How To Know If You Have Rats Or Mice

Scratching in the walls, droppings under the sink or strange smells can all mean one thing – rodents. But how do you tell the difference? Many homeowners ask us how to know if you have rats or mice? Although both cause similar problems, there are key differences worth knowing.

Signs to tell rats and mice apart

When it comes to rats or mice, size is usually the most obvious clue. Mice are much smaller, usually 6 to 9 cm in body length. Rats are larger, reaching up to 25 cm long with thick, scaly tails. This is only helpful, however, if you have seen them. More likely you have just had signs.

Droppings help too. Mouse droppings are small, about the size of a grain of rice. Rat droppings are longer, thicker and often found in clusters. Because both animals are nocturnal, you’ll rarely see them during the day. Instead, look for greasy smear marks along skirting boards or gnawing on food packaging.

You may also notice the sounds they make. Mice tend to scratch lightly and move quickly. Rats are heavier and louder, often thudding as they move between walls or under floors. If you’re unsure whether you have rats or mice, check (safely) any entry points. Mice can squeeze through gaps as small as 6 mm. Rats need about 15 mm but can gnaw their way through tougher materials.

Smell can also be a giveaway. Rats have a stronger, musky odour, especially when nesting in numbers. If you notice new smells along with noise or damage, take action quickly. Early identification helps prevent long-term damage and health risks.

What we do to identify and treat them

We always start with a full inspection. This helps us find out whether you have rats or mice, where they’re nesting and how they’re getting in. We check droppings, gnaw marks, smear trails and entry holes. We also look for food contamination and damage to insulation, wiring or stored items. We offer a comprehensive rodent control service in Kent, not just a half- done job!

Once we confirm which rodent is present, we create a tailored treatment plan. We use traps, bait stations and professional-grade proofing materials. All our work follows UK pest control regulations and we always prioritise safety for pets and children.

After treatment, we advise sealing all entry points with mesh, cement or steel wool. We also suggest storing food in sealed containers and keeping rubbish bins secure. Even simple changes like clearing clutter and fixing leaks can reduce the risk of future problems.
