Warehouse pest control usually involves a combination of prevention, monitoring and, where needed, treatment. In warehouses, access points are often the main challenge because doors, loading bays, and goods-in areas need to remain usable throughout the working day.
This can make it easier for flies, insects, birds and rodents to enter, especially during warmer months or at sites that handle food, packaging or stored goods. The table below compares common warehouse pest control measures and where each option is most useful.
Compare warehouse pest control options.
There is no single pest control measure that works for every warehouse. The right approach depends on the building layout, the goods stored, how often doors are opened, and whether the site handles food, packaging, waste or temperature-sensitive stock.
Most warehouses need a layered approach rather than one standalone measure. Physical barriers can help reduce access through doors and loading bays. Cleaning and waste management reduce the conditions that attract pests. Monitoring helps identify activity early, while professional pest control may be needed for an active infestation, a recurring pest issue, or a compliance requirement.
Why busy warehouse doorways are a common pest-control weak spot
Warehouse pest control often depends on how well access points are managed. Doors, shutters and loading bays are necessary for daily operations, but they can also create regular openings for pests to enter.
Open roller shutters and loading bays are common risk points because they are often left open for extended periods during deliveries, dispatch, or stock movement. Even when a door is only open briefly, repeated use throughout the day can make it easier for flying insects, birds or rodents to get inside.
Goods-in and goods-out doors can also be difficult to manage because they are high-movement areas. Pallets, cages, trolleys and forklifts may pass through regularly, so doors may be opened frequently or left open for convenience.
Staff entrances and waste routes can create similar issues. If doors are propped open, bins are positioned close to entrances, or waste is moved through the same access points throughout the day, pests may have more opportunities to enter the building.
This becomes more of a concern in warm weather, when flying insects are more active, and warehouse doors are more likely to be left open for ventilation. Sites handling food, packaging, waste or stored goods may need to pay particular attention to these routes.
What pests are warehouses trying to prevent?
The pests most likely to affect a warehouse depend on the goods stored, the condition of the building, nearby waste areas, and how often doors and loading bays are opened.
Common warehouse pests include:
Flies and flying insects, which are often found around open doors, loading bays, waste areas and food-handling spaces.
Moths can affect warehouses storing textiles, dry goods, grains, or food ingredients.
Beetles and stored-product insects, which are often linked to food, flour, cereals, animal feed, seeds and similar stored goods.
Cockroaches are usually associated with warm, sheltered areas where food residue, moisture or waste is present.
Rodents, including rats and mice, can enter through small gaps around doors, shutters, pipework, drains or damaged building fabric.
Birds, particularly pigeons and gulls, can enter through open doors, roof gaps or loading bays.
PVC strip curtains vs fly screens for warehouse pest control
PVC strip curtains and fly screens can both help reduce pest access, but they are usually suited to different types of openings.
For larger warehouse doors or loading bays, PVC strip curtains are often more practical because they allow movement through the opening without fully exposing it. For smaller openings, such as windows or pedestrian access points, fly screens may be more suitable, especially when ventilation is needed.
PVC strip curtains can also help control temperature by limiting airflow between spaces. This can be useful when a warehouse connects to a chilled area, a food storage room, or a temperature-sensitive workspace.
They may reduce pest access at frequently used doorways, but they do not completely seal an opening and should not be treated as a replacement for cleaning, monitoring, or professional pest control where required.
Warehouse pest prevention checklist
A warehouse pest prevention plan should focus on reducing access, reducing attractants and identifying pest activity early.
Inspect loading bays and roller shutters. Check whether doors are left open for long periods and whether shutters close properly.
Check gaps around doors, vents, pipes and drains. Small gaps can provide access for rodents and insects, especially around damaged frames, vents, pipework and drainage points.
Fit physical barriers where doors are regularly open. Where doors need to remain accessible during working hours, consider whether PVC strip curtains, fly screens, or door seals are suitable for the opening.
Keep waste areas away from entrances where possible. Bins, food waste and packaging waste can attract pests, especially when placed close to warehouse doors or staff entrances.
Clean spills quickly. Food residue, liquids and standing water can attract insects, rodents and birds.
Rotate stock regularly. Older or undisturbed stock can create hiding places and may make pest activity harder to spot.
Inspect pallets, racking and quiet corners. Check behind racking, under pallets, in roof voids and around areas where packaging or unused materials are stored.
Train staff to report signs of pest activity: droppings, gnaw marks, damaged packaging, insect activity, bird fouling, nesting materials, or unusual smells.
Use monitoring or professional pest control for high-risk sites. Warehouses that handle food, pharmaceuticals, packaging, or hygiene-sensitive goods may need regular monitoring and documentation.
When should a warehouse use a professional pest control company?
Physical barriers such as PVC strip curtains, fly screens, and door seals can help reduce pest access, but they are not a treatment for an active infestation. If pests are already present, the site should be assessed by a qualified pest control professional.
A warehouse should contact a pest control company if there are signs such as droppings, gnaw marks, damaged packaging, contaminated stock, nests, insect activity, bird fouling or unusual smells. Recurring sightings near loading bays, waste areas, drains, staff entrances or storage zones should also be investigated.
Professional assessment is especially important in warehouses that handle food, packaging, pharmaceuticals or hygiene-sensitive goods. In these settings, pest activity can affect stock condition, audit outcomes and site hygiene procedures.
Choosing the right doorway barrier for pest-prone warehouse areas
The right doorway barrier depends on the size of the opening, how the doorway is used, and what the surrounding area needs protection from.
Use the following points as a specification checklist:
Doorway size: wider or taller openings may require wider, thicker strips or greater overlap.
Traffic type: pedestrian, trolley, and forklift routes place different levels of pressure on a doorway barrier.
Food or hygiene requirements: food, packaging, or hygiene-sensitive areas may require barriers to reduce pest access, dust movement, and airflow between zones.
Temperature control needs: chilled rooms, freezer areas and temperature-sensitive workspaces may need closer overlap and a suitable PVC grade.
Internal vs external opening: external doorways are usually exposed to greater pest pressure, weather, draughts and vehicle movement.
Clear vs anti-insect PVC: clear PVC is often used where visibility is important, while anti-insect PVC is preferred where flying insects are a particular concern.
Strip width, thickness and overlap: these affect the amount of coverage the doorway provides, how easy it is to pass through, and how well the strips return to position after movement.
Made-to-measure vs standard kits: standard kits may suit common doorway sizes, while made-to-measure options are usually more appropriate for unusual openings, high-traffic areas or specific hygiene, access or temperature requirements.
Need help choosing a warehouse pest-control barrier?
The most suitable barrier depends on the doorway size, traffic type and how the area is used. A loading bay used by forklifts may require a different setup than a pedestrian entrance, a food production area, or internal storage space.
For a product or specification recommendation, send Strip Curtains Direct the doorway width and height, the type of traffic using the opening, and the main use case. For example, note whether the area is used for pedestrians, trolleys, forklifts, food handling, cold storage or general warehouse access.
FAQs
What is the best way to prevent pests in a warehouse?
The best approach is to combine physical prevention, good housekeeping, regular inspections and professional pest monitoring where needed. For busy warehouse doors and loading bays, physical barriers such as anti-insect PVC strip curtains can help reduce pest access while still allowing staff and goods to move through.
How do pests get into warehouses?
Pests commonly enter through open loading bays, gaps under roller shutters, damaged door seals, vents, drains, service penetrations, roof spaces, waste areas and incoming stock. In busy warehouses, open doors and goods-in areas are often the biggest everyday weak spots.
Do PVC strip curtains help with pest control?
Yes, PVC strip curtains can help reduce pest access by creating a flexible barrier across open doorways. Anti-insect PVC strip curtains are especially useful for areas where flies and airborne insects are a concern, such as food production, packaging zones, commercial kitchens and loading bays.
Are fly screens or PVC strip curtains better for warehouses?
Fly screens are useful for pedestrian doors, windows and ventilation points. PVC strip curtains are usually more practical for larger warehouse openings, loading bays and areas with frequent trolley, pallet or forklift movement.
