How do you disinfect a room after a rat infestation? - briefly
First, clear the space of droppings, nests, and carcasses, wash all surfaces with detergent, then apply an EPA‑approved disinfectant (e.g., a 1:9 bleach solution) and let it remain for the recommended contact time. Finally, ventilate the room and discard any contaminated items in sealed bags.
How do you disinfect a room after a rat infestation? - in detail
After a rodent intrusion, eliminate all live animals and carcasses before starting any cleaning. Wear disposable gloves, a mask rated N95 or higher, and eye protection. Remove food, dishes, and any items that can be contaminated; seal them in heavy‑duty plastic bags for disposal or thorough washing.
- Ventilate the area – open windows and doors, run fans to push air outward for at least 30 minutes.
- Dry‑clean surfaces – use a shop‑vac or a broom to sweep up droppings, urine stains, and nesting material. Dispose of the collected debris in sealed bags.
- Disinfect – prepare a solution of 1 part household bleach (5–6 % sodium hypochlorite) to 9 parts water (approximately 500 ml bleach per 4.5 L water). Apply the solution to all hard surfaces, including floors, walls, countertops, and cabinets, using a mop, spray bottle, or sponge. Allow a contact time of at least 10 minutes, then rinse with clean water.
- Treat porous items – for fabric, insulation, or cardboard, either discard or steam‑clean at a temperature above 70 °C. If steaming is not possible, seal the items in plastic for a minimum of two weeks to allow any pathogens to die off.
- Sanitize equipment – soak reusable tools (brushes, mops) in the bleach solution for 10 minutes, then rinse and air‑dry.
- Inspect and repeat – examine corners, crevices, and hidden spots for missed droppings or urine. Re‑apply disinfectant to any areas that show residue.
Finally, set up a preventive plan: seal entry points, store food in airtight containers, and maintain regular pest‑monitoring. This ensures the space remains free of future contamination.
