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: Our pest control technician will visit your home within (usually) a day on your request. On the initial visit, he or she will survey your property or its mouse-affected part to confirm the species and to assess severity of the mouse infestation. Holes and gaps providing entry points to mice in the internal areas of likely high ingress are sought. Tracking dust or gel are deployed to monitor presence and habits of mice during the treatment. Contact poison (usually a foam formulation) can be deployed into and around the entry points to control as well as monitor mice entering and leaving the treated areas. Edible rodenticide is laid down on trays and in tamper-resistant bait stations in line with the risk assessment. We can deploy spring-loaded mouse traps where shyness in taking edible rodenticides occur. Our rodenticidal treatments for mice are 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 visits to reliably eradicate your mouse infestation. A survey and treatment are usually done on our initial visit along with mouse tracking. A first follow-up visit is in 1 week and a second (final) follow-up is in 2 weeks from the initial visit. The extra follow-up after a week is good for inspecting and maintaining poisons and traps, plus we can do more of rodent tracking to ascertain which holes and gaps the mice have been using. This can be very useful where mouse proofing follows on mouse control. At this point (or on 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)
Eradicating a mouse infestation from home
The fixed price is £160 for 2 visits*
The 1st visit is for surveying the job, to assess the mouse infestation, and to administer 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.
Add 1 extra follow-up visit for £50
An extra follow-up is for re-inspecting the treated property, our rodenticides and pest control hardware. Also, to review progress to eradicating mice from indoors and to do more of rodent tracking. We can also do rodent proofing or quote for rodent proofing on this visit.
This treatment administered by us can safely kill in excess of 150 mice you might have in just 2 pest control visits. The potential mouse death count can be doubled by you adding 1 extra follow-up visit.
Rarely, you will need more visits for repeat or additional inspections and treatments. If required, they would cost about half-price of the initial treatment plus inspection.
Exterminating mice in the loft, the kitchen, a garage, or 1 room only
By the means of effectively utilizing professional-grade rodenticides (may be combined with snap traps in some of our treatments), we can make your kitchen or the loft mouse-free in just 2 visits (10-14 days apart) for £130. An optional extra follow-up visit after 1st week to check progress of the treatment by inspecting and replenishing rodenticides and tracking dust/gel, or for inspecting and resetting traps would cost an extra £50. We can also help you get rid of mice in a garage or in any 1 room only by administering 1 rodenticidal treatment and 1 follow-up inspection (2 weeks apart) for £100; to add an (optional) extra follow-up after 1 week would also cost £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-size mouse hole or gap for free after completing mouse control. Proofing more than 2 small holes or 1 medium-size hole/gap would cost £10 per each small hole, £20 for each medium-size 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).
