Why they keep coming back in Harat Al Baharah

Salt air and persistent moisture keep mud and popular buildings constantly damp, and cracks have widened over decades of exposure. The method is set out in full on the full Preventive treatment page.

The first reason

Sea humidity, salt and widening cracks

Salt laden air and high humidity crack mud and popular walls open, creating new pest entry points each season. Cockroaches and mosquitoes use these fissures to enter. Preventive treatment must track new cracks at every visit and seal them as they appear.

The second reason

The harbour and corniche as pest sources

The fishing harbour and the corniche supply insects and mosquitoes with food and water. Flies and cockroaches travel directly from the port into the quarter. Preventive treatment must apply a strong external barrier at the base of the outer wall facing the sea and harbour.

The third reason

Water, tanks and drainage runs

Water arrives by tanker and every home has a roof tank. Old tanks, broken drains and waste pipes supply standing water for mosquito breeding all year. This combination of moisture and stagnant water creates ideal breeding conditions.

Landmarks of Harat Al Baharah

Thuwal Harbour and Thuwal Corniche define the boundaries of the maritime quarter. Preventive visits arrive via the corniche road and follow the narrow lanes down to the base of the outer wall facing the sea and harbour directly.

Before treatment

What a preventive visit reads

The town sits directly on the Red Sea coast where the old fishing harbour and the maintained corniche border the quarter. Sea humidity stays elevated all year, water arrives by tanker so every household has a roof tank, and drainage systems are basic.

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

The base of the outside wall

The base of the outside wall at Harat Al Baharah facing the sea and harbour must carry a thick, strong, tall residual band because insects come directly from the port and corniche.

An exterior door threshold and the gap beneath it

Gaps and openings

Gaps and cracks in mud and popular walls are numerous and widened by salt and humidity, requiring continuous monitoring and sealing at every visit.

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

Air conditioning condensate

Air conditioning and refrigerator drains run onto foundations perpetually damp from sea moisture; water seeps around the base and every visit monitors these outlet points.

Floor drains

Floor drains in old coastal homes may be blocked or broken, allowing water to pool around the building and creating a mosquito breeding ground.

A drip irrigation line in damp soil beside planting

Irrigation against the wall

Watering on balconies and roofs supplies additional standing water, and damp roofs shelter insects year round. The programme monitors these spots.

A closed monitoring station at the foot of a wall

The monitoring points

Monitoring points in the quarter are placed densely on the sea and harbour facing side, and around every new crack and old opening because external pest pressure is continuous and high.

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 Thuwal Sub-Municipality

Thuwal sub municipality is a small fishing town on the Red Sea coast at the far northern edge of Jeddah governorate. Its old quarters are closely packed popular and mud built houses on narrow streets, with newer low rise concrete homes from the town's development programme beside them. Sea humidity stays high all year, the fishing harbour and the corniche form its seafront, water arrives by tanker so household tanks are everywhere, and the town sits on Wadi Thuwal, ringed by open ground and by the irrigated green campus of King Abdullah University of Science and Technology.

Questions about this district

The quarter is right next to the harbour. How does the programme protect against that?

The external barrier focuses on the wall base facing the sea and harbour where pest pressure is greatest. Monitoring points are set around openings and widened cracks.

Salt air cracks the walls open. Can preventive treatment address this?

Preventive visits track new and widening cracks and seal them as they appear. Large structural cracks may need separate building repairs.

The old roof tank breeds mosquitoes. What does the programme do?

Old, open and contaminated tanks supply standing water for mosquito breeding. The programme monitors the tank, screens it or repairs it as needed.

The quarter lanes are narrow and have standing water. Does this affect visits?

Yes. Standing water in lanes is a direct mosquito source. Visits monitor this and report to municipal authorities if needed.

My home is joined directly to the neighbour's. Do insects come through?

Yes. Tightly joined homes and shared cracks offer pest routes between houses. Preventive treatment focuses on sealing and protecting these shared gaps.

How often do preventive visits come to a damp coastal quarter like this?

Visits follow what monitoring points report and mosquito activity. A humid coastal quarter may need close monitoring, particularly during mosquito season.

How much does preventive treatment in Harat Al Baharah 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 Baharah.
