Rats are in the crawl space; what should be done? - briefly
Identify and block all entry routes, then install baited or snap traps within the crawl space. Engage a licensed pest‑control professional to confirm elimination and prevent recurrence.
Rats are in the crawl space; what should be done? - in detail
Rodent activity in a crawl space demands swift assessment and decisive measures.
First, confirm the presence of rats by identifying droppings, gnaw marks, and nesting material. Conduct a visual inspection while wearing protective equipment to avoid disease exposure.
Next, eliminate access points. Seal cracks, gaps around utility penetrations, and foundation openings with steel wool, metal flashing, or cement‑based sealant. Ensure vents remain functional by installing mesh screens of appropriate gauge.
Implement control tactics:
- Deploy snap traps or electronic traps along walls, near known runways, and at entry points. Position bait—peanut butter, dried fruit, or meat morsels—inside traps.
- If poison is chosen, place anticoagulant baits in tamper‑resistant stations, away from children and pets. Follow label instructions precisely.
- Consider live‑capture cages for relocation, complying with local wildlife regulations.
- Remove food sources by storing waste in sealed containers, cleaning spills promptly, and eliminating standing water.
Sanitation follows control. Remove all droppings and contaminated debris using a HEPA‑rated vacuum or damp cloth. Disinfect surfaces with a solution of bleach (1 part) to water (9 parts).
Finally, establish preventive practices. Maintain a clear perimeter around the foundation, trim vegetation, and store firewood at least 18 inches off the ground. Schedule periodic inspections to detect new incursions early.
When infestations persist despite these steps, enlist a licensed pest‑management professional for comprehensive treatment and ongoing monitoring.
