Mosquito control in Jarwal, Makkah

Targeted, not broadcast

A follow-up visit

Why they keep coming back in Jarwal

Seasonal guests fill flats completely then depart, leaving small puddles behind after quick cleaning that does not reach every corner or void beneath the floor. The method is set out in full on the full Mosquito control page.

The first reason

Shared entrances and damp surfaces

The old apartment blocks have shared entrances, dark staircases and below ground voids where air conditioning water, laundry and cleaning runoff accumulate. Adult mosquitoes rest in these voids during the day before flying to feed at dusk, using the same stairwells the residents climb.

The second reason

Standing water between repeated storeys

Each floor mirrors the one below it, but drainage outlets and pipes vary slightly from storey to storey. Water gathers in places invisible from a window and sits there for days after guests move out and before new ones arrive.

The third reason

Mosquitoes from the mountain and ancient paths

Jabal Qaiqaan sheds its water through historic flood channels that still function after rain, and mosquitoes breed in the wet voids at the base of the quarter before climbing to the upper flats.

The character of Jarwal

Apartment district: residential blocks, repeated floors and shared entrances

In this apartment quarter now filled with seasonal hotels, mosquitoes do not breed in a single room but in the shared voids and passages shared by dozens of units. Treatment must cover the entire block at the same time, not one flat alone.

Before treatment

Standing water and shade decide the method

The district sits between Jabal Qaiqaan to the east and Al Taysir Street to the west, and old flood paths still carry water down from the mountain towards the mosque during the rainy months.

The daytime biter

The daytime biter in Jarwal rests on the walls of shared entrances and the dark voids below ground where air conditioning and laundry water pools permanently.

The one that comes out after sunset

The one that comes out after sunset emerges from below ground voids and floods the shared staircases and corridors, entering every flat above through windows and gaps around pipes.

Air-conditioning condensate

Air-conditioning condensate in old blocks drains into shared channels below ground that have no proper ventilation, creating a permanently damp breeding ground.

The tank and its openings

The water tank on the roof or high floor may be a source if uncovered, but the main standing water in Jarwal comes from daily drainage and runoff, not from tanks.

Garden containers and irrigation

Gardens and irrigation are almost unknown in this crowded quarter, but broken pipes beneath the flats provide water enough for rapid breeding.

The shade it rests in

The shade where the mosquito rests in Jarwal is the shared entrances, narrow passages between buildings and the airless voids below ground where sunlight never reaches.

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.

What is different about Al Ghazza Sub-Municipality

Al Ghazza sub municipality wraps around the north and west of the Grand Mosque, from Al Shamiyah, Al Qararah and Shaib Amir round to Jarwal and Al Taysir. Large tracts were cleared for the northern expansion and the Rua Al Haram scheme, leaving excavated ground and open construction sites beside ageing blocks that now serve as dense seasonal lodgings in Jarwal and Al Taysir. Old flood paths still fall from Jabal Qaiqaan and Jabal Khandamah towards the mosque, and markets and eateries crowd Al Masjid Al Haram Road and Umm Al Qura Road.

Questions about this district

Are the ground floor hotels the main mosquito source feeding the whole block?

The hotels below produce water constantly from cleaning, laundry and plumbing. But mosquitoes climb to upper flats through shared entrances and gaps around pipes, so treatment must cover the entire block and all the voids between the storeys.

If I treat my upper flat, will that stop the mosquitoes coming up from the hotels?

Treating your flat alone will not stop them if the hotels below have not been treated. Mosquitoes enter through shared voids and around window frames. Effective control starts from the foundation and the common spaces.

Is standing water under the building hard to reach in old apartment blocks?

Yes, the below ground voids in these old buildings are dark and cramped, and water collects there from pipe drainage and general damp. These voids must be treated with direct spray and a residual on all surfaces.

Do the seasonal guests carry mosquito eggs from room to room when they leave?

Luggage and clothing carry eggs and nymphs between flats. Rooms that empty and refill days later hold standing water that hatches while the flats await new guests, and the cycle repeats.

Does the ground floor hotel need separate treatment from the flats above it?

The ground floor produces far more water than the flats above it, and guests bring mosquitoes in from the street and neighbouring hotels. The ground floor may need treatment weekly and the flats above every two weeks.

Is one treatment for the whole building enough or do we need repeated treatment all year?

Blocks this dense with constant water need regular treatment. During the Hajj and Umrah seasons, weekly or fortnightly visits may be necessary, and monthly treatment during quieter periods.

How much does mosquito control in Jarwal 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 Jarwal.
