A rodent problem rarely begins with a dramatic intrusion. More often, it leaves a trail of tiny clues that are easy to overlook but can point to bigger risks to building operations and safety. During Rodent Awareness Week, the National Pest Management Association (NPMA) urges building owners and facilities managers to spot the clues early before bigger problems arise.
For facilities managers in commercial and institutional facilities, that means making rodent and pest checks part of routine operations. According to a survey conducted by The Harris Poll on behalf of NPMA, 91 percent of managers in healthcare, hospitality and food businesses agreed that one pest sighting can permanently damage customer trust.
To ensure managers know what to look for, the NPMA highlights six warning signs:
- Droppings. Are typically found near stored food, in cabinets or drawers and under sinks or along baseboards.
- Gnaw marks. Look for chewed packaging or building materials. Rodents also commonly chew on wires that could create fire hazards.
- Nests. Are typically made from shredded paper, fabric, insulation and packing materials in secluded spaces.
- Tracks or rub marks. Rodents can leave dark grease or dirt streaks along walls and floorboards.
- Unusual noises. Listen for scurrying or scratching sounds inside walls, ceilings or overhead storage.
- Rodent sightings. If one is spotted, chances are that it is not an isolated incident.
If one or more of these signs is detected, document where and when it appeared and arrange prompt inspection by a qualified pest management professional. Never dismiss a clue or rely on cleaning alone. Work with the professional on an integrated pest management plan combining sanitation, employee training and routine inspections.
Year-round attention helps managers identify vulnerabilities and respond before activity escalates, protecting facilities and the people inside. For more pest prevention tips, click here.
