Remove the food, treat the population, then seal the gaps — and with mice the sealing is not a nice-to-have. It is what stops you doing all this again next winter.
Remove the food, treat the active problem, then seal the entry points. Professional treatment is £190 for a flat and £240 for a house; proofing is £180.
Mice differ from most pests in one respect: the proofing is at least as important as the treatment, because the gaps they use are so small that they are otherwise never found or fixed.
Mice need remarkably little. Crumbs behind a toaster sustain activity indefinitely, and a mouse drinks little enough that water is rarely the limiting factor.
Mouse droppings and urine should be cleaned up, but not by dry-brushing or vacuuming, which puts particles into the air. Dampen with a disinfectant solution, wipe with disposable cloths, bag them, and wash your hands.
Rodent droppings can carry organisms that cause illness. That is a reason for sensible hygiene rather than alarm.
Mice are curious rather than wary — unlike rats they investigate new objects readily, which is why traps can work. Two things usually defeat a householder anyway:

View Mouse Control Harrow →With most pests this is the optional final step. With mice it is the difference between solving the problem and repeating it annually.
The gaps are small enough that nobody notices them until something uses them. The usual routes:
Proofing is £180 for up to one hour. Two practical notes if you tackle any of it yourself: identifying which gaps matter is most of the skill, and expanding foam alone is not proofing — mice chew straight through it, so it needs a chew-resistant material behind it.
Read nextMouse Proofing Harrow – What Does the £180 Service Cover? →Do not seal while mice are still inside. A mouse shut into a kitchen void gnaws at whatever is nearest, which in a kitchen frequently means cabling.
In a house, a large share of the population is often in the loft rather than the kitchen where the evidence appears. Insulation makes ideal nesting material and cable runs provide the route down.
If you have mice in the kitchen and have not looked in the loft, look — and mention what you find when you book.
Treatment throughout Harrow and every surrounding area at the same published prices:
It depends on how established the activity is. Ask us about your situation and we will set the expectation honestly.
Throw away anything with gnaw marks or droppings on or near it, and anything in breached packaging. Sealed tins and jars are fine once wiped.
If the gaps are still open, eventually yes. That is what step four is for, and why we push it harder on mice than anything else.
Something else needing attention? Wasp nest treatment across Harrow is £90 fixed cost with our guaranteed service.
Remove food sources, clean carefully, treat the active population, then seal the entry gaps — in that order.
The gaps they use are tiny and never otherwise noticed or fixed, so a treated property with no proofing frequently has mice again within a year.
£190 for a flat and £240 for a house.
No. Seal after treatment, or you shut mice inside the structure.
No. Mice chew through foam — it needs a chew-resistant material behind it.
Usually placement. Mice travel along edges and walls, not across open floor.
Better not to. Dampen with disinfectant first and wipe up with disposable cloths.
Yes. In a house a large share of the population is often in the loft while the evidence appears in the kitchen.
