If you want to make the sunshade net play the role of insect control, you must choose the appropriate specifications, which are generally calculated by the number of eyes. If the mesh size is too small and the mesh size is too large, it will give insects the chance to drill in, but if the mesh size is too large and the mesh size is too small, the sunshade effect will be damaged and the cost will be increased. So it is the most important thing to choose the appropriate size of shading net when using, and the color is mainly white. Secondly, when covering, don't cover it in the daytime and uncover it in the evening, so it can't prevent insects at all.
If you want to prevent insects, you need to cover the whole process, and add a pressure wire above, to prevent the sun screen from being blown over by the wind.
