Anti-escape insect net

The invention discloses an insect net which can effectively prevent insects from escaping. The net is made of a 40-80-mesh stainless steel screen, thereby being ventilating and light permeable and convenient to carry over. Compared with an ordinary nylon net, the insect net can prevent coleoptera insects, such as longicorn beetle and biprestidae, from biting through the insect net to escape. When the insect net is used as a container for holding wood fragments or insects, the opened sides of the stainless steel screen are sewn together so as to ensure that the insects in the net do not worm out or bite through the net to escape; the rest side is sewn by using an invisible zipper, thereby preventing the insects from biting through the zip to escape; and moreover, the size of the net can be determined according to the specifications of the wood fragments. The net has the ventilating and light-permeable function and is convenient to carry over, and various insects are prevented from escaping.
