Pest control by species
Nine pest groups found in Saudi facilities, each with where it comes from, the sign that gives it away, the control that works and the record it leaves.
Each pest needs a different control. Rats need proofing and perimeter stations, German cockroaches need gel baits in their harbourage, drain cockroaches need wet traps and sealed drains, pharaoh ants must never be sprayed, and bed bugs need the whole block inspected. This page sets out nine groups found in Saudi facilities and how each is controlled.
Rats and mice
Rats and mice are controlled by proofing first: door sweeps, mesh on drains and vents, and sealed cable and pipe penetrations. Tamper-resistant bait stations then go on the external perimeter.
Norway rats burrow at ground level and live in sewers and drains. Roof rats climb, and in this region they nest in palm crowns, roof voids and false ceilings. House mice get through a gap about the width of a pencil.
The signs are droppings, greasy rub marks along walls, gnawing and burrows along the foundations. Inside food areas, most schemes expect non-toxic monitors and traps rather than toxic bait, except to treat an active infestation.

Two cockroaches, two different fixes
The German cockroach lives indoors and is controlled with gel bait placed in the cracks where it hides. The American cockroach lives in sewers and is controlled at the drain: covers fitted and floor drain traps kept wet.
The German cockroach lives in kitchens, warm equipment and motor housings, and arrives in deliveries and cardboard. Sticky monitors show where it is harbouring, and the gel goes into those cracks. General spraying scatters it through the building.
The American cockroach is large and comes up through drains at night. In summer heat an unused floor drain dries out and opens a path from the sewer, along with the smell. A wet trap and a fitted cover close it.

Stored-product insects in dry goods and dates
Stored-product insects live in the product, so control starts with the stock: rotation, clean spillage, an inspection gap between stock and walls, and pheromone traps in each zone to find the source.
Flour beetles, grain weevils and warehouse moths infest dry goods. Date stores get their own moths and saw-toothed grain beetles. The signs are webbing, holes in packaging, and larvae or adults at the light.
For exporters, khapra beetle is regulated as a quarantine pest in many importing countries, so a find becomes a commercial event, not just a hygiene one. Fumigation is managed specialist work, carried out by a licensed fumigator.

Flies, and why glue boards beat zappers
Flies are controlled at the source: waste removed often enough, bin stores and drains cleaned, doors screened. Insect light traps near food should catch on glue boards, because electric grids scatter insect fragments.
House flies breed in waste. Drain flies and fruit flies breed in drains and fermenting residues. Strip or air curtains go on the busy doors.
A light trap's UV tube loses output while it still glows, so tubes are replaced on a schedule, usually each year before summer, rather than when they look dim.

Birds at the loading bay
Birds are controlled by proofing: netting, spikes or wire on ledges, strip curtains, doors kept closed, and food and water sources removed. Nests come out as part of the proofing. The control is physical, not poison.
Feral pigeons, sparrows and mynas roost in warehouses, loading canopies and rooftop plant. Their droppings contaminate stock and corrode steel.

Termites under the slab
Subterranean termites are controlled by inspection, a soil treatment or baiting system around the building, and removing timber and cardboard that touch the ground. New buildings benefit from pre-construction treatment.
They come up from the soil in mud tubes and eat timber, cardboard and stored paper. The signs are mud tubes on walls and columns, timber that sounds hollow, and winged swarmers after rain.

Pharaoh ants: do not spray
Pharaoh ants are controlled with slow-acting bait, placed where they forage and left for them to carry back to the colony. Spraying makes colonies split and spread through the building.
They are tiny, pale and common in hospitals, kitchens and warm buildings. Other ants usually come in from outside and are handled at the entry point.

Scorpions and snakes on desert-edge sites
Scorpions and snakes are controlled through habitat: rubble, stacked materials and pallets cleared from near buildings, door sweeps and seals fitted, and gaps under containers closed. Snakes are removed by a trained handler, never by staff.
Compounds, labour camps, yards and plants on the edge of the desert see scorpions and occasional snakes, especially in the warm months. Lighting is placed so it does not draw insects, and their predators, to doorways. Night inspections use UV torches, under which scorpions glow.
A sting or a bite is a medical matter, and your site's first aid and emergency route apply.

Bed bugs in accommodation
Bed bugs need the whole block, not one room: neighbouring rooms are inspected, infested items stay where they are, bedding is laundered hot, mattresses are encased, and inspections repeat until the rooms are clear.
They travel in luggage, mattresses and furniture, and accommodation with rotating occupants is where they spread. The signs are bites, small dark spots on mattress seams, and cast skins.
Resident cooperation decides whether treatment works, so residents are briefed in their own languages.

A worked example: bites in three rooms
A labour accommodation block in Dammam reports bites in three rooms. The previous contractor sprayed those three rooms and left. Inspecting the whole floor, and the floors above and below, finds bed bugs in seven.
Four of the seven rooms had not been reported. Treatment covers all seven, neighbouring rooms are monitored, mattresses in affected rooms are encased and the laundry cycle for bedding is changed. The camp supervisor is asked to stop furniture moving between rooms, and residents are briefed with a one-page sheet in their languages. Follow-up inspections continue until two in a row find nothing.
The client holds a room-by-room inspection map, a treatment record with the operator's licence, the follow-up inspection log and a written note of the furniture rule, now in the camp's own procedure.
The record every problem leaves
Every species problem leaves five records: the inspection record with locations, the treatment record with the operator's licence, the action list with photographs, the follow-up log and an updated site or room map.
They are the same records the full programme keeps, so a one-off problem that becomes a contract starts with its history already on file.

- The proofing or habitat action list, with photographs

Questions from sites with a live problem
How fast can you respond to an active infestation?
At the priority your contract sets for pest incidents. Outside a contract, we arrange an inspection as soon as we can reach the site and tell you plainly when that is.
Will one treatment solve it?
Rarely. Most pests need proofing or a habitat change plus follow-up visits. One treatment without them is a recurring invoice.
Is the treatment safe around food and people?
Products are chosen for the location, applied by a licensed operator and recorded with the safety data sheet. Food areas use monitoring and non-toxic methods wherever possible.
Do you handle mosquitoes?
Around buildings, yes: standing water removed, and air conditioning condensate and drains checked. Public health vector programmes are run by the municipality.
Can we just buy a one-off treatment?
For audited facilities we recommend a programme. For a one-off, we still leave a record of what was found and what was done.
