Moskitier

A moskitier is a lightweight net or screen designed to prevent mosquito bites by forming a physical barrier between people and insects. It is commonly used over sleeping areas and to cover openings such as windows, doors, or room dividers. The primary purpose is to reduce exposure to mosquitoes and, consequently, to malaria and other mosquito-borne diseases.

Designs and variants include bed nets that drape over a bed, room-wide screens that cover multiple openings, and door or window nets that function as perforated curtains. Bed nets may be rectangular or conical in shape, while room screens are typically rectangular. The choice of design depends on the sleeping arrangements, the size of the room, and the location of openings.

Materials and construction typically involve lightweight synthetic mesh, such as polyester or polyethylene, with a fine weave to exclude mosquitoes. Natural fibers like cotton have been used historically but are less common today. The mesh size affects both protection and ventilation. Some nets are untreated, while others are treated with insecticides, most commonly pyrethroids. Insecticide-treated nets (ITNs) and long-lasting insecticidal nets (LLINs) are widely promoted in malaria control programs for their dual barrier and chemical effects.

Usage and maintenance emphasize proper installation to minimize gaps, tucking edges under a mattress, and keeping the net intact. Repairs should be made promptly to mend holes, and nets should be kept clean and dry when not in use. Moskitier are used globally, particularly in tropical and subtropical regions, as a practical means of reducing mosquito bites and associated disease transmission.
