Mouse infestations can cause significant issues in both residential and commercial properties in South Wales, leading to potential visits from environmental health authorities if left untreated. Common problems associated with mouse infestations include property damage and health risks. Mice tend to gnaw on cables, electrical wiring, and wooden objects, while their urine and feces can spread diseases such as Salmonellosis and Hantavirus through food contamination.

Signs of a mouse infestation include:

1. Nests: Made of shredded materials, typically found in lofts, cavity walls, suspended ceilings, and enclosed spaces such as behind appliances, under the kitchen sink, or underneath furniture.

2. Footprints: Appear in dustier areas but often won't be spotted other than by a professional due to their nature.

3. Grease/smear marks: Caused by mice rubbing up against skirting/walls and floors. Oily deposits from their fur are left on surfaces as they continually pass over them.

4. Droppings: Mice droppings are typically small (around 3-8mm) and dark. Mice produce up to 80 droppings a day, so there can be huge amounts of them.

5. Strong, ammonia smells: Mice tend to urinate often, and their urine comes with a strong ammonia-like smell.

6. Scratching noises: More likely to be noticed after dusk.
