Pest Control – Mice

What do they look like?

Mouse

Mouse

The house mouse is light brown to grey in colour and body length varies between 60-90mm, the tail can add an extra 100mm. The droppings are black and rod shaped, measuring 3-6mm. The maximum reproductive potential of a pair of mice and their young in one year is 2,000.

Where do they live?

  • The house mouse normally lives indoors and prefers dry nesting locations. Nests are built wherever there is access to a good source of food

  • Mice often build their nests in spaces under floors and in lofts

  • Mouse holes are normally 20-30mm in diameter

  • Mice are mainly active at night and can often be heard running around in search of food

  • Mice can squeeze through gaps as small as 5mm

What do they eat?

Their favourite foods are cereal products but they will eat almost anything. Mice foul food with urine and droppings. Mice will gnaw their way through wood to get to sources of food.

Why are they a pest?

  • Mice may carry diseases that can be transmitted to humans

  • They can foul and contaminate foods

  • They can cause damage by gnawing wood, cables and pipes (if you suspect you have mice you should ensure you have at least one smoke detector fitted in accordance with the manufacturers instructions)

What are the signs of infestation?

  • Droppings—black rod shaped between 3-6mm

  • Nests—usually made out of wool and paper

  • Gnawing—of furniture or food containers/packages

What can I do to prevent an infestation?

Hygiene

Poor hygiene provides the ideal environment for mice to live and breed in. You should avoid spilt foodstuffs or scraps littering floors, shelves, units or work surfaces.

Where possible, keep food in mouse proof containers.

Proofing

Mice can squeeze through very small openings (5mm). They often find access to houses through air-bricks, spaces around gas, water and waste pipes, electric cables or under ill-fitting doors.

All holes should be filled in, air-bricks and ventilators should be covered with a fine mesh gauze. Attention to holes above ground level is also required as mice can climb rough surfaces. Always carry out proofing measures after an infestation is destroyed.

How can I get rid of mice?

The Council currently provide a free service for the treatment of mice in domestic premises. Pest control officers may survey the premises and may then use poison bait in suitable locations. Contact the Public Protection Department on 01656 643260.

You can treat for mice yourself using the following methods.

Trapping

Old-fashioned break back traps can be effective. The traps can be bought from most hardware stores and garden centers. For best results, several traps should be used. The traps should be placed at right angles to the wall that the mice are running along.

Use cereals or chocolate as bait. Please set traps where young children cannot reach them.

  • Always read the instructions on the product’s label

  • Re-set traps daily until no more mice are killed

  • The advantage of trapping is that dead mice can be collected and disposed of either by burning, burying or flushing down the toilet

Poisons

There are several mouse poisons available from hardware stores and garden centers that give excellent results if used correctly. The manufacturers instructions must be followed for safe use.

  • When laying poisons, ensure that no child or pet can reach the bait

  • All the poison must be removed at the end of treatment and be burnt or buried
