Why they keep coming back in Harat Al Baharah

Flies in Thuwal are present throughout the year, and high sea humidity means they do not die back or rest even during colder months like they would in dry districts. The method is set out in full on Fly control in detail.

The first reason

Continuous sea humidity year round

Salt laden humid sea air keeps insects active throughout the year. Flies that would die in dry areas stay alive and breeding in high moisture even in winter.

The second reason

Ancient drainage beneath tightly built houses

Old public sewage runs under old houses packed closely together. Failing or leaking drains mean soil stays damp and full of flies deep underground where ordinary spray cannot reach.

The third reason

The fishing port and constant seasonal activity

Thuwal Harbour is active year round with fish and waste on the quay providing endless fly nutrition. Flies move from the port to the quarter within hours on warm coastal air.

Landmarks of Harat Al Baharah

Harat Al Baharah sits wedged between Thuwal Harbour on one side and the Thuwal Corniche that Saudi Aramco maintains on the other, so treatment focuses on the quarter itself and the narrow passages between it and the harbour where flies move easily.

Before treatment

Where the flies are actually coming from

The quarter sits directly on the coast near Thuwal Harbour and its corniche, with old mud and concrete buildings packed closely on streets so narrow that air barely moves between them.

House fly

The house fly in an old seaside quarter breeds faster because moisture and warmth continue all year in sea air.

Blow fly

The blow fly is extremely common in Harat Al Baharah because it is drawn to fish and organic waste on the quay and corniche.

Fermenting residue

Fermenting residue from fish offal and organic waste at the harbour and in the quarter is the primary source, not just household bins.

The bin base

The bin base in the old quarter sits exposed to salt and spray, and flies breed around the bin even if it is clean.

The film inside a drain

The film inside old drains beneath the buildings is certain to exist, with moisture salt and waste flowing through from the harbour constantly.

The service door and its mesh

The service door and its mesh in a seafront house must be heavy and hole free because warm sea air carries flies directly from the corniche.

How we work

1
Inspect and trace the source

We trace the flies back to their medium: waste and the bin area, floor traps, drain runs and any standing organic wetness, and we identify the species from its size, its flight and where it settles.
2
Treat the breeding medium

Washing and scouring bin bases and floor traps, and a foam that treats the film inside the pipe, because removing the medium is the only thing that stops production.
3
Treat the resting surfaces

A fly spends most of its time settled on ceilings, cables, the tops of walls and the sunlit wall outside the door, and that is where the residual and the bait go, not into the air.
4
Proofing and the follow-up

We close the ways in and sort out the screens and the doors, then come back on a date matching the emergence of the pupae that were already in the medium on the first visit.

What fly control includes

A source tracing inspection

The species, the breeding medium and the route in, established before anything is applied.
Drains and floor traps

Scouring the film stuck inside the pipe and treating it with foam, which is where drain flies come from and almost nowhere else.
Residual on the resting surfaces

Ceilings, cables, the tops of walls and the sunlit wall outside the door, kept off food preparation surfaces.
Fly bait in protected positions

An attractant bait set at bin areas and service entrances, out of reach of children and pets and away from food.
Aftercare instructions

Ventilation, what to cover, and what needs a screen, an air curtain or a different waste routine.
A scheduled follow-up

A set date matching the emergence of the pupae, and re-treatment of any source still producing.

What is different about Thuwal Sub-Municipality

Thuwal sub municipality is a small fishing town on the Red Sea coast at the far northern edge of Jeddah governorate. Its old quarters are closely packed popular and mud built houses on narrow streets, with newer low rise concrete homes from the town's development programme beside them. Sea humidity stays high all year, the fishing harbour and the corniche form its seafront, water arrives by tanker so household tanks are everywhere, and the town sits on Wadi Thuwal, ringed by open ground and by the irrigated green campus of King Abdullah University of Science and Technology.

Questions about this district

Why are there more flies in an old seafront quarter than anywhere else?

High sea humidity speeds larval development, ancient drainage provides constant moisture beneath buildings, and the fishing port beside you provides endless nutrition.

Does salt in the sea air affect how fly treatments work?

Yes, moisture and salt protect flies from rapid drying after treatment. Treatment needs more frequent repeating in coastal areas.

Does treating Thuwal Harbour and corniche reduce flies in the quarter?

Harbour treatment is important but not your responsibility. We focus on treating the quarter itself and the sewage running beneath the buildings. Flies from the port will naturally reduce over time.

How many treatments per year does an old seaside quarter need?

In damp coastal areas, treatment every six weeks or so is recommended. Continuous moisture means rapid breeding cycles throughout the year.

Does old mud and stone in buildings hold more moisture than modern concrete?

Yes, porous stone and mud absorb and hold moisture longer, meaning permanent damp conditions remain beneath the house.

Do flies come from the university campus or only from the harbour?

The harbour is the main source, but irrigated landscaping on the university grounds may provide additional flies. Treating the quarter itself is most important.

How much does fly control in Harat Al Baharah 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 Harat Al Baharah.
