Rodents like rats and mice can cause significant damage to your home or business if left unchecked. From chewing through wires to contaminating food, their presence is more than a nuisance—it’s a potential health and safety hazard. At Local Pest Controller, we’ve helped countless homeowners and businesses across Cheshire and North Wales deal with rodent infestations. Here are five key signs that might indicate you have a problem with rats or mice.

Common signs of rat and mice infestations
1. Droppings
One of the most obvious signs of a rat and mice infestation is the presence of droppings. Rat droppings are larger, about 1-2 cm in size, while mice droppings are smaller and resemble tiny black grains of rice. You’re likely to find them near food sources, in cupboards, or along skirting boards.
2. Gnaw Marks
Rats and mice have teeth that never stop growing, so they gnaw on wood, wires, and even plastic to keep them trimmed. Look for bite marks on furniture, cables, or structural elements in your home. This isn’t just inconvenient—it’s also a fire hazard if they chew through electrical wiring.
3. Unusual Noises
Hearing scratching or scampering sounds, especially at night? This could be a sign that rats or mice are active in your walls, attic, or under floorboards. Their nocturnal nature makes these sounds more noticeable after dark.
4. Nests
Rodents build nests using materials like shredded paper, fabric, or insulation. Check hidden areas such as behind appliances, in lofts, or in crawl spaces for signs of nesting. If you find a nest, it’s a clear indication of a more established infestation.
5. Tracks and Smears
Rodents often leave grease marks or tracks along the paths they frequently travel. These smudges are caused by the oils in their fur rubbing against walls or surfaces. You may also notice footprints in dusty areas.
