Mice

Mus musculus

Size and appearance of house mouse, wood mouse and field mouse

House mice are the smallest subspecies of mice in the UK. The usual weight of an adult house mouse is 15-18g. Wood mouse is slightly bigger, averaging 25g in adult. Field mouse is about one and a half time the size of a wood mouse. All of the 3 subspecies of mice are common in urban Glasgow as well as in suburban Renfrewshire and Lanarkshire and in more rural Ayrshire. They may differ in colour but they do look similar. House mice are usually dark-grey to almost black with a pale underside. Wood and field mice are more brown and red in colour. While house mice live almost exclusively indoors and avoid damp and wet environments, the other two subspecies of mice prefer living outdoors, but also in sheds, garages and outbuildings; however, on entering residential buildings, field and wood mice readily adapt to living indoors.

Reproduction in mice

1 litter typically consists of 5-7 young mice but it is not uncommon for litters with 10-12 offspring. Mice are sexually mature in 5-6 weeks. It means mice can start to reproduce as young as 35 days. The gestation period is 19-20 days, meaning a couple of mice can multiply in as little as 3 weeks. Weaning time in mice is about 3 weeks. In practice, having entered your house, a couple of mice can turn themselves into a troublesome pest infestation within a couple of months if you do not take decisive action.

How we control mice (in Glasgow and Ayrshire)

 

There are many pest control methods to control mice, but we only use the legal and effective ones.

 

Here's what we do to eradicate mice from indoors, and how we do it: Our pest control technician will visit your home within (usually) a day of your request. On the initial visit, we will survey your property or the part of it that is affected by mice. If the tell-tale signs indicate mice are present, we confirm the species and assess the severity of the mouse infestation. During the initial survey, we look for holes and gaps that do or may provide access for mice into the building, or into its particular part. The internal areas prone to mouse ingress that we normally inspect are inside utility cupboards, under the sink, behind the cooker, around the central heating pipes, plus around any pipes and the gas boiler, behind the washing machine, under the kitchen units in general, the pantry, storage cupboards, the loft, and the garage (if any). We add an external survey, where it is possible, to determine where mice are entering the house or the flat. At this point of the visit, to comply with the prepared risk assessment, our attending technician may still need to ask you certain questions related to health & safety, such as whether you have pets or small children living with you, etc, before proceeding to make the treatment plan and administering the initial treatment. Tracking dust or gel is deployed to monitor the presence and movements of mice during the treatment. Contact poison (usually a soft foam formulation) is deployed into and around the potential mouse entry points to control as well as to monitor them entering and leaving the treated areas. Edible rodenticide is administered on trays and in tamper-resistant bait stations in line with the risk assessment. We deploy spring-loaded mouse traps where shyness in taking edible rodenticides is likely to occur or has already occurred. Our treatments for mice are usually administered in the kitchen, in storage and utility cupboards, in the loft, the garage, and sometimes also in the living room and bedrooms, varying with the pest ingress and location of mouse entry points and the severity of the mouse infestation you might have. The minimum number of visits to your home is two, but we recommend three or 4 visits to reliably control and eradicate widespread or severe mouse infestations from indoors. If you schedule just one follow-up visit after the treatment, it is usually in 10 to 14 days. If you schedule (optional) extra follow-ups for repeat inspections and treatments, the first follow-up visit can be in 1 week, the second follow-up in 2 weeks, and the third (final) follow-up in 3 weeks. The extra follow-up visits are beneficial for inspecting and maintaining poisons and traps, as well as conducting more rodent tracking to identify which holes and gaps the mice have been using, and removal of accessible carcasses. Tracking can be very useful where mouse proofing follows on mouse control. At this point (or at the initial survey), we would give you a quote for recommended proofing work. The proofing work is ideally done on the extra follow-up visit after a week or on the final visit. On our final visit, we will reassess the mouse situation before removing rodenticides and traps along with accessible carcasses and do optional proofing. Our mouse control treatments can be made child and pet-friendly.

 

Our quotes for eradicating mice indoors and mouse-proofing

(available in Glasgow and Ayrshire)

A visit to survey only

You are welcome to enquire and ask for our opinion and/or advice on your mouse issue. A phone consultation or advice by email are free of charge. A visit by our technician to survey the interior and/or exterior of your property for mice costs £50. You can then get a £20 discount if you book a mouse control treatment within one month of the surveying visit. Note that a survey done on the same visit as the mouse control treatment would cost you nothing.

Eradicating a mouse infestation from the home

The fixed price is £165 for 2 visits*

The 1st visit is for surveying the job, assessing the mouse infestation, and administering our treatment and rodent tracking. The 2nd visit is for an inspection and re-assessment after the treatment. The 2nd (final) visit is usually in 10-14 days after the 1st (initial) visit. This price is based on an average-size 1-3 bedroom residential property and a starting or moderately-advanced (but not severe) mouse infestation. *Please note that treating larger than 3-bedroom properties and/or severe or difficult-to-control mouse infestations costs proportionately more. We recommend you add extra follow-ups for severe or widespread mouse infestations. Where the customer books extra follow-up visits, they usually are in weekly intervals.

 

Add extra follow-up visits for £55 each

Extra follow-ups are for repeat inspections and treatments, to review progress in eradicating mice from indoors and to conduct more rodent tracking. We can also do internal rodent-proofing work, or quote for rodent-proofing work to be completed on the final visit. The customers who book 1 or 2 extra follow-ups can have disinfection or deodorising, or both, done at no extra cost; alternatively, they can choose free rodent-proofing work instead, worth £35 or £70. Payment is due on completion of each extra follow-up visit.

 

The treatment, administered by us, can safely kill in excess of 150 mice that you might have, in just 2 pest control visits. The potential mouse death count can be doubled or tripled by adding 1-2 extra follow-up visits.

 

Exterminating mice in the loft, the kitchen, a garage, or 1 room only

By means of effectively utilising professional-grade rodenticides (which may be combined with snap traps in some of our treatments), we can make your kitchen, the loft, the garage, or any 1 room mouse-free in just 2 visits (10-14 days apart) for £134. An optional extra follow-up visit after 1st week to check the progress of the treatment by inspecting and replenishing rodenticides and tracking dust/gel, or for inspecting and resetting traps would cost an extra £50.

 

Mouse proofing

In our rodent-proofing work, to stop mice from re-entering the treated internal areas, we use mainly steel wool, wired mesh, expanding foam and glue. We can rodent-proof 2 small holes or 1 medium-sized hole or gap for free after completing mouse control (worth £165 or more). (Optional) proofing of more than 2 small holes or 1 medium-sized hole/gap costs £10 for each small hole, £20 for each medium-sized hole, and £30 for each large hole/gap. Mouse-proofing air-vents (air-bricks) with stainless steel mesh (glued over the vent) costs £20 for 1 medium-sized air-vent (air-brick).
