Mice control in Cambridge

Almost every mouse problem is really an access problem. A house mouse fits through a gap of about 6mm — if a pencil goes in, a mouse goes in — and a single female can produce five to ten litters a year. That combination is why removing the mice you can see rarely ends anything on its own.

We are based on Hawkins Drive here in Cambridge and cover Galt, Preston, Hespeler and the surrounding area, seven days a week from 9am to 9pm.

The Cambridge housing stock, and where mice get in

Where you live in Cambridge is a decent predictor of how they are getting in:

• Century homes in Galt and Preston — rubble and stone foundations with mortar that has degraded over decades, plus original service penetrations that were never properly sealed. These properties often have multiple access points rather than one.
• Post-war housing — gaps around gas and water lines, at the sill plate, and under side and garage doors where weatherstripping has worn through.
• Newer subdivisions — people are often surprised, but new builds are not exempt. Utility penetrations, brick weep holes and gaps behind vinyl siding are all common routes, and the surrounding open ground pushes field mice indoors each autumn.
• Semi-rural properties — the edges of Cambridge back onto farmland, which means a reliable annual influx of field mice as soon as temperatures drop.

Autumn is when Cambridge calls spike

Mice come indoors when the weather turns. In this part of Ontario that means late September through November — the first properly cold nights push them from fields, garages and sheds into wall cavities and basements. The mice were nearby all summer; the cold is what moves them in.

If you had mice last winter and did nothing about the gaps, expect them again. The entry points do not close themselves, and mice deposit scent along runs that guide others to the same route.

Signs worth acting on

• Droppings 3–6mm, dark and pointed, usually along walls or in cupboards under sinks
• Light scratching in walls or ceilings, most noticeable at night
• A persistent musky, ammonia-like smell in a confined space
• Shredded insulation, paper or fabric gathered into a nest
• Gnaw marks on food packaging, and small piles of debris in cupboards

Seeing one mouse in daylight generally means the population is large enough that they are competing — mice are nocturnal, so daytime activity is not a good sign.

What we do about it

We inspect the whole perimeter and the interior to find every access point, not just the obvious one. Trapping is placed along the runs mice are actually using, which is why the inspection matters more than the traps.

Then we seal, with materials mice cannot chew: steel wool packed into gaps, hardware cloth over vents, and proper sealant over the top. Expanding foam alone is not sufficient — they go through it. Sealing is the difference between solving it and repeating it next September.

Where there are children or pets in the property we use tamper-resistant stations. We come back to confirm the activity has genuinely stopped.

Mice or rats?

It is worth establishing before treatment, because the approach differs. Mouse droppings are 3–6mm and pointed; rat droppings are 12–18mm with blunt ends. Mice give light scratching high in walls; rats thump and drag, usually lower down, and dig burrows outside. If it is the larger of the two, see rat control in Cambridge.
