Mosquito control in Harat Al Sawalhah Jeddah

Harat Al Sawalhah is a traditional quarter of Thuwal close to the corniche and harbour, with older houses on very narrow streets that have received modern paving and lighting under the Thuwal development programme. Shops occupy the ground floors with homes above, and mosquitoes are drawn from the sea and harbour and the corniche, breeding in salt water pooling around old foundations and dark narrow passages.

Why they keep coming back in Harat Al Sawalhah

Narrow streets block the sun all day and humidity from the corniche and harbour accumulates in passages and dark corners. The method is set out in full on our Mosquito control service.

The first reason

Closeness to corniche, harbour and salt water

Harat Al Sawalhah is very close to the corniche and harbour, and high humidity and salt in the air provide ideal conditions for sea mosquitoes. Salt water pooling around old foundations creates particular breeding conditions.

The second reason

Narrow streets and permanent shade

Streets are very narrow and old buildings block the sun completely. This creates damp permanent shadows in passages where mosquitoes rest during the day without fear of drying out or direct sun.

The third reason

Shops, restaurants and shared sanitation

Ground floor shops leave water from kitchens and shared sanitation. Water has no good drainage in the old quarter, so it pools in corners and passages between shops and buildings.

The character of Harat Al Sawalhah

Mixed district: shops at street level with homes above them

A mixed district with shops at street level and homes above near the sea means mosquitoes drawn from the sea, harbour and corniche with high humidity. Effective treatment needs understanding of sea mosquito types and high salt humidity, not standard treatment alone.

Before treatment

Standing water and shade decide the method

A traditional quarter with very narrow streets and old buildings close to the corniche and harbour, with shops at street level and residential space above.

The daytime biter

Daytime mosquitoes in Sawalhah shelter in the permanent shade of narrow streets and passages between buildings and shops.

Drainage from ground floor shops from kitchens and sanitation flows through very narrow passages with no orderly system.

The tank and its openings

Water containers and shared sanitation in the quarter provide breeding sites in permanent shade and high humidity.

The shade it rests in

Permanent shade and humidity from the corniche and harbour provide ideal conditions for sea mosquitoes throughout 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.

Landmarks of Harat Al Sawalhah

Harat Al Sawalhah lies between Thuwal Corniche and the old harbour, where the sea and high humidity and shops on the Jeddah Madinah Road provide access routes and define how the quarter is treated. Thuwal Cultural Centre and the harbour mark the geographical position of the quarter and the maritime environment that provides continuous mosquito sources.

Questions about this district

Does salt from the corniche affect the type of mosquitoes in Sawalhah?

Yes, mosquitoes in Harat Al Sawalhah are adapted to salt and high humidity from the sea. This makes them different from inland districts.

Is the old quarter with poor drainage a continuous mosquito source?

Yes, the old quarter has very slow drainage, and water pools in corners and passages for days, providing permanent breeding conditions.

Is treating very narrow streets very difficult?

Narrow streets need precisely directed treatment, because spray may not reach far corners. We use different methods for enclosed and narrow passages.

How often does Harat Al Sawalhah need treatment?

At least twice monthly in the warm season, because high humidity and pooling water create fast breeding conditions.

Are ground floor shops and restaurants the main problem?

Yes, shops and restaurants provide continuous water from kitchens and sanitation, and it pools in dark passages and corners.

Did the development programme add to or reduce mosquito problems?

The programme improved lighting and paving, but drainage improvement is limited. The problem remains in passages and corners.

How much does mosquito control in Harat Al Sawalhah 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 Sawalhah.
