Released ahead of Rodent Awareness Week (October 19–25), Rentokil’s 2024 State of the Rodent Report highlights a sharp increase in rodent activity across the U.S., with roof rats becoming a growing concern in expanding urban centers. The report links this trend to milder winters, rapid construction, and urban population growth—factors that are creating ideal conditions for infestations in foodservice and food processing environments.

Modern building materials and inadequate waste management are leaving kitchens and food production facilities more exposed. Foam insulation is easily breached by rodents, and gaps in building exteriors provide accessible entry points. Even a single rodent sighting can lead to costly shutdowns, product recalls, and long-term damage to brand reputation.

The Midwest shows the most significant year-over-year increase in rodent activity, with a 76% overall rise. OH and IN saw the steepest spikes, at 275% and 242%, respectively.

Additional findings from the report include:

• Roof rat populations are expanding alongside urban growth. These commensal pests rely on human environments for food, water, and shelter.
• Fast, low-cost construction often results in structural weaknesses that rodents exploit.
• Human migration and urban development can introduce rodents—and new species—into previously unaffected regions.
• Climate change is extending rodent lifespans, with warmer winters allowing for longer reproductive seasons and higher survival rates.

To support prevention efforts, the report offers a three-step checklist for rodent control. With infestations posing serious risks to food safety and operational continuity, proactive strategies remain essential.
