Is it worth treating a duplex for pests before construction starts in Najran? For most owners the answer is yes, because the cost of treating termites and rodents while walls are still open is far lower than repairing damage later. The centre of Najran sits about 1309 m above sea level, and the surrounding hills and dry ground can bring a range of pests to new plots. Termite treatment is typically priced at SAR 10–25 per m², rodent control at SAR 200–500 per visit, and bird control at SAR 30–80 per m. Budgeting for these services before the first block is laid lets you plan the work instead of reacting to a problem after the finish is applied.

A pre-construction visit usually begins with a walk-around of the plot and the foundation area to look for signs of activity, such as soil tunnels, droppings, nesting spots and gnawed material. The technician then checks the planned footprint of both units, including the party wall, service ducts and any areas where water may collect. Treatment is planned around what is found, and the technician will explain the likely method and cost for each part of the work. A follow-up visit is often needed to confirm the results, with a typical cost of SAR 100–250 per visit. Where the risk is ongoing, an annual pest-control contract at SAR 500–1,500 per month can keep the site monitored through the build and into occupation.

Before the visit, gather the site plans for both duplex units, the foundation layout and the expected construction timeline so the technician can judge where treatment should be applied. Clear access to the plot, including any stored materials or timber, makes the inspection faster and more thorough. Note any pests you have already seen on or near the land, and tell the technician whether neighbouring plots have had problems. Confirm whether the visit will be a single pest-control visit at SAR 150–400 per visit or a longer programme, and ask for the scope in writing before work starts.

In a duplex, the two floors often share lines, so tests are done floor by floor.
