Preventive treatment in Al Bayban Makkah

Al Bayban is an old Makkan quarter perched on a hill north of the Grand Mosque between Al Diyafah and Al Hajun, a cluster of close-set stone houses and narrow lanes crowned by the five-storey Qasr Kuwair palace. The ancient foundations and lime-mortared stone walls are deep-cracked and porous, so insects have not entered from outside; they already live in the old stone. The preventive programme here stops insects moving outward from stone to living space, not the other way round.

Why they keep coming back in Al Bayban

The old quarter has narrow streets and tight spacing between buildings, which traps humid air. The base of the walls runs continuously wet. Humidity here stays high even in winter. The method is set out in full on the full Preventive treatment page.

The first reason

Porous stone and deep cracks

Old stone walls of local limestone and mortar have aged, become porous and fractured deeply. These cracks are perfect insect habitat. The external band must be thick and must penetrate these cracks as far as possible.

The second reason

Ancient sewerage and high moisture

The sewerage is very old and may be blocked or waterlogged. High moisture throughout the quarter attracts insects and rodents. The programme must first reduce moisture, then monitor and exclude.

The third reason

Tight streets and stagnant air

Streets are narrow and buildings are very close. Air stagnates. This creates very high humidity at foundation level. Insects and rodents prefer this damp, dark, still environment.

The character of Al Bayban

Historic district: close-set buildings, narrow lanes and ageing services

The old stone house means insects and rodents already live inside the stone and foundation, not just waiting to enter. The programme stops them spreading outward from stone to inhabited rooms and slows their movement through the quarter.

Before treatment

What a preventive visit reads

Foundations and walls date to the early twentieth century or older, built of local stone and lime. The stone has aged, become porous and fractured. These deep cracks offer shelter to insects and rodents year-round. Drainage systems exceed fifty years old and are saturated with moisture.

The base of an exterior wall where the building meets the ground

The base of the outside wall

The base of the old stone wall must carry a very thick external band and all large reachable cracks must be sealed or have monitoring points.

An exterior door threshold and the gap beneath it

Gaps and openings

Very fine cracks in the old stone may not seal, but tiny monitoring points must sit at them to read any activity.

An outdoor air conditioning unit with a condensate pipe on the wall

Air conditioning condensate

Cooler condensate from the old house may drain onto wet stone beside the wall, increasing moisture at the base.

Floor drains

Floor drains in the old house may be very old and not connected to modern sewerage. They may be partly open or unsealed.

A drip irrigation line in damp soil beside planting

Irrigation against the wall

Irrigation against the wall is light in this old quarter, but drainage and humid air provide enough moisture year-round.

The monitoring points

Monitoring points must sit at every accessible gap, at the wet base, and at every shared space with neighbours.

How we work

1
The baseline survey

We walk the outside boundary and then the inside: gaps under doors, pipe runs, vents, condensate lines, drains, the bin area and the store, and we fix the monitoring points before anything is applied.
2
Close the routes

Mesh on the vents, the gap under the door dealt with, the sleeve around a pipe run closed, and water put back into the drain nobody uses. Exclusion saves a spray that would otherwise repeat forever.
3
The band and the placed product

A residual band at the base of the wall outside and around door and window openings, with placed product inside joints and closed voids where it is warranted, and no open spray across living surfaces.
4
The scheduled visit: read, renew, record

We read the points to see which side is under pressure, renew the band where sun or irrigation has taken it, aim the visit at what the coming season opens up, and write down what was found and what was used.

What the preventive programme includes

A survey, then a check every visit

Entry points, moisture sources and storage, recorded before anything is applied and revisited each time.
Monitoring points that get read

At the wall and floor junction, under sinks and in the store, checked on every visit rather than only the last one.
A renewed exterior band

At the wall base and around the openings, put back wherever sun or irrigation took it between visits.
Drains, water lines and waste

The water seal in the drains, the condensate line and the ground around the bins, which are the standing water and food sources.
Between the visits

What to keep dry, what to keep closed, and what is worth a call before the next date. Ventilation we tell you before the visit.
A scheduled visit and a record of each

An agreed date, what the points held, what was treated, and what changed since last time.

What is different about Al Utaybiyah Sub-Municipality

Al Utaybiyah sub municipality covers the old districts north of the Grand Mosque: the hillside quarters of Al Hajun, Al Utaybiyah and Al Bayban, Al Zahir and Al Shuhada at the northern entrance, and the newer Al Zahra, Al Diyafah and An Nuzhah westward. Its building stock is among the oldest in Makkah, stone houses on the hills, packed apartment blocks and sewers decades old, threaded with crowded markets like the Utaybiyah souq and furnished flats that fill in the pilgrim seasons. Wadi Al Zahir and Wadi Al Tanim carry storm water through it, and industrial workshops line Hajj Street.

Questions about this district

Can a very old stone house be protected from insects and rodents at all?

Yes, but protection focuses on stopping outward spread from the stone, not removing insects already living in it. The external band and monitoring points are the solution.

Does high moisture and a constantly damp base reduce how well preventive treatment works?

High moisture increases pressure and may shorten the interval between visits. The programme may need weekly visits instead of fortnightly during damp seasons.

Do Qasr Kuwair and the old buildings around the quarter offer shelter for insects and rodents?

Yes. Historic stone buildings have deep foundations and many shelters. The programme may need extra monitoring points around these structures.

How often does the technician visit a house in Al Bayban each year?

Weekly in summer, every ten days in winter. High moisture means pressure stays high year-round.

Can all the deep cracks in the old stone be sealed?

No, some are too deep. The programme seals large gaps and leaves small monitoring points at very fine cracks.

If neighbours do not treat their houses, will my treated house be affected?

Yes. Insects move easily through shared cracks and close walls. Shared entries and stairs are quick highways.

How much does preventive treatment in Al Bayban 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 Bayban.
