How do you treat an apartment after a rat infestation? - in detail
After a rat problem, the living space must be cleared of health hazards, repaired for structural integrity, and protected against future intrusion.
First, eliminate all live rodents. Use traps or professional exterminators to ensure complete removal. Confirm that no individuals remain by inspecting hidden areas such as wall voids, attics, and crawl spaces.
Second, discard contaminated items. Food, packaging, and any material showing gnaw marks, droppings, or urine stains should be sealed in heavy‑duty bags and removed from the premises. Soft furnishings that cannot be thoroughly cleaned must be disposed of.
Third, conduct a comprehensive cleaning. Follow these steps:
- Personal protection – wear disposable gloves, N‑95 respirator, and disposable coveralls.
- Dry removal – vacuum all surfaces with a HEPA‑rated unit to capture dust and droppings.
- Wet sanitation – wash walls, floors, countertops, and cabinets with a solution of 1 part bleach to 10 parts water. Let the solution remain for at least 10 minutes before rinsing.
- Carpet treatment – steam‑clean or replace carpets that have absorbed urine.
- Ventilation – run fans and open windows to dry surfaces and disperse odors.
Fourth, address structural damage. Inspect for gnaw holes in wiring, plumbing, insulation, and wood. Seal all openings with steel wool, copper mesh, or concrete, then apply caulk or expanding foam to prevent re‑entry. Replace compromised electrical components and repair any broken pipes.
Fifth, implement preventative measures. Install rodent‑proof hardware such as metal flashing around entry points, heavy‑duty door sweeps, and sealed utility penetrations. Keep all food stored in airtight containers, maintain regular waste removal, and eliminate standing water sources.
Finally, schedule a follow‑up inspection. A professional should verify that sanitation standards are met and that no signs of re‑infestation appear within 30 days.
By following these actions, the apartment will be restored to a safe, hygienic condition and fortified against future rodent activity.
