Factories & Production Lines
Factories are rarely built with pest exclusion in mind. Shield designs programmes around the machinery, the voids and the shift pattern you actually have, and produces the records your customers ask for.
At a Glance
Industrial pest control is a zoned programme for manufacturing and production sites, designed around continuous running and restricted plant access. It combines external rodent control, insect monitoring around plant and lighting, proofing of service voids and penetrations, and scheduled work that fits shift patterns — producing dated records, trend analysis and treatment justification for ISO 22000, FSSC 22000 and customer specifications.
The Problem
The pest pressure is often lower. The access, the heat and the maintenance backlog are what make it difficult.
Monitoring has to happen around production, and some areas are only reachable during a planned shutdown.
Plant rooms, compressors, ovens and wash-down areas create warm, damp harbourage that runs all year.
Every cable tray, pipe run and duct through a wall is an unsealed route unless someone has deliberately closed it.
Guards, bases and cable management offer shelter that cannot be cleaned or inspected on a normal cycle.
Clean rooms, ATEX zones and restricted plant each carry different rules on what can be used and where.
Doors, cladding, roof lights and drainage that have been on a list for months are the entry points.
The Stake
The treatment is rarely the expensive part. The cost sits in everything that happens around it.
A single sighting in a production area can stop a line while the zone is cleared and cleaned. Product made in the affected window may be held pending a decision, and if that decision goes against you, destroyed. On a site running continuous shifts an hour of lost production is rarely an hour of lost output — it is the hour plus the restart, and on some plant the restart is the longer half.
Nobody outside your business can put a figure on that, because it is built from your unit cost, your output per hour, your shift pattern and how long your plant takes to come back up. It is worth doing the arithmetic once, before you need it. What does an hour of lost production ability actually cost you? What does a shift cost? And what does it cost to hold product while a quarantine decision is being made?
Then there is the audit consequence. Evidence of pest activity in a production or storage zone is not a minor finding against most standards. It calls into question whether the prerequisite programme is working at all, which puts the grade at risk rather than one clause. A downgrade is visible to every customer who asks to see your certificate.
For sites supplying retailers the sharper risk is commercial. Supplier codes sit on top of certification, and a pest finding during a customer audit can trigger corrective action demands, a re-audit at your cost, or suspension of supply while the issue is closed out.
None of this is an argument for more treatment. It is an argument for the thing that prevents the sighting — proofing, monitoring, and acting on what the monitoring shows.
The Programme
Written zone by zone against production, plant, storage and welfare, with the controls each area allows set out explicitly.
Visits planned around running hours, shutdowns and maintenance windows, so monitoring is carried out rather than attempted.
Pressure intercepted at the boundary and at drainage, which is where most factory rodent activity originates.
Monitors and electronic fly killers positioned for heat sources, lighting and airflow rather than to a standard grid.
Cable trays, pipe runs, ducts and expansion joints sealed and recorded, with a proofing register maintained across visits.
Every intervention recorded with product, dose, operator and the reason, which is what ISO 22000 and customer specifications assess.
Insect Control
Insect pest management in a factory is a siting problem before it is a treatment problem. The insects follow heat, light, moisture and airflow, and all four of those are decided by the plant rather than by the building.
Which is why a standard grid of units under-detects here. Monitors and electronic fly killers belong where the flight path actually is: near heat-generating plant, along the lit routes insects travel at dusk, away from doors that would recruit from outside, and never above open product or a preparation surface. A unit sited for the socket tells you about the socket.
The species then names the source. Fruit flies mean fermenting residue in drains, under equipment or in returns. Drain and phorid flies mean the film inside a drain or a grease trap, and no amount of treating the room touches them. Blowflies point outside, to waste or something decomposing. Stored product insects point at packaging stores, long-dwell materials and the stock nobody rotates.
Catch data is the output that matters. Counted by unit, by species and by month it becomes a map of where insects are entering and what is breeding them, which is what turns an insect programme into something that shrinks rather than repeats.
The Standards
Pest control as a documented prerequisite programme inside your management system.
GFSI-recognised certification with the evidence discipline global customers expect.
Our Method
The survey works best with a maintenance lead present, because most of what needs closing is already on their list. A field biologist walks production, plant, storage, welfare and the external curtilage, writes the zoned risk assessment, and issues a proofing register that maps each item to a trade and a window. Monitoring runs from day one, positioned around heat and light rather than to a grid, and the first documented trend review lands at ninety days.
AI Pest Management
Factory pest records fail at handover — a recommendation raised on nights, actioned by days, evidenced by nobody. Insectram holds the zoned site plan, the readings, the proofing register and the trend analysis in one place, with each recommendation assigned to an owner and tracked to photographed close-out, whichever shift closes it.
Between Visits
A monitoring programme covers the periods we are on site. Most pest activity begins in the periods we are not.
The sites that stay clear are the ones where production and hygiene staff know what they are looking at and have somewhere to put it. That means knowing the difference between a mouse dropping and a cockroach frass trail, knowing that a propped fire door at the end of a shift is an entry route, and knowing that a sighting goes in the log rather than into a conversation at handover that gets forgotten.
The sightings log matters more than people expect. An auditor reads it as evidence of two things: that your staff are engaged enough to report, and that something happens when they do. A log with entries and closures reads well. An empty log on a site with findings reads very badly indeed.
On a factory the handover is the weak point, because the person who sees it and the person who closes it are rarely on the same shift. That is a training problem and a recording problem, and both are fixable.

Client Feedback
“Shield’s commercial pest control service is impressive. Their technicians are professional and thorough, ensuring our warehouse remains pest-free.”
Warehousing
“Shield’s audit compliance support for our BRCGS certification has been invaluable. Their knowledge of the standards has made our audits much more streamlined.”
Food Manufacturing
“We’ve been using Shield’s Insectram reporting system and it has changed how we manage pest control. Real-time updates and trend analysis keep us proactive.”
Multi-site Facilities
A Shield field biologist will walk production, plant, storage, welfare and the external curtilage, write a zoned risk assessment and issue a proofing register your maintenance team can work from. No obligation, and you keep both documents either way.
A: Typically every four to eight weeks depending on zone risk, with plant and welfare areas often on a tighter cycle than production itself.
A: Yes, and it is usually the right time for the areas that cannot be reached safely while the line runs. Shutdown work is planned at survey.
A: Usually your maintenance team or their contractor. Shield raises, specifies and records them, and tracks each one to evidenced completion.
A: Routine monitoring does not. Proofing and treatment work inside production areas is planned into your maintenance windows or a shutdown, which is agreed at survey rather than negotiated on the day.
A: Your visit history, zoned site plan, trend data and open recommendations are in the portal and can be produced immediately. That is usually the difference between a question and a finding.
A: Yes. The external perimeter, drainage and the building envelope are where rodent pressure is controlled before it becomes an internal problem, which is why the programme is external-first.
