Rats! We have Mice

One of the worst fears for homeowners is playing host to a family of rats or mice. Here are the top tell-tale signs that you have some rodents sharing space in your home.


The first sign of a rodent infestation is usually spotting the droppings they leave behind. Their droppings are small, dark pellets, usually about 3-8mm in length. Look for these along walls, inside cupboards, and under sinks and ovens.

Signs of Chewing

Rats and mice have sets of teeth that NEVER stop growing. This means they have to grind those down on whatever they can get their paws on, including your furniture. If you spot any marks on the feet of your chairs or sofas, take a closer look. 

Also, check for holes chewed through boxes and packets in your pantry. Rodents have been known to chew through plastic containers to get to food sources. 


Rodents will urinate frequently, and their urine has a strong ammonia smell to it. The odour becomes especially strong in enclosed spaces and can linger even after all rodents have been removed.

Unusual Noises

Mice will usually make their home within your walls or under floorboards. They are most active at night, so keep an ear out for scratching and skittering noises they make as they run through your house.

Strange Pet Behaviour

Pets often pick up on rodent activity before humans do. If your pet is whining or barking at seemingly nothing, or scratching at walls or cupboards, they may be trying to get their paws on a rodent in hiding.

Cats have keen senses, particularly when it comes to detecting small prey like rodents. Some signs that your cat may display in response to the presence of rodents include increased alertness, stalking behaviour, vocalising more than usual, pawing at suspect hiding places or simply spending more time prowling around certain areas or your home.


Check dusty areas for footprints and tail marks. Shine a bright torch at an angle to see if the light catches any smudges or paw prints. You can also sprinkle flour or powder along walls to check for tracks the next day.


Mice will make nests from easily shredded material like paper and fabric. Check for nests within wall cavities, ceilings, under floorboards, stoves, and behind fridges. Look for holes they may have chewed through your walls to gain access.
