Signs of Rodent Infestation

Rodents are one of the most persistent and costly threats to farm biosecurity. Beyond being a nuisance, they can spread disease, contaminate feed, and cause serious damage to equipment and infrastructure. For any farm, the presence of rodents doesn’t just impact productivity, it can compromise the overall health and safety of the operation.

Why Early Detection Matters

Rodent infestations often start quietly. A few unnoticed intruders can quickly become a widespread issue, leading to contaminated products, animal health risks, and expensive repairs. Detecting the early signs of rodent activity allows for faster, more effective control before the population expands.

Rodents are rarely seen in the open, but they leave behind plenty of clues. Regular inspections and awareness of these warning indicators are your first line of defense.

Common Signs of Rodent Activity

• Droppings
  Small, dark pellets found near feed, storage areas, or along walls often signal active rodent presence. Fresh droppings are soft and shiny, while older ones become dry and dull over time.
• Gnaw Marks
  Rodents constantly chew to keep their teeth trimmed. Look for bite marks on feed bags, cables, wooden beams, and other surfaces. Damaged wiring can pose a fire hazard, so don’t ignore this sign.
• Nests
  Nesting materials often include shredded paper, straw, insulation, or fabric. Check hidden, warm areas such as behind equipment, under flooring, or inside wall cavities.
• Noises
  Scratching, squeaking, or scurrying sounds, especially at night, are common indicators of rodent activity. These noises often come from ceilings, walls, or storage areas.
• Tracks and Smudge Marks
  Rodents follow the same paths repeatedly, leaving greasy rub marks or footprints along walls, beams, and pipes. A light dusting of flour or powder can help reveal their travel routes during inspections.

Take Action

If any of these signs are detected, it’s important to act promptly.

• Inspect regularly: Schedule routine checks around feed storage, livestock areas, and buildings.
• Seal entry points: Rodents can squeeze through openings as small as a coin – close gaps and repair damaged vents or doors using Xcluder^® products, which are specially designed to seal and reinforce openings to block rodents and other pests from getting inside.
• Maintain cleanliness: Store feed securely and remove clutter that provides hiding spots.
• Engage professionals: For ongoing monitoring and control, consider working with a pest management provider familiar with agricultural settings.

A proactive approach to rodent control is an investment in the long-term health of your operation. By recognizing early warning signs and responding quickly, you can prevent contamination, safeguard animal welfare, and maintain a clean, compliant, and productive farm environment.
