Why they keep coming back in Harat Al Mazloum

The narrow lanes do not dry after rain for days. Water collects beneath the ground between ancient stones where nobody sees it, held by the old buildings that act as a capillary pump drawing moisture up from below. The method is set out in full on the full Mosquito control page.

The first reason

Coral stone and ancient timber structures

Coral stone absorbs humidity from the sea and harbour. Wooden rawashin window screens and undersurface timber stay damp all year. Mosquitoes do not lay eggs only in flowing water. They lay them in damp crevices in wood and stone, where water is trapped but invisible. The old house is a natural humidity store.

The second reason

Narrow lanes and permanent shade

Lanes between houses are so tight that the sun never reaches the ground. Water from rain and washing flows through them and never dries. The air is humid and sea fog enters after dark. The shade persists all day and deepens at night.

The third reason

Trading souqs and eateries within the quarter

Souq Al Jami and Souq Al Badu operate daily. Cramped restaurants and cafés wash their floors several times a day. Water runs down into the ancient foundations and hides underground, feeding the ecosystem of wood, stone and air voids where mosquitoes breed unseen.

Landmarks of Harat Al Mazloum

Around Souq Al Jami and Bab Makkah the quarter gathers with its markets and houses. Treatment begins from Al Alawi Street and reaches into every house and lane, including the underground surfaces and the stone crevices that cannot dry by themselves and have held moisture for centuries.

Before treatment

Standing water and shade decide the method

The ground lies low and very close to the sea and harbour. Humidity remains high throughout the year. Ancient commercial souqs like Souq Al Jami trade from dawn to late evening, and cramped eateries wash their floors almost hourly, feeding water to the underground voids beneath.

The daytime biter

The daytime biter in Harat Al Mazloum never leaves the narrow lane, sheltering in the permanent shade between the stone houses, approaching only the doorstep as dusk nears.

The one that comes out after sunset

The one that comes out after sunset rises from the underground voids and low surfaces, flying between the tightly packed houses in search of entry before dawn.

Rain water and restaurant water and constant washing all fall into the lanes and do not dry because of the shade and the low stone surfaces that hold it underground.

The tank and its openings

Old tanks in the houses and souqs are rarely opened or cleaned, and eggs wait inside them until the next season brings new water.

Garden containers and irrigation

There are no gardens in Harat Al Mazloum, but restaurants water narrow pots on the lane steps, and the water soaks into the stone.

The shade it rests in

The shade underground and between the houses stays damp and dark all year even in summer, where the adult mosquito rests out of every sight.

How we work

1
Inspect and map the water

We walk the perimeter, the roof, the garden, the meter chambers and the condensate runs, record everything that holds water, and read the species from the breeding site and the time of biting.
2
Remove the water that can go

Empty, invert, cover: saucers, containers, old tyres and roof gullies. Every point that disappears is a treatment that never needs repeating.
3
Larval treatment, then the resting surfaces

Water that cannot be drained is treated so the larva never completes, then a residual goes under planting, beneath outdoor furniture and along low shaded walls.
4
The follow-up visit

We come back once the generation that was in the water on the first visit has completed, review every point we recorded and re-treat where needed.

What mosquito control includes

A recorded water survey

Roof, perimeter, garden, meter chambers and condensate lines, written down before anything is applied.
Draining and covering the sources

Emptying what can be emptied, draining what can be drained, and covering what has to stay full.
Larval treatment for the water that stays

For ground tanks, inspection chambers, water features and any permanent water that has to remain.
A residual on the resting places

Under trees and shrubs, beneath outdoor furniture and on shaded walls, where the adult sits out the day.
Aftercare instructions

What stays inverted, what gets covered, which openings need mesh, and when watering goes back to normal.
A scheduled follow-up

A set date after the first treatment, with every recorded water point reviewed and re-treated if the water came back.

What is different about Historic Jeddah Municipality

The Historic Jeddah municipality covers the quarters of Al Balad inside the old wall: Al Mazloum, Al Sham, Al Yaman and Al Bahr. The buildings are tall houses of coral limestone and timber rawashin, centuries old, standing shoulder to shoulder on narrow lanes that see little sun, many under restoration or partly vacant. The ground is low and close to the sea and the harbour, humidity stays high through the year, and popular souqs and eateries trade late into the night. Old timber, voids between walls and goods stores create conditions favoured by termites, cockroaches, rodents and wood boring beetles.

Questions about this district

The house is very old and always damp. Why are there so many mosquitoes?

Coral stone absorbs humidity from the sea and never dries out completely. The wooden rawashin screens and undersurface timber have tiny crevices everywhere. Mosquitoes lay eggs in water and in damp cracks. An old house is a natural humidity reservoir.

The lane is very narrow and the sun never reaches it. Is that why we have mosquitoes?

Yes. Mosquitoes are drawn to shade and dampness. A lane where the sun never reaches is damp and dark all day and all night. This is perfect habitat. The mosquito spends most of its day there.

The restaurant below the house in the lane washes its floor every hour. Does that breed them?

Yes. Warm water from the restaurant wash runs down into the old foundation. Mosquitoes lay eggs in that water. Treatment must include both the restaurant and the house above it.

The foundation below is like a wet dark cave. Can it be treated?

Yes, if it has access openings. Old foundations hold water and dampness and are perfect breeding conditions. Treatment from inside is best, and if we cannot reach inside, we apply treatment from above downwards.

Does the high humidity after rain increase mosquitoes here especially badly?

Yes, very much so. The narrow lanes do not dry for days after rain. Water collects underground between stones and foundations. Mosquitoes lay millions of eggs during these days.

Do you treat the gaps between old houses and the underground surfaces?

Yes. Gaps between stones and damp timber are the main source in the old quarter. We enter through every door and opening, and apply treatment downwards from above into the voids.

How much does mosquito control in Harat Al Mazloum 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 Mazloum.
