Roof Rats

What is a Roof Rat?

Roof rats, also known as black rats or ship rats, are a common rodent species notorious for their agility and adaptability. They are often found in warmer climates and coastal areas, but they can thrive in various environments if shelter and food are available. Here's what you need to know about these pests:

Physical Characteristics

• Size: 6-8 inches in body length, with a tail longer than their body (7-10 inches).
• Weight: 5-9 ounces.
• Color: Typically black or dark brown with a lighter belly.
• Features: Large eyes and ears, slender body, and a pointed nose.

Behavior and Habitat

• Climbers: True to their name, roof rats are excellent climbers and often inhabit high places such as attics, rafters, ceilings, and rooflines.
• Nocturnal: Most active at night, they forage for food and build nests during the dark hours.
• Social: Live in colonies and can reproduce rapidly.

Diet

Roof rats are omnivorous but prefer fruits, nuts, seeds, and grains. They will also eat pet food, garbage, and even other small animals if necessary.

Signs of Infestation

• Droppings: Small, dark, and spindle-shaped droppings near food sources or nesting areas.
• Gnaw Marks: Damage to wires, wood, or other materials from their constant chewing.
• Grease Marks: Dark, greasy rub marks along walls or beams where they travel.
• Noises: Scratching or scampering sounds in walls, attics, or ceilings.
• Nests: Found in attics, insulation, or other high areas using shredded materials.

Risks and Concerns

• Health Hazards: Roof rats can carry diseases like leptospirosis, salmonella, and rat-bite fever. Their droppings and urine can contaminate food and surfaces.
• Property Damage: Their gnawing can cause structural damage, increase fire risk by chewing electrical wires, and compromise insulation.
• Infestation Growth: With a rapid reproduction rate, a few roof rats can quickly multiply into a large infestation.

Prevention Tips

1. Seal Entry Points: Close gaps or holes in roofs, walls, and vents larger than 1/4 inch.
2. Eliminate Food Sources: Store food in sealed containers, secure garbage bins, and remove pet food from outdoors.
3. Trim Trees and Vegetation: Keep branches and shrubs away from roofs and walls to limit their access.
4. Maintain Cleanliness: Remove debris and clutter where rats can hide or nest.

Control Measures

If you suspect a roof rat infestation, consider these approaches:

• Trapping: Use snap traps or live traps placed along their pathways.
• Baiting: Use bait stations with rodenticides in areas away from children and pets.
• Professional Pest Control: For large infestations, Mares Exterminating can implement integrated solutions to eradicate roof rats and prevent their return.
