Preventive treatment in Petromin Jeddah

Petromin is a low-income quarter in south Jeddah that takes its name from and sits directly beside the Jeddah oil refinery, separated by one main road. It was included in the city's slum clearance and replanning scheme, but the houses are still new and incomes are low and housekeeping is limited. The preventive programme here must handle daily pressure from the refinery, waste disposal nearby and tight gaps between tight buildings.

Why they keep coming back in Petromin

Insect pressure here is much higher than in other Jeddah districts and may include species linked to refineries and industrial waste. The method is set out in full on Preventive treatment in detail.

The first reason

The refinery right beside and gaps in the fence

The refinery is directly adjacent and the fence may have gaps or cracks. Insects and rodents travel from refinery into the neighbourhood.

The second reason

Industrial waste and debris nearby

Refinery waste and industrial processes provide food and shelter for insects. Houses close to the fence feel this pressure more than others in the district.

The third reason

Low income and limited housekeeping

Residents have limited income and housekeeping is constrained by economic factors. Open drains and rubbish around houses create ideal insect habitat.

Before treatment

What a preventive visit reads

The refinery sits beside the district and releases odours and fumes. Waste and debris from the refinery may reach the neighbourhood. Some houses still sit very close to the refinery fence and the fence may have gaps.

The base of an exterior wall where the building meets the ground

The base of the outside wall

The outer wall base and the boundary wall facing the refinery fence must carry very strong protection.

An exterior door threshold and the gap beneath it

Gaps and openings

Gaps and cracks between the neighbourhood and the refinery fence must be sealed or monitored continuously.

An outdoor air conditioning unit with a condensate pipe on the wall

Air conditioning condensate

Cooler condensate may drain onto dirty ground near the fence or may attract insects coming from the refinery.

Floor drains

Floor drains may be open or unsealed, allowing insects to climb from the shared boundary.

A drip irrigation line in damp soil beside planting

Irrigation against the wall

Irrigation against walls is light but industrial waste and refinery debris may provide enough moisture and food.

A closed monitoring station at the foot of a wall

The monitoring points

Monitoring points must concentrate on the fence, gaps facing the refinery, and all openings at the boundary.

How we work

1
The baseline survey

We walk the outside boundary and then the inside: gaps under doors, pipe runs, vents, condensate lines, drains, the bin area and the store, and we fix the monitoring points before anything is applied.
2
Close the routes

Mesh on the vents, the gap under the door dealt with, the sleeve around a pipe run closed, and water put back into the drain nobody uses. Exclusion saves a spray that would otherwise repeat forever.
3
The band and the placed product

A residual band at the base of the wall outside and around door and window openings, with placed product inside joints and closed voids where it is warranted, and no open spray across living surfaces.
4
The scheduled visit: read, renew, record

We read the points to see which side is under pressure, renew the band where sun or irrigation has taken it, aim the visit at what the coming season opens up, and write down what was found and what was used.

What the preventive programme includes

A survey, then a check every visit

Entry points, moisture sources and storage, recorded before anything is applied and revisited each time.
Monitoring points that get read

At the wall and floor junction, under sinks and in the store, checked on every visit rather than only the last one.
A renewed exterior band

At the wall base and around the openings, put back wherever sun or irrigation took it between visits.
Drains, water lines and waste

The water seal in the drains, the condensate line and the ground around the bins, which are the standing water and food sources.
Between the visits

What to keep dry, what to keep closed, and what is worth a call before the next date. Ventilation we tell you before the visit.
A scheduled visit and a record of each

An agreed date, what the points held, what was treated, and what changed since last time.

Landmarks of Petromin

Petromin sits on Al Falah Road near the Al Nujoom Roundabout, which means visit schedules follow the main road grid. The refinery fence and the dividing street are the landmarks that divide the neighbourhood into monitored zones.

Questions about this district

Is the refinery immediately beside the neighbourhood a direct insect pressure source?

Yes, strongly. Houses beside the refinery fence may feel much higher pressure than others in the district. The pressure is direct and constant.

Can gaps in the fence between the neighbourhood and the refinery let insects and rodents through?

Yes. Any opening or crack in the fence allows insects and rodents from the refinery to cross. These are critical points.

Does industrial waste from the refinery attract particular insect species?

Yes. Industrial waste may attract insect species different from normal household insects. The programme may need specialised approaches.

How often does the technician visit a house in Petromin each month?

Visits may be weekly or every ten days because refinery pressure is continuous. Prevention never stops here.

Does limited housekeeping increase the need for a stronger preventive programme?

Yes. Limited housekeeping and waste disposal mean higher pressure. The programme must be stronger and more frequent.

Has the new building and improved housing reduced pressure compared to the old informal settlements?

New building helped but refinery pressure has not changed. New houses may be easier to protect than old ones but the external pressure is the same.

How much does preventive treatment in Petromin cost?

It is set after the inspection, because the price follows the type of infestation, the size of the space, how far it has spread and the number of visits it needs. Send a photo and a description on WhatsApp and we will give you an estimate before we reach Petromin.
