Mice treatment is one of the more affordable pest services, but the real cost picture depends on whether you need treatment alone or treatment plus proofing. Here’s the breakdown.

Standard Mice Treatment

Typical cost: £150–£220

Covers inspection, professional-use bait placement in confirmed activity areas, and typically two to three visits over a few weeks to monitor and adjust.

Mouse Proofing

Cost: from £79–£350

Sealing the entry points mice are using — gaps around pipework, kitchen unit gaps, air bricks, damaged skirting — is what actually prevents recurrence. Treatment without proofing often means new mice move in behind the ones just cleared.

Why We Recommend Both, Not Just Treatment

Treatment reduces current activity; proofing addresses why mice got in at all. Skipping proofing to save money upfront is one of the most common reasons customers end up booking a second treatment months later — the underlying access point was never closed off.

What Changes the Price

• Property size — more ground to cover means more bait points and monitoring
• Number of entry points found during proofing — a single kitchen gap costs less to seal than multiple access points across a property
• Severity — an established infestation across multiple rooms takes longer to resolve than an early-stage single-room issue
• Property type — period properties (see our guide on property type and mice risk) sometimes have more potential entry points than newer builds, which can affect proofing scope

What’s Usually Included

• Full inspection covering kitchen, loft, and likely activity areas
• Professional-use bait, placed safely out of reach of children and pets
• Two to three monitoring visits
• A clear breakdown of identified entry points if proofing is recommended
