Answer first

Cat fleas are a common household flea, but persistent activity requires attention to the host and the environmental stages.

What to check

  • Check pets with appropriate veterinary advice
  • Vacuum likely resting areas
  • Confirm the insect rather than treating every small jumpy insect as a flea

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.
