What should be done if rats have infested an attic? - in detail
Rats occupying an attic require a systematic response to eliminate the infestation and prevent recurrence.
First, conduct a thorough inspection. Identify droppings, gnaw marks, nests, and active pathways. Use a flashlight and mirror to examine hidden corners, insulation, and roof joists. Record all entry points, even those as small as a quarter‑inch opening.
Next, seal every access route. Apply steel wool or copper mesh to gaps, then cover with caulk, expanding foam, or metal flashing. Repair damaged vents, chimneys, and eaves using appropriate hardware. Ensure that all exterior surfaces are free of overhanging branches that could provide a bridge to the roof.
After exclusion, implement a trapping program. Choose snap traps or electronic devices positioned along established runways, near walls, and close to food sources. Bait with peanut butter, dried fruit, or meat. Place traps perpendicular to walls, with the trigger end facing the wall, to increase capture rates. Check traps daily, dispose of carcasses in sealed bags, and reset with fresh bait.
Sanitation follows removal. Remove all nesting material, shredded insulation, and contaminated debris. Clean surfaces with a disinfectant solution containing bleach (1 part bleach to 10 parts water) to eliminate pathogens. Dispose of waste in sealed containers and wash hands thoroughly after handling.
Finally, adopt preventive measures. Store food in airtight containers, eliminate water sources, and keep the attic well‑ventilated to reduce humidity. Install rodent‑proof vent covers and maintain regular inspections, especially after seasonal changes.
If the infestation persists despite these actions, contact a licensed pest‑control professional. Certified experts possess specialized equipment and knowledge for large‑scale removal and can provide a warranty for ongoing protection.
