Why they keep coming back in Harat Al Sarahin

Mosquitoes in Harat Al Sarahin move rapidly between neighbouring houses because the gaps are very tight and humidity is high year round. The method is set out in full on Mosquito control in detail.

The first reason

Mud built houses absorb water and humidity

Mud built and old houses absorb rain water and humidity from the sea air. Water remains in the house foundations for days.

The second reason

Tight gaps between houses trap water

The narrow spaces between closely spaced houses prevent air flow and water stays damp in them and dries only slowly.

The third reason

Low ground collects flood water

Harat Al Sarahin sits on low ground relative to the main road, so rain water and floods run to it and pool easily.

Before treatment

Standing water and shade decide the method

An old quarter in Thuwal with mud built and popular houses standing closely together, where old homes are being replaced. It is close to Thuwal Harbour and the coast.

The daytime biter

The daytime biter in Harat Al Sarahin rests in tight gaps and deep shade between closely spaced houses and in damp foundations.

The one that comes out after sunset

After sunset mosquitoes emerge from gaps and damp foundations searching for a host on low roofs and verandas.

Air-conditioning condensate

Air conditioning drains from the few units leave water in gaps and on floors, and the water does not dry because of high humidity and still air.

The tank and its openings

Water tanks on roofs may be a source if not covered or if their covers are loose. Water running from the street may enter them.

Potted plants in a garden standing in saucers

Garden containers and irrigation

Garden pots and irrigation are very few in the old quarter but water pools in any gap between houses and in damp floors.

The shade it rests in

Deep shade, permanent humidity in gaps, foundations and floors make them an ideal resting place for adult mosquitoes 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.

The character of Harat Al Sarahin

Mixed district: shops at street level with homes above them

Ground floor shops if present may be a separate source, but the core problem lies in the houses themselves: walls and foundations absorb water and gaps between them trap it.

Questions about this district

Do mud built houses hold water much longer than modern ones?

Yes, much longer. Mud is absorbent and soaks up moisture and water for a long time. Mosquitoes find a permanently damp habitat in mud houses.

Are the tight gaps between houses a major mosquito source?

Yes. Tight gaps trap air and water. Mosquitoes hide there by day and emerge after sunset. Treatment must reach these gaps.

Is treating my house alone enough or does the whole quarter need treatment?

Mosquitoes in the quarter move easily between closely spaced houses. Treating one house may not work. District wide treatment is far better.

Does the humidity from the harbour and coast make mosquitoes much worse?

Yes, much worse. High sea humidity prevents water drying and lengthens the breeding cycle. Mosquitoes in a quarter this close to the harbour are far more numerous.

Do I need weekly treatment or will monthly visits work given all this humidity?

In Harat Al Sarahin with high humidity and tight gaps you need treatment at least every two weeks, especially in humid seasons.

Does treating the gaps between houses stop mosquitoes moving from one to another?

Gap treatment is very important because they are the paths mosquitoes use to move between houses. But you must treat the inside of the house too.

How much does mosquito control in Harat Al Sarahin 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 Sarahin.
