What should be done if rats are in a building? - briefly

Seal entry points, remove food and water sources, and place traps or bait stations; then engage a licensed pest‑control professional to inspect, confirm infestation, and carry out eradication measures.

What should be done if rats are in a building? - in detail

Rats in a building require a systematic response that eliminates the current infestation and prevents future entry.

Begin with a thorough inspection. Identify all signs of activity—droppings, gnaw marks, urine stains, and nesting material—and map the locations of each finding. Trace the routes rats use to access the interior, focusing on gaps around pipes, vents, doors, windows, and foundation cracks.

Implement exclusion measures before any lethal control. Seal openings larger than a quarter inch with steel wool, metal flashing, cement, or expanding foam. Install door sweeps and repair damaged screens. Ensure waste containers have tight-fitting lids and that food storage areas are free of spillage.

Deploy control devices. Place snap traps or electronic traps along established runways, positioning bait (peanut butter, dried fruit, or meat) at the rear of the trap to encourage contact. For larger populations, consider multiple‑catch live traps monitored frequently and released far from the premises. If using anticoagulant baits, follow label instructions, secure stations to prevent non‑target exposure, and wear protective gloves.

When infestation severity exceeds DIY capacity, engage a licensed pest‑management professional. Request an integrated pest‑management (IPM) plan that combines chemical, mechanical, and environmental tactics, and verify that the provider complies with local health regulations.

After removal actions, conduct a sanitation sweep. Remove all debris, clean surfaces with a disinfectant solution, and dispose of contaminated materials in sealed bags. Replace compromised insulation and repair any structural damage caused by gnawing.

Establish a monitoring routine. Install motion‑activated cameras or passive infrared sensors near high‑risk entry points. Check traps and bait stations weekly for at least one month, extending the period if activity persists.

Document each step—inspection findings, sealing measures, trap placements, and professional interventions—to provide evidence of compliance for property managers, insurers, or regulatory agencies.

Finally, educate occupants. Communicate the importance of maintaining a clean environment, promptly reporting sightings, and avoiding practices that attract rodents, such as leaving food unattended or storing garbage in unsealed containers. Consistent adherence to these protocols will eradicate the current problem and sustain a rat‑free building.
