Practical next steps

What to record and check safely

Warm service routes, pipework and adjoining kitchens can connect units, so isolated treatment may not address wider activity.

  1. 01

    Tell management promptly

  2. 02

    Keep a dated sighting record

  3. 03

    Ask whether neighbouring units are affected

  4. 04

    Coordinate access where recommended

When to request an inspection

Arrange professional assessment when signs continue, identification is uncertain, several rooms or units may be involved, or the building has unresolved access or maintenance concerns. Avoid unverified pesticide use.
