How should I treat a room after rats? - in detail

Begin with a thorough visual inspection. Identify all signs of activity, including gnaw marks, droppings, urine stains, and damaged food packaging. Document locations to prioritize treatment.

Remove all visible debris. Wear disposable gloves and a mask. Collect droppings and nesting material with a sealed bag. Dispose of waste in a rigid container, then place the container in an outdoor trash bin.

Sanitize surfaces. Prepare a solution of one part bleach to ten parts water. Apply to hard surfaces, such as countertops, floors, and walls, allowing a minimum of ten minutes of contact time before rinsing. For porous materials that cannot be adequately disinfected, consider removal and replacement.

Address lingering odors. Use an enzymatic cleaner designed for rodent waste to break down organic residues. Follow manufacturer instructions for dilution and application. After treatment, ventilate the space by opening windows and using fans for at least thirty minutes.

Seal entry points. Inspect walls, foundations, and utility penetrations for gaps larger than two millimeters. Fill openings with steel wool, then cover with caulk, expanding foam, or metal mesh. Install door sweeps and repair damaged screens.

Implement ongoing pest‑prevention measures. Store food in airtight containers, keep trash in sealed bins, and maintain regular cleaning schedules. Consider placing snap traps or electronic devices in concealed locations to monitor any residual activity.

Conduct a final verification. Re‑inspect the area after 48 hours to ensure no new droppings or gnaw marks appear. If evidence of continued presence is found, repeat the sanitation process and reassess sealing effectiveness.
