Why they keep coming back in Harat Al Amir

The air is salt laden and humidity stays high year round in Thuwal, water comes by tanker so household tanks are everywhere. The hard humidity speeds egg development and mosquito growth faster than inland neighbourhoods away from the sea. The method is set out in full on how we approach Mosquito control.

The first reason

Tanks are many and water arrives by tanker

Thuwal depends on water tankers, so every house has one or more large household tanks. The tank opens daily at refill and the opening gives mosquitoes entry to lay eggs in the water, unlike neighbourhoods on the public network.

The second reason

Sea humidity speeds mosquito life cycle

High humidity year round in Thuwal accelerates egg and larval growth, so the cycle from egg to adult falls below a week when humidity is high. More mosquitoes breed faster as a result.

The third reason

Narrow streets and packed homes spread the problem

Vernacular houses stand very close together and streets are narrow, so a mosquito flying from a neighbour's tank reaches your home readily. Building density means rapid spread and treatment needs wider coverage.

Landmarks of Harat Al Amir

Work in Harat Al Amir is organised through its narrow streets. Approaching from the Jeddah Madinah Road, Thuwal Municipality Building comes first, then you drop toward the corniche and Al Shati Mosque where the quarter lies. Each home needs its tank inspected and its old pipe drainage checked at the side.

Before treatment

Standing water and shade decide the method

Harat Al Amir sits in small Thuwal on the Red Sea coast at the far northern edge of Jeddah, close to the municipality building, the mosque, schools, the corniche and the fishing harbour.

The daytime biter

The daytime biter in Harat Al Amir hides in the shade of narrow streets and tightly packed homes and behind doors and windows. The narrow street provides shade nearly all day.

The one that comes out after sunset

After sunset the mosquito leaves cover to hunt, and Thuwal's narrow streets are dimly lit, so the mosquito finds its way easily from a tank to your home where people sleep.

Air-conditioning condensate

Air-conditioning condensate and water leaks from old pipes in narrow streets pool and create standing water in corners and low points.

The tank and its openings

Water tanks in Thuwal fill by tanker and sometimes sit half empty, and the large top opening offers easy mosquito entry and collects rain.

Garden containers and irrigation

Pots, drums and water from old irrigation leaks in vernacular homes supply standing water that goes uncleaned.

The shade it rests in

Shade in Harat Al Amir is permanent from narrow streets, tightly spaced homes and clustered buildings, so adult mosquitoes find cover day and night.

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 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

Is a tank filled by tanker a certain mosquito source?

Yes, every tank opens at refill, and the opening gives mosquitoes entry to lay eggs in the water. Eggs grow fast in warm standing water, especially in a warm, humid coastal town like Thuwal.

Why is the mosquito problem worse in Thuwal than in the city?

Sea humidity and warmth year round speed mosquito growth, and tanker water means tanks hold water longer and more openly. Houses stand close, so mosquitoes travel easily from one to the next.

Is the corniche and harbour beside the homes a mosquito source too?

The corniche and harbour hold salt water and waste, which does not attract freshwater mosquitoes. But standing water in quiet areas behind the harbour may be an additional source for coastal mosquitoes.

Does protecting the tank opening solve the mosquito problem?

Protecting the tank opening with fine mesh or a tight cover prevents mosquito entry significantly. But this protects your tank only; mosquitoes from neighbours' tanks will still reach your home.

Is fogging alone enough in a damp coastal place like Thuwal?

Fogging alone is not enough in humid coastal conditions, because mosquitoes breed fast and humidity shields the eggs. Treatment includes draining standing water, fogging shaded surfaces and treating the water itself.

When should mosquitoes drop in the small town after the first visit?

Mosquitoes drop quickly from treated water, but eggs in neighbours' tanks keep growing. A second visit after a week is needed to target eggs that have hatched from nearby tanks.

How much does mosquito control in Harat Al Amir 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 Amir.
