Picture a wire, electrons enter one end as they leave the other. If there is nowhere for the electrons to move to, they don’t enter the wire. Probably the same for the bugs.

Electrons drift in the wire until the electric field is neutralized. If the “wire” is a chunk of doped silicon, electrons can enter one end and exit the other, however energy has to be added in the form of light.
Think of the electrons as doing the “WAVE”. The “WAVE” travels much faster than the electron.
