Signs of Rodent Infestation

Rodents are skilled at hiding, but they leave clues behind. Knowing what to look for helps you catch problems early.

• Droppings: Small, dark pellets near food sources or along walls indicate rodent activity. Mouse droppings are about the size of a grain of rice, while rat droppings are larger.

• Gnaw marks: Rodents chew on wood, plastic, and wires to keep their teeth sharp. Fresh gnaw marks look light-colored and clean.

• Nests: Rodents build nests from shredded paper, fabric, or insulation in hidden areas like attics, basements, or behind appliances.

• Tracks and runways: Look for greasy marks or footprints along walls and baseboards where rodents travel regularly.

• Unusual noises: Scratching, scurrying, or squeaking sounds at night often point to rodents inside walls or ceilings.

• Odor: A strong, musty smell can develop in areas with heavy rodent presence.

  
  

Common Rodent Species and Their Habits

Understanding the type of rodent helps tailor detection and control methods.

• House mice: Small, agile, and curious. They prefer cluttered areas and can squeeze through holes as small as a dime.

• Norway rats: Larger and burrowers. They often live in basements, sewers, or outdoor burrows near buildings.

• Roof rats: Sleek and good climbers. They nest in attics, trees, or upper parts of buildings.

  
  

Each species has different food preferences and nesting habits. For example, house mice eat grains and scraps, while Norway rats prefer meat and garbage.

How Rodents Enter Your Home

Rodents exploit tiny openings to get inside. Common entry points include:

• Cracks in foundations or walls

• Gaps around doors and windows

• Open vents or chimneys

• Spaces around pipes and cables

• Damaged roof tiles or eaves

  
  

Sealing these entry points is a key step in prevention.

Effective Detection Techniques

Experts use a combination of methods to detect rodents early:

• Visual inspection: Check common hiding spots like behind appliances, inside cupboards, and in storage areas.

• Use of tracking powder: Non-toxic powders reveal rodent paths by leaving footprints.

• Glue boards and traps: Placed strategically to monitor activity without immediately killing rodents.

• Motion-activated cameras: Useful for identifying species and activity times.

• Professional rodent detection dogs: Trained dogs can sniff out rodents in hidden spaces.

  
  

Preventing Rodent Problems

Prevention is easier than removal. Follow these tips to keep rodents away:

• Store food in sealed containers

• Clean up crumbs and spills promptly

• Remove clutter and debris around your home

• Keep garbage bins tightly closed

• Trim tree branches away from the roof

• Repair holes and gaps in walls and foundations

  
  

What to Do If You Find Rodents

If you detect rodents, act quickly to avoid escalation:

• Set traps or bait stations in areas of activity

• Use rodent-proof containers for food and waste

• Consider professional pest control for large infestations

• Clean and disinfect areas contaminated by droppings or urine

• Monitor regularly to ensure the problem is resolved

  
  

Health Risks Linked to Rodents

Rodents carry bacteria and viruses that can cause serious illnesses, including:

• Hantavirus pulmonary syndrome

• Salmonella infections

• Leptospirosis

• Rat-bite fever

  
  

Avoid direct contact with rodents and their droppings. Wear gloves and masks when cleaning affected areas.
