Fly control in Harat Al Bahr Jeddah

Harat Al Bahr occupies the south western corner of historic Jeddah's waterfront, with old coral stone houses standing directly on or above the harbour's edge. The streets are extremely narrow, the drainage system is ancient, and the ground sits low where seawater and moisture penetrate constantly. This combination of age, dampness and proximity to the sea creates fly conditions unlike any other district in Jeddah.

Why they keep coming back in Harat Al Bahr

The old stone houses here remain perpetually damp from the sea and the water table, and flies breed continuously in this moist environment without seasonal interruption. The method is set out in full on Fly control in detail.

The first reason

Permanent dampness in ancient masonry

The old coral stone buildings sit at the harbour's edge where seawater and groundwater penetrate constantly. This perpetual dampness creates ideal breeding conditions for flies throughout the year, and no amount of cleaning the surface will stop them breeding inside the damp walls and foundations.

The second reason

Ancient shared drainage is inaccessible

The narrow lanes and close-packed houses share extremely old piping that runs beneath the streets. Fly larvae live in these drains, and they cannot be killed by surface treatment alone. The drains run between buildings, making isolation or individual treatment ineffective.

The third reason

The harbour is a continuous fly source

The nearby harbour and anchorages provide constant food sources for flies: fish scraps, marine waste and salted goods stored in old warehouses. Flies breed abundantly there and spread immediately into the surrounding houses.

The character of Harat Al Bahr

Historic district: close-set buildings, narrow lanes and ageing services

Harat Al Bahr is historic and ancient in construction, and the fly problem here is not a cleanliness issue alone but a permanent damp environment. Treatment requires a different strategy for old buildings and shared pipes that cannot be separated or isolated from each other.

Before treatment

Where the flies are actually coming from

The district lies on low ground at the waterfront's edge, meaning high humidity, seepage into foundations and perpetually damp walls throughout every building.

House fly

House flies in Harat Al Bahr feed on food scraps, dried fish and marine waste that accumulate in the narrow lanes and homes so close to the harbour's edge.

Blow fly

Blow flies appear in high numbers around houses near the harbour and in old storage rooms, particularly during warm periods when maritime traffic peaks.

Fermenting residue

Fish remains and marine waste collect in the narrow lanes and blind passages behind house rows, forming ideal fermenting substrate where flies breed continuously.

The bin base

Bin bases and containers in the narrow streets collect liquid run off from fish and salt goods stored in nearby warehouses, creating pools of organic matter.

The film inside a drain

Drain films coat the shared ancient piping that connects all houses in the quarter, providing perfect larval habitat sustained by perpetual dampness.

Old wooden doors and shutters fit poorly and most window mesh is broken or missing, allowing direct entry of flies from the harbour and streets into every house.

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.

Landmarks of Harat Al Bahr

Work in Harat Al Bahr is organised along Qabil Street, the commercial lane that runs through the quarter. The old stone houses clustered around Bab Al Bunt at the waterfront's edge demand special treatment for the moisture and shared drainage they retain.

Questions about this district

Why are there far more flies here than in newer districts of Jeddah?

Permanent dampness, proximity to the harbour and ancient construction create unique conditions. Flies find food, water and shelter everywhere, and the drains breed them year round without seasonal breaks.

Do the flies come directly from the harbour or from waste in our homes?

Both. The harbour is a major source where fish scraps and marine waste sustain flies in large numbers, but the waste in homes and narrow streets also provides perfect breeding ground.

Are the old pipes beneath the streets full of fly larvae?

Yes. The shared ancient drainage that runs under Harat Al Bahr maintains permanent dampness and is an ideal breeding environment for fly larvae at all times.

Does the moisture in foundations and walls increase flies?

Dramatically yes. Perpetual dampness creates ideal fermenting conditions for organic matter, vastly increasing fly breeding and the numbers you see.

Is treating a single house enough or must the whole alley be treated?

Houses here are too closely linked through shared drains and walls. Treating one house alone will fail. The flies will return from the breeding in neighbouring houses and shared pipes.

Is fly treatment harder in Harat Al Bahr than in modern districts?

Yes, considerably. The ancient structures, complex shared drainage and permanent dampness make it much harder to reach every breeding site and maintain control over time.

How much does fly control in Harat Al Bahr 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 Bahr.
