The common house mouse is usually 6 - 9 cm from nose to base of tail and the tail can be at least double the length of the body at up to 10 cm long.

They are usually light brown and grey and weight less than 25 grams.

Unlike rats they can survive without water obtaining their moisture from food sources. Mice use ultrasound to communicate and have very sensitive hearing.

Mice live in nests and use various materials to form them, usually paper, wool and material, the nests can be found close to food sources and usually within houses or buildings such as in loft spaces, cavities or under floor boards.

Access to houses and buildings can be made through cracks as small as 0.5cm with the mice able to squeeze though.

Mice will eat most food, but prefer cereal products, they are happy to gnaw through most solid objects to reach the food source.

  • Mice are usually most active at night and can be heard running around looking for food, and gnawing to access food and keep their teeth in check
  • Knowing where you hear the noise most at night can help the pest control officer identify the right treatment programme
  • Mice are often noticed in the autumn, when the weather starts to become colder they will seek a warmer home for the winter
  • Mouse droppings may be found close to where the mice are nesting or close to food sources, a single mouse can produce up to 80 droppings a day; these are black, rod shaped and 3-6mm long
  • You may find smear marks where repeated contact with the oils in the mouse fur leaves a dark grey mark on surfaces
  • Nests may be found in loft spaces, around heating pipes or airing cupboards
  • We only treat mice within buildings, sheds, outbuildings and garages. This is to make sure that only mice causing a nuisance are destroyed and not field mice or other non-target species which could be poisoned
  • An officer will visit and carry out a full survey to identify where the mice are living and how they are accessing your property. They will be able to offer you advice on any prevention steps you may need to take, like how to store food or waste materials for example
  • The officer will set up a treatment programme using mice boxes or trays depending on the location of the infestation. It is important children and animals are kept away from the poison and the officer will leave you with health and safety information about the mouse poison A further appointment will be made to visit and assess how much poison has been taken, this is usually 1 - 3 weeks after the first appointment
  • Depending on the treatment needed the officer may visit up to 3 times in total
  • Mice will cause a lot of damage from their gnawing, they are also known to spread diseases such as Salmonella and Listeria which can cause food poisoning
  • Mice breed very quickly and if left untreated will quickly reproduce and can cause extensive damage
  • We are able to offer you a thorough, effective treatment using rodenticides which are not always available to the general public
As part of Wiltshire Councils treatment process we will advise you specifically on how to prevent future pest infestations; however the following advice should always be followed
  • Keep your premises in good repair to prevent mice gaining entrance, mice can get through a hole as small as 0.5cm, in colder weather mice will look for somewhere warmer to live
  • Do not allow outside areas to be become overgrown, keep gardens free from rubbish and tidy
  • Ensure all bins are kept shut and in good order
  • Compost bins should be placed on wire mesh and the lid kept secure
  • Do not overfeed wild birds, all food should be hung in suitable containers and food should not be left on the floor
  • Any pipes leading from the outside to the inside of the building should be sealed to prevent access
  • Ventilation or air bricks should be fitted with wire mesh cover, we are now able to supply and fit these as part of a treatment ask the pest control officer for details.
