The term 'mosquito barrier' can be broken down into two parts: a SCREEN and a NET. A SCREEN is a mesh material that is used to block out insects, while a NET is a fabric made of fibers woven together in a grid-like pattern. Both of these materials are used to create a physical barrier that prevents mosquitoes from entering a space. The combination of the two materials creates an effective barrier against mosquitoes, providing protection from their bites and the diseases they can carry.
