Answer / pavan

A mosquito bat consists of three layers of mesh, the outer
two being one terminal and the inner being the other
terminal of a transformer that provides high current at low
voltage.

When a insect comes in between the two meshes it creates a
closed path for the current to flow. since it is a high
current it results in a sudden surge which creates a spark
that eventually ionises the air molecules in and around the
arc. this sudden ionisation of air creates the hissing
sound.
