How to Tell If You Have Rats or Mice in Your House
If you have heard scratching in the walls at night or spotted something strange in the pantry, you might be wondering if you have a rodent problem. Rats and mice are common household pests across Adelaide, especially during colder months when they move indoors for warmth, food, and shelter.
The good news is there are some clear signs that can help you figure out what’s going on. The earlier you spot them, the easier they are to deal with.
1. Noises in the Walls or Ceiling at Night
Rodents are most active after dark. If you hear scratching, scurrying, or light thumping sounds coming from your ceiling, roof space, or behind the walls, it is a strong sign of rat or mice activity. Mice tend to be quieter, while rats are heavier and often make louder thuds or gnawing noises.
2. Small Droppings in Cupboards or Along Walls
One of the easiest ways to tell if you have rodents is by spotting their droppings.
- Mouse droppings are small and shaped like a tiny grain of rice or smaller. They brown generally brown colour. Usually found in cupboards, under sinks, storage items or in roof voids,
- Rat droppings are slightly larger, shaped link small jelly beans or bananas. Generally dark brown or black in colour. Usually found in more open areas like garages, sheds, store rooms or roof voids.
You will often find droppings near food, inside pantries, under sinks, or along baseboards where they travel. Fresh droppings are usually shiny and moist while older droppings can become drier and lighter in colour.
3. Gnaw Marks
Rodents constantly gnaw to keep their teeth from overgrowing. Look for signs of chewing on food packaging, furniture, skirting boards, plastic pipes, or electrical wiring. Fresh bite marks tend to look lighter in colour and may appear overnight.
4. Nests Made from Shredded Material
Mice and rats build nests using whatever they can find such as shredded paper, fabric, cardboard, or insulation. These nests are usually tucked away in quiet places like roof cavities, wall spaces, behind appliances, or even under the floorboards.
5. Greasy Smudge Marks or Footprints
Rats and mice often travel along the same routes leaving behind oily rub marks along walls and floor edges. In dusty areas, you might also notice tiny footprints or tail drag marks. If you are unsure, a light dusting of flour overnight can reveal new tracks by morning.
6. Pets Acting Strangely
Cats and dogs can often sense rodents long before we do. If your pet is barking, staring, or pawing at a specific wall or cupboard, there might be movement behind it. Take their behaviour seriously as they might be picking up on something you cannot hear or see.
7. Damaged or Chewed Food Packaging
If you find holes in bags, gnawed cardboard, or food spilled in your pantry, rats or mice may be helping themselves to your supplies. They often target grains, cereals, pet food, and stored snacks even chewing through plastic to get what they want.
What to Do If You Suspect a Rodent Infestation
If you have spotted one or more of these signs, it is time to act. Rodents do not just make a mess but can carry disease, contaminate food, and cause costly damage to insulation, furniture, and electrical wiring.
Store-bought traps or bait may help with a small issue, but if you are seeing regular signs or hearing consistent noises, it is best to call in a professional. A licensed pest controller will inspect your home or business, locate entry points, and provide a safe, long-term solution to keep rats and mice out.
