What to do if rats appear? - briefly
Seal entry points, remove food sources, and deploy traps or call a licensed pest‑control service. Inspect the area regularly to verify eradication and prevent re‑infestation.
What to do if rats appear? - in detail
When rodents are detected in a building, immediate containment is essential. Remove food sources, store perishables in airtight containers, and clean all surfaces to eliminate crumbs and spills. Dispose of garbage daily in sealed bags.
Next, conduct a thorough inspection to locate entry points. Examine walls, foundations, roofs, and utility penetrations for gaps larger than ¼ inch. Seal openings with steel wool, metal flashing, or cement‑based caulk; avoid using soft materials that rodents can gnaw through.
Implement control measures:
- Mechanical traps – snap traps positioned along walls, behind objects, and near suspected runways. Use bait such as peanut butter or dried fruit. Check traps daily and dispose of captured animals promptly.
- Live‑catch traps – cage traps for humane removal, placed in the same locations as snap traps. Release captured rodents at least ½ mile from the property, complying with local regulations.
- Electronic devices – ultrasonic emitters claim to repel rodents; effectiveness varies, so they should supplement, not replace, physical traps.
- Chemical baits – rodenticides placed in tamper‑resistant stations. Follow label instructions, wear protective gloves, and keep stations inaccessible to children and non‑target wildlife. Consider professional application for high‑risk situations.
If infestation signs persist after these steps—continuous droppings, gnaw marks, or audible activity—engage a licensed pest‑control service. Professionals can perform baiting programs, conduct structural assessments, and provide a documented eradication plan.
Maintain long‑term prevention by scheduling regular inspections, keeping vegetation trimmed away from the building, and ensuring exterior lighting does not attract insects that serve as rodent food. Document all actions and monitor for recurrence to verify that the problem remains resolved.
