Gecko control in Harat Al Sarahin Jeddah

Harat Al Sarahin in Thuwal is an old quarter with mud-built popular houses where related families cluster together in the manner of coastal villages. The town experiences housing renovation and the old homes have abundant openings. Constant maritime humidity and architectural age mean the mud and timber are decaying and deep cracks shelter geckos.

Why they keep coming back in Harat Al Sarahin

Clustered families in close-built houses mean many shared openings between homes. Geckos move easily from house to house through shared gaps and narrow passages. The method is set out in full on the full Gecko control page.

The first reason

Decaying mud and timber and deepening cracks

Old mud houses deteriorate quickly due to high sea humidity. Cracks deepen and timber decays. Geckos settle in these deep and complex crevices. Treating them requires deep injection, not surface spraying alone.

The second reason

Sea humidity, salt and accelerated decay

Sea salt speeds decay of mud and timber. Constant humidity creates ideal conditions for insects and geckos. Weakened old buildings provide very easy gecko shelter.

The third reason

Family clustering and shared openings between houses

Tightly-packed houses have many shared openings between walls. Geckos move easily house to house. Treating a single house may not stop geckos coming from neighbouring homes.

Before treatment

The food, the opening and the crevice decide the method

The quarter is close to Thuwal Harbour and Thuwal Corniche with very high sea humidity. This moisture rapidly decays old materials and creates deep fissures.

The house gecko

House geckos in Harat Al Sarahin enter through deep cracks and shared openings between tightly-packed mud houses and settle in decaying timber and mud.

Outdoor lighting

Street lighting in the narrow quarter lanes provides limited light but geckos are active in darkness and high humidity.

Window mesh

Windows in old mud houses do not close fully and mesh is very worn. Repairing mesh and ensuring tight closure is essential.

Air-conditioner pipes passing through an outside wall

The air-conditioner sleeve

Air conditioning pipes in old houses may be open or damaged. Geckos enter through these gaps easily.

Meter boxes and electrical panels

Electrical panels and meter boxes in mud houses are surrounded by many gaps and cracks. These points provide easy gecko entry.

Green space is sparse in the quarter but sea humidity is very high. Geckos arrive seeking moisture and the insects that prefer damp conditions.

How we work

1
Inspect at night and find the source

We come at the hour it is actually moving, and establish which wall face it is living on, which lights are gathering its food, the entry points and the crevices it wedges into by day.
2
Treat the food source

We treat the flying and crawling insects on the wall faces, around the perimeter and around the lighting. Once the food goes, the wall stops being worth staying on.
3
Close the openings and clear the crevices

We seal the air-conditioner sleeve, screen the vents and drain outlets, deal with the underside of doors, and place a repellent in the crevices and behind panels so they move out before anything is closed.
4
The follow-up visit

We come back once the glued eggs have hatched, check the seals held, and re-treat any wall face where activity has returned.

What gecko control includes

A recorded night inspection

Wall faces, lighting, entry points and egg sites, all established before anything is applied.
Treating the insects on the walls

Targeted treatment around lighting, windows and the building perimeter, because the food is what keeps it there.
Placed repellent in the crevices

Behind panels, in wall joints and at the ceiling-void entries, where it sits out the day.
Screening vents and drain openings

Shafts, vents and the condensate outlet, which are entry points nobody looks at.
Aftercare instructions

Ventilation, what to cover, and the change to the outside lighting that stops the insects gathering again.
A scheduled follow-up

A set date after the first treatment, a check on the seals and re-treatment of anything still active.

The character of Harat Al Sarahin

Mixed district: shops at street level with homes above them

In an old coastal quarter like this, gecko infestation is not one house's problem but the environment's. Mud and timber homes have deep cracks and many shared openings.

Questions about this district

Does an old mud house need different treatment than modern buildings?

Yes, old mud and timber contain deep complex cracks. Treatment requires deep injection, not surface spray alone. Old materials need different formulations.

Does sea humidity reduce pesticide efficacy in Harat Al Sarahin?

Yes, high humidity reduces the efficacy of standard pesticides. We use formulations that withstand high moisture and apply thicker protective layers repeatedly.

Will treating one house stop geckos if neighbouring houses remain untreated?

No, shared openings between houses provide easy gecko transit routes. Coordinated treatment of several houses is necessary for lasting results.

Does proximity to the harbour mean more geckos?

Yes, the harbour provides abundant insects and humidity is very high. Houses near the port attract more geckos.

Will replacing old houses solve the gecko problem?

New building may reduce the problem as modern construction has fewer openings. But while moisture and insects remain, geckos will return.

Do we need repeat treatment in Harat Al Sarahin due to sea humidity?

Yes, sea humidity means pesticides lose efficacy quickly. Repeat treatment every month to six weeks is necessary.

How much does gecko control in Harat Al Sarahin 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 Sarahin.
