How do pests get into a warehouse?
Three routes, and goods-in is the one most sites underestimate.
- Arriving with stock. Stored product insects come in inside pallets and packaging, not through the door. If nothing is checked at intake, you are importing the problem and then treating the building.
- Building gaps. Roller shutter side channels, worn door seals, unsealed pipe and cable penetrations, damaged brickwork, and vents without mesh.
- Doors held open. Loading bay doors propped during a hot afternoon is the most common single cause we record.
Practical fixes that hold: brush seals fitted into the shutter side channels, door sweeps on personnel doors, hard-material sealing on penetrations, and a written goods-in inspection step so intake checks are written down, not assumed.
Keep a 500 mm clear inspection aisle around the perimeter of the racking. Without it, nobody can see the wall base — and that is where the evidence appears first.

What are pheromone traps actually for in a warehouse?
They are a monitoring tool for spotting a trend, not a control method for removing a population. A site relying on them to “catch” its way out of an infestation has misunderstood what they do.
Their value is early warning and location. Catch numbers rising in one zone tell you something is developing and roughly where, well before anyone sees insects in product. That lets you investigate while it is still small.
To get that value you have to count the catch and record it, not just empty the trap. Counts plotted over time against an action level are exactly the trend analysis an auditor is looking for.
Rules that matter: position them consistently so the counts can be compared, replace lures on schedule, and never place them where they draw insects toward open product.

When is fumigation the right answer for a warehouse, and when is it not?
Fumigation is for treating an infested commodity or a sealed space. It is not a routine hygiene measure, and it does nothing to stop the problem returning.
It fits where there is a confirmed infestation within a commodity, where the space can genuinely be sealed, where export or receiving requirements call for it, and for container treatment.
It does not fit as a scheduled preventive routine, in a space that cannot be properly sealed and cleared, or as a substitute for proofing and goods-in control. Fumigate a building with an open loading bay and the same insects arrive again with the next delivery.
It is also a controlled operation with real safety requirements — sealing, exclusion of people, and a clearance check before anyone re-enters. Clearance is a measurement, not a judgement call. Any provider treating it casually should not be doing the work.

Can we use rodent bait inside a food warehouse?
Standard practice is no. Bait belongs in tamper-resistant stations outside the building. Inside, control should be non-toxic.
There are two reasons, and both matter to an auditor.
First, contamination. A rodent that takes bait and then dies inside the building creates its own problem, often somewhere you cannot reach, near stored product.
Second, the standards expect it. BRCGS and AIB both look for internal control to be non-toxic wherever food or packaging is stored.
What to use inside instead: non-toxic monitors, snap traps, and proofing work that stops them entering at all. The external station line does the killing; the internal devices tell you whether anything got past it.

How do we control stored product insects in a rice or flour mill?
Through stock rotation, cleaning down residues, and monitoring — not through repeated treatment of the building.
Stored product insects live and breed inside the commodity, so a spray around the walls never reaches them. Control comes from four things:
- Strict FIFO rotation. Old stock at the back is where infestations start and stay hidden.
- Residue removal. Spillage in machinery, under racking and in floor joints is a permanent breeding reservoir. This is the step most mills skip.
- Goods-in inspection. Most infestations arrive with a delivery, not through a door.
- Pheromone monitoring — counted and recorded, so you see a rise early and know which zone it is in.
Fumigation has a place for a confirmed infestation in a sealed space or commodity, but it is a reset, not a programme. Without rotation and cleaning, the same insects return.
Activity climbs through the warmer months, so tighten inspection from about June.

How do we keep birds out of a warehouse?
By closing the openings and removing the roosting points. Birds in a food or packaging store are a contamination finding, not a nuisance.
Droppings on stock, racking and floors are the immediate problem, and nesting material blocks gutters and gives insects somewhere to live.
What works:
- Close the way in — roller shutters not left open, mesh on vents and roof openings, gaps in cladding repaired
- Remove roosting points — proofing on ledges, beams and rafters inside
- Remove the attraction — spilled grain and product cleared, waste covered, standing water fixed
- Strip nesting material and clean the fouling properly
The most common cause is straightforward: the loading bay door propped open through a hot afternoon. Fixing that habit costs nothing and solves more than any device.

How should stock be arranged so pests can be spotted?
Leave a clear inspection aisle around the perimeter and keep everything off the floor and away from walls. If nobody can see the wall base, nobody can find the problem.
The working rules:
- 500 mm clear perimeter aisle around the racking, kept empty
- Pallets off the floor and never pushed against a wall
- FIFO rotation — old stock at the back is where infestations start and stay hidden
- Nothing stored directly under racking where it cannot be seen
- Damaged and returned stock quarantined, not left in a corner
The aisle is what auditors check first, because it decides whether monitoring is even possible. A warehouse with stock against the walls cannot demonstrate control regardless of how many devices are installed.
It also makes your own staff checks meaningful, which is where most early findings actually come from.

How is pest control handled in cold storage?
Cold slows insects but does not stop the problem. The risk moves to the warm edges — loading bays, ante-rooms, door seals and the plant room.
Inside the cold chambers themselves activity is minimal. The places that matter:
- Loading bays and dispatch — doors open repeatedly, temperature swings, and this is where most product exposure happens
- Ante-rooms and corridors between chilled and ambient areas
- Door seals and strip curtains — damaged seals are both an energy loss and an entry point
- Condensate and drainage — standing water under evaporators
- Plant rooms — warm, quiet, and usually unassigned
Rodents are the main concern rather than insects: they follow warmth, and gnawed insulation or cabling in a cold store is expensive well beyond the pest problem itself.
Monitoring devices need positions that stay readable in low temperatures, and records still have to satisfy the same audit standards as an ambient warehouse.

Do you handle container treatment for export shipments?
Yes. Container and commodity treatment for export is a defined job with defined paperwork, and the paperwork is usually what the buyer is actually asking for.
Where it applies: destination countries or buyers requiring treatment before goods are accepted, commodities with a confirmed infestation, and shipments where a certificate has to accompany the consignment.
What the job involves: the space sealed properly, people excluded for the full stated period, a clearance check before anyone re-enters, and documentation issued in the form your buyer or agent requires.
Clearance is a measurement, not somebody deciding it smells fine. Any provider treating that casually should not be doing the work.

What about textile, paper and packaging storage?
Different pests from a food warehouse, and the damage is to the stock itself rather than to hygiene compliance.
What attacks what:
- Textiles and natural fibres — clothes moths and carpet beetles. Larvae do the damage, and it is often found only when an order is picked.
- Paper, card and packaging — silverfish where it is damp, and termites where cartons sit against an outside wall or on the floor.
- Rodents — shred packaging and stock for nesting material, and gnaw cabling.
Controls that matter here: humidity management, because damp drives most of it; stock off the floor and away from walls; a clear inspection aisle; FIFO rotation so nothing sits untouched for years; and monitoring positioned where damage would appear first.

How many monitoring devices does a warehouse need, and where?
Spacing follows risk, not floor area. An auditor checks that the layout is justified and that the map matches what is on site.
| Device | Typical placement |
|---|---|
| External bait stations | Around the perimeter, roughly 15–30 m apart, closer near waste and openings |
| Internal rodent monitors | Along internal walls, roughly 10–15 m apart, non-toxic where food or packaging is stored |
| Insect light traps | Away from external doors, never above open product, at a height that can be inspected |
| Pheromone traps | By zone, positioned consistently so counts can be compared over time |
Two rules that decide whether any of it works: every device numbered and on a current map, and a 500 mm clear inspection aisle around the racking. Without the aisle nobody can see the wall base, and monitoring becomes decorative.
Count the catch rather than emptying it. Numbers over time are the trend data an auditor asks for.

We found insects in a batch of stock. What now?
Isolate it before it spreads, then work out whether it arrived with the delivery or came from the building. The answer changes what you fix.
Immediately:
- Quarantine the affected batch — move it away from other stock, do not open more of it than necessary
- Check neighbouring pallets and anything from the same delivery or supplier
- Record it — batch, supplier, date received, what was found, where
- Check your monitoring data — a rise in that zone beforehand points to the building; no prior rise points to the delivery
- Notify the supplier if it arrived infested, and tighten goods-in checks
- Decide on the batch — reject, treat or dispose, and document the decision
Do not simply move it to another part of the warehouse. That is how one pallet becomes a site-wide problem.
Close it out properly: cause, action, verification, date. An auditor will read this exact entry.
