Answer first

Colour, size, nest position and behaviour can help separate common wasps from European hornets, but avoid approaching an active nest just to identify it.

What to check

  • Observe from a safe distance
  • Use photographs rather than disturbing a nest
  • Remember bees and hoverflies can also look similar

Use evidence, not guesses

Record what you have seen, where it appears and whether the evidence is fresh. Compare the relevant PestDeck pest profiles before choosing treatment.

When to get help

Professional identification is sensible when the evidence is unclear, activity is established or recurring, access is difficult, a business or shared building is affected, or wildlife and safety rules may apply.
