Mouse control in Rosebank flats, offices and houses

Mouse control in Rosebank is mainly a building problem: mice live inside walls, ceilings and service ducts, especially in apartment blocks and offices. We find where they nest and how they move between units, use traps and lockable bait stations to clear them, and show you which gaps to seal so they cannot return.

Why mice are a flats-and-offices pest here

Rosebank and its neighbours have a lot of multi-storey living. Killarney's older apartment blocks, the newer residential towers around the Rosebank node and the converted houses split into units in Parktown and Melrose all share walls, roof voids, plumbing risers and electrical shafts. A house mouse needs only a gap about the width of a pencil, so those shared spaces are effectively a road network. Office blocks add suspended ceilings, cable trays and kitchenettes with a steady supply of crumbs.

Mice also breed fast. A female can produce a new litter every few weeks, so two mice noticed in autumn can become a resident population by midwinter, just as the cold Highveld nights push more of them indoors.

Signs it is mice, not rats

• Droppings like dark grains of rice, scattered rather than in piles, in drawers, behind the stove or along skirting boards.
• Light scratching or rustling inside walls and kitchen units rather than heavy running overhead.
• Shredded paper, tissue or insulation gathered into a nest behind appliances or in the bottom of a cupboard.
• Small, neat holes nibbled in food packaging, especially cereal, pet food and bird seed.
• A musty, stale smell in an enclosed cupboard.

How we deal with mice

In a flat or house

We check kitchen kick-plates, the space behind built-in appliances, the geyser cupboard and where pipes enter walls. Inside we rely mostly on traps placed along the routes the mice use, because mice explore new objects and are easier to trap than rats. Where bait is needed, it goes in lockable stations. We then point out the openings: gaps around pipes under the sink, unsealed holes behind the stove, gaps under doors to the outside.

In an apartment block or office

Treating one unit in a building with shared ducts mostly moves the mice next door. We prefer to work with the managing agent or body corporate on common areas, refuse rooms, service shafts and the units reporting activity, all on the same visit. Offices and commercial kitchens can have a monitoring contract with scheduled visits and a written record of every station.

Getting ready for our visit

Leave droppings where they are so we can read the activity, and clear the space under the sink and the bottom of the pantry so we can see the gaps behind them. If you are in a block of flats, let the managing agent know we are coming; access to the refuse room, the basement and the service shafts often makes the difference between a quick result and a slow one. In an office, a list of which floors or desks have reported mice saves a lot of searching.

The thing that keeps mice around

Food that is easy to reach. Mice need very little, and in offices the culprits are usually desk drawers with snacks, open sugar and coffee in the kitchenette, and bins without lids. At home it is pet food left in a bowl overnight and bird seed stored in its paper bag. Treatment works far faster once these are in sealed containers.

A common mistake

Ultrasonic plug-in repellers. We are asked about them all the time, and the honest answer is that mice quickly get used to them. The other mistake is blocking holes with steel wool alone, which mice can pull apart; fill the gap properly with mortar or sealant over the mesh.

A local tip

If you live in one of the older blocks, check the cupboard where the plumbing stack runs. In many of these buildings the pipes pass through roughly cut holes between floors, and sealing those around your own unit closes the main highway into your kitchen.

What mouse control costs, and why

For a single flat or house, the cost depends on how widespread the activity is and how many visits it takes to clear. For a whole building or an office, it depends on the number of units or floors, the common areas involved and whether you want ongoing monitoring. Our price list for pest control shows the guide prices. If it really is one mouse that came in through an open door, a couple of snap traps from the hardware store will often do the job.
