Answer first

Recurring activity usually means the source, access route or wider building context has not been fully resolved.

What to check

  • Re-check the identification
  • Map repeated locations and timing
  • Look beyond treatment to proofing and source control

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.
