Mosquito control in Al Harah Al Janubiyah Jeddah

Al Harah Al Janubiyah is the southern part of Thuwal town, popular housing on tight streets with open edges facing farms and empty ground. The Jeddah Madinah coastal road runs below it and the sea lies to the east, and rain water runs from the upper edges towards the sea with no regular drainage system. Mosquitoes thrive here because coastal humidity and standing water in the gaps between old homes create ideal conditions.

Why they keep coming back in Al Harah Al Janubiyah

In coastal towns with old housing, high humidity and standing water in gaps give mosquitoes ideal conditions year round. The method is set out in full on the full Mosquito control page.

The first reason

Narrow streets and trapped water

Streets in the southern quarter are very tight and rain water creeps slowly through them. Gaps between old homes trap water and keep it damp.

The second reason

Open edges and farms

The quarter adjoins farms and empty land, and rain water comes from the farms and higher ground. These open areas provide many sources of standing water.

The third reason

Coastal humidity and salt air

The coastal location near the sea keeps humidity high through the year. Soil and homes stay damp even without obvious standing water.

Before treatment

Standing water and shade decide the method

Popular old houses on narrow streets with open edges facing farms, and the coastal location keeps humidity high.

The daytime biter

The daytime mosquito hides in the narrow gaps between old houses and the permanent shade in tight streets.

The one that comes out after sunset

After sunset it flies from the gaps and streets to find a host in nearby homes and courtyards.

Rain water from the farms creeps slowly through the tight streets and pools round the homes.

The tank and its openings

Water tanks may exist in some homes but coastal humidity is the core problem.

Garden containers and irrigation

Garden containers and irrigation water may be found on the home edges or in the neighbouring open ground.

The shade it rests in

Permanent shade in the tight streets and high humidity offer complete mosquito shelter.

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.

Questions about this district

Why are mosquitoes so heavy in the southern quarter?

Coastal humidity is high year round, narrow streets trap rain water, and open ground round the quarter provides standing water sources.

Do the farms next door feed mosquito breeding?

Exactly. Irrigated farms are very close, and water from irrigation and rain drains straight towards the quarter.

Does salt air from the sea kill mosquitoes?

Salt air does not kill them, but high humidity offers perfect conditions. Coastal mosquitoes are adapted to salt and dampness.

Do old tight streets increase mosquito numbers?

Very much so. Tight streets dry slowly after rain and water stays seeping through the gaps.

Is treating the quarter alone enough or do the farms need treatment too?

Treating the quarter helps but the farms and open ground keep feeding new water. Ongoing treatment and monitoring are essential.

When are mosquitoes at their worst in the southern quarter?

Spring and summer when humidity rises and irrigation season starts. Year round high humidity keeps mosquitoes a permanent problem.

How much does mosquito control in Al Harah Al Janubiyah 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 Harah Al Janubiyah.
