Why rodent control fails in warehouses

1 — Stock pushed against the wall

Rodents travel tight against walls, not down the middle of aisles. Stock pushed against the wall gives them a protected run that is never seen or inspected, and leaves nowhere to place bait stations where they belong.

The fix is known and cheap: a half-metre inspection aisle along the internal walls. That alone changes the programme's outcome more than doubling the visits would.

2 — Loading doors

A loading door open through the working day is the first entry point. A gap beneath it the width of a finger is enough for an adult mouse.

Rubber bottom seals and air curtains solve most of it, but that is engineering work, not pest control — which is why the report flags it and the technician does not carry it out.

3 — The waste area against the building

Bins against the warehouse wall mean a permanent food source metres from the stock. However well the inside is treated, the outside keeps feeding the infestation.

The recommended distance between bins and any door or opening is at least ten metres, with tight-fitting lids.

4 — A programme with no documentation

A warehouse is a large space and activity moves around it. Without dated reports compared month to month, nobody notices that activity shifted from the north corner to goods-in — and treatment stays in the wrong place.

Documentation here is not paperwork; it is a diagnostic tool.

In short

Three of the four are inside the warehouse, not with the contractor. Any proposal that never raises these points, or never asks you to act on them, is selling visits rather than an outcome.
