Here are some common signs of a mouse infestation:

• Droppings: Mice leave small, dark droppings, resembling rice grains, in areas they frequent.
• Gnaw marks: Look for chewed or gnawed marks on food packaging, wires, and furniture. Mice have a constant need to gnaw to keep their teeth from growing too long.
• Nesting materials: Mice use materials like shredded paper, fabric, and insulation to build nests. Check for these materials in hidden corners or storage areas.
• Urine odor: Mice have a distinctive ammonia-like smell. If you notice a strong, unpleasant odor, it could be a sign of a mouse infestation.
• Scratching noises: Mice are nocturnal, so you might hear scratching or rustling sounds in walls, ceilings, or under floorboards during the night.
• Footprints or tracks: Check for tiny footprints or tracks in dusty areas. Mice have small, four-toed front prints and five-toed hind prints.
• Holes and burrows: Mice create small holes and burrows in walls or insulation for nesting and travel.
• Visible mice: In some cases, you may see mice running around, especially at night.

If you suspect a mice infestation, it's essential to take action promptly to prevent further issues and potential health risks.
