Why offices get mice
Offices are warm, quiet at night and full of crumbs. Raised floors and suspended ceilings create connected voids across a whole floor, and cable risers link floors together. Mice can live in these voids without being seen and come out after everyone leaves. Office blocks in Southwark, Waterloo, London Bridge and Canada Water, and older converted buildings on high streets, all see this pattern.
Signs of mice in an office
- Droppings in desk drawers, under kitchen units and around bins
- Nibbled snacks, biscuit packets and fruit left on desks
- Chewed cables and gnawed packaging in stationery cupboards
- Staff seeing mice in the evening or early morning
What we do
- Survey of kitchens, tea points, floor voids, ceiling voids, risers and stores
- Tamper-resistant bait stations and traps in voids and service areas, out of reach of staff
- Proofing gaps around cable entries, pipes and riser openings
- Advice on food at desks, cleaning schedules and waste
- A written report for the facilities manager or building management
Working with your building
In multi-let buildings, mice move between tenants' floors. We can work with your landlord or building manager so common parts, risers and other floors are included. Regular visits under a pest control contract keep the building monitored.
Questions and answers
Can you work out of hours?
We can arrange visits before or after office hours to avoid disrupting staff.
Are bait stations safe in an office?
Yes. We use tamper-resistant, lockable stations placed in voids and service areas, out of reach of staff and visitors.
Our landlord is responsible for the building. Who should call you?
Either. We are happy to work with both and report to whoever needs the records.
