Mosquito killer is a kind of mosquito-killing equipment that does not need any chemical mosquito-killing substances. It is a new generation of efficient and environmentally friendly mosquito killing equipment that absorbs advanced foreign technology and makes many technical improvements.

Because there is no need to use any chemical mosquito killing substances, it is a relatively environmentally friendly way to kill mosquitoes.
