Rats & Mice

Effective rat control in Ammanford, Swansea and more

Have rats inhabited your domestic or commercial property in Swansea, Carmarthenshire or South West Wales? At B Firm Pest Control Ltd, we have many ways of getting them to leave. We can also give you expert advice on how to keep your home rat and mouse free.

House mouse

Description: small rodent with grey/brown fur usually less than 90 mm in total length and weighing less than 20 grams. Colour is generally uniformed with the belly being slightly lighter and the tail typically about 75% of the length of the body.

Biology: mice are omnivorous and are good at adapting to local environments, but generally in rural environments, they eat cereals, seeds, etc. where they consume an average of 2-3 grams of food per day. Whilst they will drink free water, they can in many cases survive without it, obtaining sufficient moisture from their food. Mice will typically live up to 1 year, reach sexual maturity in 6 weeks and can have as many as 8 litters per annum with the average litter size being about 5.

Control: as mice feed at numerous places, the key to successful control is to have a large number of baiting points. Baits containing anticoagulants are generally effective, with a variety of formulations available, including whole grain, blocks and pastes. Traps can also be an effective method of control to quickly reduce large numbers of mice and proofing / housekeeping should be considered to offer a long-term solution.
common rat

Common rat

Description: large rodent which can measure up to 40 cm in length (including the tail). Fur colour can vary but is generally dull grey in colour.

Biology: rats are omnivorous, and whilst they generally feed on cereals and grains, if hungry they can take small chicks and eggs. One of the main characteristics of rats is that they are neophobic – very wary of anything new and they can take 4-5 days before they except a new object into their environment. They prefer small-enclosed spaces and get around by smell and touch. They like to be up against something as they travel like a wall or pipe. Contrary to popular beliefs regarding rats being dirty, they are in fact very clean animals and spend up to 20% of their time grooming. They are however carriers of a number of diseases, the most publicised of which is Weils Disease, which can be fatal to humans. Rats take between 2 and 3 months to reach sexual maturity and can have up to 7 litters per year with the average litter size being about 8. The other UK rat is the ship rat or black rat, which is now very rare and restricted to a few localised port sites.

Control: in contrast to mice, rats tend to have only a few feeding sites and so the key to successful control is to ensure there is a good quantity of bait available (sub-lethal doses can affect the level of control, which will be achieved longer-term). Whole grain bait is the most commonly used, and active ingredients such as Difenacoum and Bromadiolone can be used indoors and out. Rat burrows can be baited directly if safe to do so, and trapping and use of gassing compounds such as aluminium phosphide (professionally trained operators only) can be considered.
wood mouse

Wood mouse

Description: slightly larger than the house mouse with a proportionally longer tail - on average the same length as the body. Wood mouse has light brown fur with a distinctive pale belly and characteristic large ears and bulging eyes. It is also known as the long-tailed field mouse.

Biology: wood mice have a similar life cycle and nutritional needs to the house mouse. Generally, wood mice are found outdoors, entering houses and outbuildings for shelter and food but nesting in the open for much of the time whereas the house mouse, given sufficient resources, will more readily complete full generations without leaving the house or building that it’s living in. The wood mouse is similar to another typically outdoor mouse, the yellow-neck mouse, which can be distinguished by a band of yellowish fur around the neck.

Control: as the wood mouse is largely an outdoor pest, we would only advise control if the mice are entering buildings or causing damage. Control of the wood mouse is the same as that of the house mouse, and a combination of traps and chronic (slow working) baits such as anticoagulants should be effective. Again proofing of gaps to deny entry should be considered to try to prevent or restrict infestations.
