziness, or faints, call 999.

Do not do these things

  • Do not knock the nest down, poke it, hose it, spray it at close range, or try to break it open.
  • Do not block or seal the active entry point while wasps or hornets are still using it.
  • Do not use smoke, petrol, fire, or improvised chemicals near the nest.
  • Do not stand in the insects’ flight path, especially near a single gap, air brick, soffit, vent, frame, or wall crack.
  • Do not swat at wasps or hornets as you pass; move away calmly.

What to do now

  1. Stop using that door or window if you can. Use another entrance, keep the window shut, and avoid leaning out to look.
  2. Make a temporary no-go area. Keep children, pets, visitors, and anyone with a known sting allergy away from that side of the door or window. Put a clear note on the door so nobody opens it by habit.
  3. Watch only from a safe distance. Look for the exact place they keep entering and leaving, such as a frame gap, air brick, soffit, eaves, vent, wall crack, shed edge, or roofline. Do not get close to identify the species.
  4. Arrange pest control through the right route.
    • If you rent or live in a shared building: tell your landlord, agent, housing provider, freeholder, or building manager in writing that a wasp or hornet nest is affecting safe access.
    • If you own the home: check whether your local council provides pest control, or book a qualified pest controller.
    • In England and Wales: you can use GOV.UK to check council pest-control options by postcode.
    • In Scotland or Northern Ireland: council or local authority services vary, so check your local authority website or use a qualified pest controller.
  5. If you must pass before help arrives, reduce the chance of a sting. Wear long sleeves, long trousers, and closed shoes; have keys ready before you approach; keep sweet drinks and food away from the doorway; move through calmly without stopping.
  6. If someone is stung, use the right level of help.
    • Call 999 if there are signs of a severe allergic reaction, including breathing difficulty, swelling of the lips, mouth, throat or tongue, sudden confusion, severe dizziness, collapse, or fainting.
    • Use NHS 111 online or by phone, or ask a pharmacist or GP, if symptoms are worrying but not a 999 emergency, such as worsening swelling, multiple stings, a sting in the mouth or throat, or symptoms that are not improving.

What can wait

  • You do not need to identify whether it is definitely a wasp, hornet, bee, or another insect right now.
  • You do not need to choose DIY chemicals, gadgets, traps, or sealants today.
  • You can wait to seal gaps, repair frames, fit screens, or do longer-term prevention until the nest has been treated and is inactive.

Important reassurance

A nest near an entrance can make an ordinary doorway feel unsafe very quickly. The safest first move is not to solve the whole problem yourself, but to reduce contact, avoid provoking the insects, and get suitable help arranged.

Scope note

These are first steps only to reduce sting risk and keep access as safe as possible. Later decisions about treatment, removal, repairs, or proofing may need a qualified pest controller, landlord, building manager, or other specialist help.

Important note

This is general information, not legal, medical, pest-control, housing, or other professional advice. If someone may be having a severe allergic reaction after a sting, treat it as a medical emergency and call 999.
