Mosquito control in Al Hajlah Makkah

Al Hajlah is an extremely narrow quarter along Ibrahim Al Khalil Street south west of the Grand Mosque, squeezed between two hills. The old firewood market became a wall of pilgrim hotels and rental apartment blocks climbing toward the mosque courtyards. Hotels use continuous water supply. Gaps between buildings are tight and humidity is trapped. The street slopes upward toward the mosque, meaning water does not drain away but pools in narrow crevices. This is a completely unique environment.

Why they keep coming back in Al Hajlah

In Al Hajlah buildings are so densely packed and windows open onto the same narrow street that humidity from hotels and rental blocks reinforces itself and accumulates continuously. The method is set out in full on how we approach Mosquito control.

The first reason

Narrow crowded hotels are continuous water sources

Hotels in Al Hajlah are extremely tight spaces using water constantly for guests and cleaning. Water spills into cavities so narrow between buildings that it cannot evaporate. Each hotel is an independent mosquito source but they stand so close together that they act as one.

The second reason

The upslope street prevents water from draining away

The street rises toward the mosque, so water flows downhill but pools in tight gaps along the way. Water does not drain away but remains stagnant. Larvae complete development in these pockets.

The third reason

Gaps between buildings are impossibly narrow and trap humidity

Service gaps in Al Hajlah are so tight that a person cannot pass sideways through them. Air does not circulate and humidity is completely trapped. Mosquitoes live extended lives in these airless spaces.

Before treatment

Standing water and shade decide the method

Al Hajlah sits on Ibrahim Al Khalil Street between two hills immediately adjacent. The street is extremely narrow and tall buildings block air circulation. Every drop of water that falls or spills remains in the tight gaps.

The daytime biter

Daytime mosquitoes in Al Hajlah shelter in the impossibly narrow gaps between hotels and rental blocks, where shade from surrounding mountains and tall buildings is permanent.

The one that comes out after sunset

After sunset colonies emerge from hotel systems and narrow cavities in large numbers, and the tight street traps air movement, creating intense flight activity.

Air-conditioning condensate

Hotel air conditioning leaks warm water into cavities so tight that evaporation cannot occur, and water persists in darkness with high humidity.

The tank and its openings

Water tanks in hotels and rental flats are supplied by aged systems that may leak contamination from underground cavities. Warm water persists and breeds heavily.

Garden containers and irrigation

Small fountains and potted plants in hotel lobbies hold fresh water daily, and overflow spills into gaps between floors and buildings.

The shade it rests in

Permanent shade from Jabal Omar and surrounding mountains and tall buildings creates perfect refuge for daytime resting adults throughout the year.

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.

Landmarks of Al Hajlah

In Al Hajlah treatment focuses on the impossibly tight gaps between densely packed hotels and rental blocks on Ibrahim Al Khalil Street, with special attention to the Grand Mosque nearby and the buildings climbing toward the expansion courtyards. Hotels, gaps and standing water are all interconnected parts of one system.

Questions about this district

Are Al Hajlah hotels harder to treat than hotels elsewhere in Makkah?

Substantially harder. Hotels here are extremely tight and gaps between them are impossibly narrow. Water does not evaporate and humidity stays trapped. Each hotel is a concentrated breeding site.

Does the upslope street help or hinder mosquito control?

Hinders it severely. The upslope forces water to pool in tight gaps instead of flowing away. Standing water persists longer and produces more adults.

Does Jabal Omar beside Al Hajlah affect the mosquito problem?

Yes significantly. The mountain blocks air and sunlight from the quarter. Shade and trapped humidity mean mosquitoes live longer.

Does treating one hotel affect the neighbouring hotel?

Yes completely. Hotels stand so close that gaps between them are service spaces only. Treatment of one hotel requires simultaneous treatment of neighbours.

Do rental apartments have the same mosquito burden as hotels?

Yes and worse. Rental blocks are old and drainage is extremely aged. Every flat holds standing water in different locations.

Is Al Hajlah difficult to access for treatment?

Extremely difficult. The street is narrow and buildings stand so close together. Reaching hotel interiors and gaps between buildings is very challenging.

How much does mosquito control in Al Hajlah 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 Al Hajlah.
