Preventive treatment in Tarwiyah, Makkah

Targeted, not broadcast

Told before we start

What we will use, where it goes, and what to cover or move before we arrive.
A follow-up visit

We return after the first treatment, because what survives it does not show on the day.
Homes and businesses

Apartments and villas, and kitchens and stores that need a record of each visit.

Why they keep coming back in Tarwiyah

Villas in early construction phases face high pressure from rodents and insects coming from the building sites and vacant ground surrounding them. The method is set out in full on how we approach Preventive treatment.

The first reason

Open building sites and vacant plots

Excavations, fill and ongoing construction provide safe shelter for rodents and insects, and the new villas nearby face constant pressure from these breeding grounds.

The second reason

Wadi Mudarraja carries moisture and flash floods

The wadi carries water and aquatic insects after rain, and the hillside slopes feed moisture into the building foundations very quickly.

The third reason

New external band under construction dust

New villas need a strong external band but dust and fill from building work quickly covers and weakens the residual layer.

The character of Tarwiyah

New development: ongoing construction and vacant plots between the homes

In a new development district the priority is protecting new homes from rodents and insects spreading from construction sites and vacant ground, and the programme emphasises a strong external band and intensive monitoring until the district stabilises.

Before treatment

What a preventive visit reads

Wadi Mudarraja runs beside the district and carries moisture and insects, and empty plots between the new villas shelter rodents and reptiles that need ongoing preventive attention.

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

The base of the outside wall

The base of the outside wall on new villas needs reinforced banding because dust, fill and insects from neighbouring building sites create constant pressure on the residual layer.

An exterior door threshold and the gap beneath it

Gaps and openings

Gaps and openings in new villas require tight sealing because active construction leaves new gaps from movement and work constantly.

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

Air conditioning condensate

Air conditioning condensate creates moisture on the ground beside the external wall, and construction dust mixes with damp to create an insect friendly zone.

Floor drains

Floor drains need regular treatment because dust and silt from building work and the nearby wadi collects there, and rodents search for water in this area.

Irrigation against the wall

Garden irrigation on a new villa needs careful direction away from the external wall because moisture from construction and soft footings is already high.

The monitoring points

Monitoring points on the footings, external corners and in garden areas track insects and rodents coming from building sites, vacant plots and the wadi.

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 Sharai Sub-Municipality

Al Sharai is the eastern growth front of Makkah along King Faisal Road and the Taif road. Settled quarters sit beside recently renamed schemes where plots are still vacant and buildings are going up, so construction sites, fill and open excavations lie next to occupied homes. Wadi channels such as Wadi Mudarraja, Wadi Al Sharai and Wadi Al Mughammas carry flash floods after rain and dry out to damp silt, while dust blows off the open hills. Roadside shops, restaurants and warehouses line the Taif road, and to the east the area shades into villages, palm farms and springs.

Questions about this district

Does a new villa need preventive treatment while it is still under construction?

Yes, the preventive programme starts in early build phases and prioritises the external band, drains and gaps before they become permanent insect entry points.

When does construction finish and rodent pressure stabilise in new districts?

District stability takes years after building ends, and the preventive programme continues to focus on entry points and gaps as long as neighbouring sites remain active.

Does dust and rubble from building sites damage the external residual band?

Yes, dust from construction covers the external band and weakens its barrier, so preventive visits include cleaning and band renewal as needed.

Does Wadi Mudarraja carry aquatic insects into the new villas?

Yes, seasonal rain carries water and damp loving insects from the wadi, so the external band and monitoring focus on the wadi facing side of each villa.

Should the preventive programme pause until construction is fully complete?

No, the programme continues through all construction phases but adjusts for building stages, with the external band and monitoring focusing only on occupied areas.

Do completed villas need extra monitoring points in their first year?

Yes, insect activity often rises in the first year after build completion, so the programme adds extra monitoring points until the district fully settles.

How much does preventive treatment in Tarwiyah 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 Tarwiyah.
