Mice are a highly adaptive and invasive species and they’re able to populate a variety of ecosystems. Agricultural fields, buildings, and boats are all viable habitats. In more temperate climates there will be even mor possible nest sites. Swimming, climbing, jumping proficiency, and the two incisors on their upper jaw, all make for a formidable predator wherever they reside. However, despite all of these amazing abilities, the house mouse chooses to reside, as its name would indicate, in a home.

House mice (Mus Musculus Domesticus) are a highly adaptive member of the genus Mus (mouse), yet for some reason they choose to live in the least demanding environment, a human home. They are attracted by the continuous flow off food and warmth, ideal for nest sites. The offer of food and shelter is so tempting that many choose to stay and breed year-round. With an average of six baby mice per litter and a new litter every 20 to 30 days, they reproduce approximately 3 times quicker than brown rats. In fact, a study was conducted where a male (buck) and female (doe) house mouse were placed on a small island with no other competing mice. Within just six months the mice had reached their seasonal carrying capacity, having produced 68 young!

House mice are native to Eurasia due to its temperate climate. Even before Columbus sailed the Atlantic, mice were following us across tundra and rainforest. In fact, the earliest evidence of mice interacting with humans is 15,000 years old, dating back to the hunter-gatherer period.


As one can imagine, the palate of a house mouse is highly adaptable since every habitat they migrate through will hold different opportunities for feeding. Outside dwellers will eat insects and a lot of grain, however, inside dwelling mice are practically omnivorous and, just like brown rats, will consume 10-15% of their body weight each day in just about anything we throw away. Most house mice will nibble on multiple different food sources to obtain their required nutrition, up to 20 times each night, since they’re nocturnal. Despite this voracious appetite, they do not require a frequently available water source since they hydrate sufficiently from solid foods.

A large proportion of a mouse’s 3g daily intake will be grain, namely cereal, favouring high-energy, man-made foods. Studies have proven that the levels of aggression in both rats and mice can be attributed to this high fat ‘human’ diet they have both been on for so long. These foods increase oestrogen levels and results in a shorter temper and longer periods of aggression. Rats and mice used in testing appear to have a longer lifespan than those left to their own devices in the wild where human food, whether in the bin or cupboard, is so readily available.


mouse droppings mouse scratches


3-6 mm long, black and rod-shaped. Approximately 80 droppings per day, often appearing in clusters.

Nest sites

Spotted in various places including attics, storage boxes, floorboards, disused cupboards. Check around fridges, ovens, heating units and washing machines too.

Gnaw marks

Check wood, paper, cables, carpet and furniture for marks.

Smear marks

Dark grey marks on surfaces from oil on hair.


Although they don’t sweat, they emit a musky odour and urinate a lot, producing an ammonia smell.


Hearing pattering feet in walls at night could be a sign of a mouse or rat infestation.

Upset dog

If your dog is barking at night at what seems to be nothing, it could be picking up the scent or sounds of rodents.

Bait & Kill

  • Baiting and killing applies a greater pressure to the rodent population. Our Ultra Power Block Bait kills rats and mice in just one feed to quickly eliminate the source of the problem and ensure there fewer reproduction cycles.
  • All our Bait & Kill stations come with safety precautions including a lock & key feature, designed with the safety of your children and pets in mind to reduce the risk of accidental contact with bait.
  • A lot of rodent bait on the market deteriorates in poor weather conditions. Our All-Weather Block Bait is moisture resistant and remains fresh in damp and wet winter months.

Catch & Kill

  • Catch & Kill traps come equipped with a non-lethal bait which attracts and kills rodents. Individual refills of Mouse & Rat Attractant are also available for a tested and proven way of increasing catch rates.

  • Sonic rodent repellers are a modern addition to the pest control market. They are scientifically developed to emit ultrasonic frequencies, inaudible to the ears of humans and non-rodent household pets, yet loud enough to be unpleasant for target pests. Our Sonic Repellers (STV726/STV728) are simple to use and maintenance free. Plug the device in for 24/7 protection of an area up to 37m2 per unit.
  • Other modes of repelling include our Anti Rodent Sachets and Refresher Spray, containing a 100% Natural Mint Aroma suitable for home and living areas.
  • Our Ultra Power range is scientifically tested and proven to provide high-calibre control of target pests. The Mega-Sonic Twin-Speaker Ultrasonic Pest Repeller (STV725) employs double the ultrasonic power compared to standard ultrasonic repellents, to successfully repel from over 90% of treatment areas. The Ultra Power units protect a wider area than the standard The Big Cheese range of ultrasonic repellents. The Mega-Sonic Plug-In Twin-Speaker Ultrasonic Pest Repeller covers a surface area of up to 60m2. Over 200m2 will be protected by the Mega-Sonic Multi-Speaker 360o Pest Repeller (STV748).

  • Sonic repellents minimise human contact with the pests and makes for a more sanitary solution to your pest problem.
  • Many sonic repellents do not emit high enough frequency to penetrate walls and target the nest, however, our Advanced Pest Repeller pulses through wiring to reach nest sites within walls, ceilings and cavities.

Catch Alive

  • For customers who are averse to killing rodents when dealing with an infestation, more ethical alternatives are available. In contrast to traditional kill traps and poisons, this category captures the pest then permits release into the wild.
  • Our Ultra Power Live Multi-Catch Mouse Trap (STV177) has an all-weather design, a lifetime guarantee, and is able to humanely capture 10 or more mice.
  • With the absence of lethal baits and spring-loaded traps, this method is super-safe to use around children and household pets.
  • When using live catch traps, you should always adhere to the 1981 Wildlife Act by checking traps regularly and storing out of reach of animals when not in use, to avoid prolonging animals’ distress and the accidental trapping of non-target animals or


These are some simple tricks you can implement in your home to prevent a future mouse infestation.

  • As an additional attractant, apply any sweet and sticky food which would be tricky to remove (such as jam or peanut butter) to the trap. On the other hand, you could consider our poison-free Mouse and Rat Attractant (STV163), designed by pest control professionals.
  • Sprinkle flour over rodent tracks, leave for a few days, then check to see if more tracks are present. If so, it is likely you have an ongoing rodent problem.
  • Seal up entry points around and under household appliances, since rodents can gain access to valuable property through unlikely holes: mice can squeeze through holes less than an inch wide.
  • Mice rarely venture further than 20-30 feet from their nest sites so place traps along walls, close to the evidence of a rodent intrusion.
  • Always wear gloves when handling traps or other pest control methods to avoid the transference of human scents onto these; the sensitive noses of rats will easily detect foreign scents in their usual environment.
  • Bird food is not only perfect for squirrels, but mice too. Scrub down your barbeque after use. Purchase secure outdoor containers for pet food.
  • Although neither fool proof nor comprehensive, some cats do enjoy hunting mice and often bring them back into the house as ‘offerings’.

Eliminate food sources

  • Keep food in secure containers. This includes pet food stored outdoors.
  • Scrub down cooking appliances regularly (indoors and outdoors) to remove food debris that can become easily accessible to rodents.
  • Remove bins away from your house and keep lids secured. Avoid letting bins overflow where possible.
