If an exterminator has already treated the unit, the next question is whether the treatment worked and whether the landlord addressed the source. Your record should show that you cooperated with preparation instructions and that pest activity continued afterward.

  1. Save every treatment notice and invoice you receive Keep the pest-control company name, service date, treatment type if disclosed, preparation sheet, follow-up date, and any written recommendations.
  2. Photograph the unit after you prepare it If you were told to clean, empty cabinets, bag clothing, move furniture, or remove food, take photos showing that you followed the instructions before the appointment.
  3. Start a post-treatment log Beginning the day after service, record live pests, droppings, bites, egg cases, or other signs. Note the exact room and time. Separate old evidence from new evidence when possible.
  4. Capture entry points or building conditions Photograph pipe gaps, damaged screens, door gaps, wall openings, trash overflow, water leaks, or other conditions that may support reinfestation. Do not seal or disturb building systems if doing so could be unsafe.
  5. Document missed follow-ups If the pest company recommends a second treatment and management does not schedule it, preserve the recommendation and your follow-up requests.
  6. Keep safe-cleanup rules in mind For rodents, do not sweep or vacuum dry droppings. CDC recommends wet disinfection methods because sweeping or vacuuming can put contaminated material into the air.
