Mosquito control in Wadi Jaleel Makkah

Wadi Jaleel is a valley district north east of Makkah nestled between hills, a tributary of Wadi Liyyah and a strong flash flood channel, with new housing schemes spreading along Al Hajj Street and the fourth ring road. Heavy rain sweeps the valley but leaves ground waterlogged for days. Modern building has not solved the problem; standing water around new villas remains a constant mosquito source.

Why they keep coming back in Wadi Jaleel

Ground stays waterlogged for days after floods; modern drainage systems cannot handle the volume of water from heavy downpours, leaving water pooling in unexpected low spots. The method is set out in full on the full Mosquito control page.

The first reason

Strong floods and water pooling after rain

Wadi Jaleel is a tributary of Wadi Liyyah and a strong flood channel; heavy rain sweeps the valley quickly but leaves the ground very wet. Water pools in low areas around villas and the planned district, often staying for several days without drying.

The second reason

Modern building and inadequate drainage

The district is new and houses are modern but drainage systems were not designed for flood volumes. Low ground around new villas collects heavy water that may take days to dry.

The third reason

Low ground and tight gaps between villas

New villas are close together and gaps between them are tight; rainwater and drainage run downhill from the main street into these gaps. These tight spaces may hold high moisture and become mosquito habitat.

Wadi Jaleel sits about 3 km from Qurtubah and about 3.5 km from Jabal Al Noor.

Before treatment

Standing water and shade decide the method

A valley district among the hills north east of the city, a tributary of Wadi Liyyah that carries strong flash floods after heavy rain. New housing schemes along Al Hajj Street and the fourth ring road spread over its floor, within sight of Jabal Al Nour and the Hira cave.

The daytime biter

The daytime-active mosquito in Wadi Jaleel shelters in gaps between villas and low-lying damp areas and wet corners around homes.

The one that comes out after sunset

After sunset mosquitoes emerge from gaps and low zones; high moisture from floods makes night hours very active.

Water sources are many after floods: gaps between villas, low ground areas and drainage from the main street.

The tank and its openings

Rooftop tanks on modern villas are mostly well-sealed, but water leaks may occur at pipe connections.

Garden containers and irrigation

Small gardens in some villas provide multiple water sources: irrigation systems, potted plants and small pools.

The shade it rests in

Permanent shade under villas and tight gaps between them provide comfortable shelter where mosquitoes rest easily after heavy rain.

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 Wadi Jaleel

New development: ongoing construction and vacant plots between the homes

New developments in valleys like Wadi Jaleel combine multiple problems: strong floods leaving ground waterlogged for days, modern drainage unable to handle flood volume, and new villas with low ground. Our treatment targets low-lying areas, gaps between villas and repeated water pooling after floods.

Questions about this district

Do floods in Wadi Jaleel carry mosquitoes from higher areas up the valley?

Yes, floods carry mosquitoes from higher zones and around Jabal Al Nour. Immediately after floods we treat pooling water and gaps between villas.

Is waterlogged ground for several days after a flood enough for a full mosquito breeding cycle?

Yes, one week of dampness supports a complete cycle. After predicted floods you need immediate treatment.

Do new villas have private drains or are they connected to weak public drainage?

New villas have private drains but they connect to a public system that may not handle strong floods. We treat pooling water around the villa first.

Does landscaping and irrigation in new villas increase the mosquito problem?

Some villas have small gardens and irrigation systems, adding to standing water. We focus on treating the garden if present and the ground around the villa.

How do I protect my villa from mosquitoes in a valley prone to constant floods?

We focus on treating low areas and gaps around your villa before the rainy season. We also use fine screens on windows and openings.

Is three-weekly treatment enough in a valley with this rate of flooding?

In rainy seasons you may need treatment every two weeks, especially immediately after floods. In dry seasons three weeks is adequate.

How much does mosquito control in Wadi Jaleel 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 Wadi Jaleel.
