Termite control in Harat Al Baharah Jeddah

Harat Al Baharah is an old quarter of Thuwal, a small fishing town on the Red Sea coast, with traditional popular houses and clay built structures tightly packed on narrow lanes. Sea humidity stays high year round and salt air is constant, water arrives only by tanker so household cisterns and tanks are everywhere and leak steadily. Termites find here the ideal combination: damp timber, aged foundations, and dense wall sharing between neighbours.

Why they keep coming back in Harat Al Baharah

Mud and traditional stone houses in the quarter are tightly packed, touching one another, and sea humidity penetrates all the walls equally, so when termites establish in one house they spread rapidly to every adjacent building. The method is set out in full on our Termite control service.

The first reason

Very high sea humidity and salt in the air

Harat Al Baharah stands only hundreds of metres from the Red Sea, and sea humidity never drops all year. Salt laden air dampens walls and timber from outside, salt water seeps around footings, and timber is perpetually wet. This is termite heaven and advanced timber decay.

The second reason

Mud and stone houses with ancient mortar and shallow bases

Traditional buildings in the quarter are clay and stone in very old mortar. The clay holds sea moisture tenaciously, ancient mortar is eroded and lets water pass freely, and footings are very shallow. Termites find easy routes through the clay and mortar to the timber above.

The third reason

Cisterns, tanks and continuous seepage

Houses in the quarter are not on piped water and depend on cisterns and tanks. These are old and leak, water seeps round their bases into soil and adjacent foundations, raising moisture permanently round each house.

Landmarks of Harat Al Baharah

Harat Al Baharah sits beside Thuwal Harbour, historically the town's fishing heart, and overlooks Thuwal Corniche, the waterfront maintained by Saudi Aramco. The old quarter is now neighboured by the sprawling modern campus of King Abdullah University of Science and Technology, reflecting the tension between maritime heritage and contemporary development.

Before treatment

The evidence that decides the treatment

An ancient coastal quarter very close to Thuwal fishing harbour, where sea humidity is high throughout the year and water arrives only by tanker, so household cisterns and tanks are numerous and seepage around them is constant.

Mud tubes

Mud tubes in Harat Al Baharah are deep in clay mortar and soft stone, sheltered by salt and damp, and often invisible on the surface where they would be seen.

Shed wings

Shed wings appear at cracks and joints in stone walls, marking the presence of old, large colonies living in the wall thickness itself.

Hollow timber

Hollow timber in the quarter is nearly universal, from floors and doors to structural beams, because sea humidity is continuous and relentless.

The water source

The moisture source in Harat Al Baharah is the sea itself, the salt air, seepage from ancient cisterns and tanks, and the saturated soil round the footings.

Cardboard boxes and timber stacked on a store floor

Cellulose on the floor

Cellulose on the floor sits in clay and stone foundations and timber buried in mortar, some of it very old and part archaeological.

Joints and pipe entries

Joints and pipe entries in this quarter are embedded deep in the old thick walls and need specialist application because ancient mortar allows easy termite passage.

How we work

1
Inspect and trace

We sound the timber and the skirting, take moisture readings, and follow the tubes to the point where they leave the soil. We also settle the species, because one that lives inside dry wood is not treated like one that lives in the ground.
2
Treat the soil around the building

A narrow trench at the footing and injection at regular spacing, so the treated band runs continuous with no gap to walk around.
3
Drill the joints, inject the timber

Small holes at spacing along the slab joints, the wall bases and the pipe entries, direct injection into the galleries inside the affected timber, then the holes are closed and made good.
4
Bait stations and monitoring

Stations in the soil carrying a slow-acting material the workers pass through the colony by mouth-to-mouth feeding, and we come back to read them, because an empty tube on a wall proves nothing on its own.

What termite control includes

A traced, recorded inspection

Sounding, moisture readings, tubes traced back to the soil, and the species settled before anything is applied.
A treated band at the perimeter

Trenching and injection at the footing, spaced so the band is continuous rather than a set of patches.
Joints and service penetrations

Slab joints, pipe entries and floor drains, which are the ways up through the concrete.
Bait stations in the soil

A slow material carried back through the colony by feeding exchange, rather than stopping the workers at the wall.
Aftercare instructions

What not to dig or water near the treated band, what to keep off the walls, and the ventilation time we set for your case.
Scheduled monitoring visits

Reading the stations, sounding the same timber again, and treating any new activity.

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

Why do termites spread so quickly between neighbouring houses in this quarter?

Houses are tightly packed with shared walls, and high sea humidity creates uniform damp. Termites move easily through old mortar and clay from house to house at speed.

Does the salt in the air and water affect the treatment?

Yes, salt affects the effectiveness of some products, so salt resistant formulations are chosen. Salt also keeps walls damp year round, speeding termite movement between buildings.

Could the old cisterns and tanks themselves be the source of termites?

Not directly. The tanks do not harbour termites, but their seepage raises moisture round the footings, which attracts termites from the surrounding soil into the house.

Is treating one house enough or must the whole quarter be treated?

Treating one house may require treating adjacent neighbours if they are infested. Shared walls and uniform moisture mean termites can move easily from the treated house back from neighbouring untreated buildings.

How often will I need retreatment in an environment this damp?

Regular monitoring determines the need. But very high sea humidity may mean retreatment every two or three years, especially if cisterns continue to leak.

Is there a way to reduce moisture round the footings in a coastal quarter?

Repairing cisterns and tanks is the first step. Adding horizontal drainage round the footings may help, but natural sea humidity will always remain very high.

How much does termite control 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.
