Did You Know? In Indiana, roof rats—often seen in attics and along trees—are especially adept climbers, making them a persistent challenge for homeowners.

House Mice in Indiana: Silent Home Invaders

House mice (Mus musculus) are prolific breeders that thrive in both urban and rural settings. Their small size makes them difficult to spot until an infestation takes hold.

Signs of Infestation:

• Droppings: Tiny, rice-sized pellets near food storage areas.
• Gnaw Marks: Chewed wires, baseboards, or food packaging.
• Nests: Bundles of shredded material hidden within walls or attics.

Control Tips:

• Seal gaps larger than ¼ inch using steel wool or caulk.
• Store food in airtight containers to eliminate attractants.
• Use snap traps (baited with peanut butter) for humane and effective removal.

Roof Rats: Indiana’s Stealthy Climbers

Roof rats are known for their agility and ability to access high areas, such as attics and tree canopies, making them particularly challenging to control.

Identifying Roof Rats:

• Size & Appearance: Typically 6–8 inches, slender build with a long tail.
• Habitat: Often found in attics, on rooftops, or in trees near homes.
• Behavior: Nocturnal and excellent climbers; frequently contaminate stored food.

Control Tips:

• Regularly inspect your attic and roof areas for signs of nesting.
• Trim tree branches that overhang your roof to reduce access.

Squirrels & Chipmunks: Furry but Destructive

Eastern gray squirrels and chipmunks may appear charming, yet they can cause significant damage when they invade attics or gardens.

Common Problems:

• Attic Damage: Chewed wiring, insulation, and structural materials.
• Garden Losses: Chipmunks and voles can decimate crops and ornamental plants.

DIY Methods:

• Snap Traps: When placed correctly, snap traps can be highly effective for small infestations.
