How to identify signs of rodent infestations in winter?

April 5, 2026

Quick Answer

Inspect for gnaw marks on wood, plastic, and wires, and look for droppings, nest material, and tracks in the snow to identify signs of rodent infestations. Check for unusual holes or burrows in insulation and walls. Rodents may also chew through insulation and electrical cords.

Signs in Winter Habitat

Winter is the perfect time for rodents to take over your cabin due to the cold weather and lack of food sources. To identify signs of rodent infestations, look for droppings, which are typically 1/4 inch in length and dark brown in color. These droppings can be found near food sources, nesting areas, and along walls.

Identifying Rodent Tracks

Rodents can be identified by their tracks in the snow. Mouse tracks are typically 1/4 inch wide and have a distinctive “V” shape at the front. Squirrel tracks, on the other hand, are larger, about 1 inch wide, and have a more rounded shape. To track rodents, look for small holes or burrows in the snow and follow the tracks to identify the nesting area.

Inspecting for Gnaw Marks

Rodents are notorious for gnawing on wood, plastic, and wires. When inspecting for gnaw marks, look for small, rounded holes or scratch marks on surfaces. These gnaw marks can be found in areas where rodents are trying to access food, warmth, or shelter. Inspect areas around pipes, wiring, and wooden beams, as these are common targets for rodents.
