This is a bit offtopic,
but does somebody know,
how such an electronic bug zapper works ?

Are the bugs killed just by one polarity of high voltage or are both poles there on the tennis rack mesh ?
hi-
I think both poles are there on the tennis racket. I took one apart recently but I forget just now which was positive and which was negative.
you can get the same thing from harbor freight for about $3 when they are on sale.... I have one and it works very well especially on those aggravating wood boring bee's which we seem to have an excess of around here. One slight tap and no more wood bee.

How do they do the insolation between plus and minus wire mesh ?
How close is the mesh ?
Do the insects get stuck between both plus and minus meshes and
get an electrical shock ?
On my zapper racket, there are 3 screens. The center one is negative and the outside two are positive.
The gap between screens is about 3 mm. The bug has to touch one of them and only be 'close enough' to the other and "ZAP" they're toasted.
The screens are supported and seperated by some kind of plastic material and the air between them.
When the space between screens is reduced to around 1.5 mm and the bug is touching one of the screens then the arc happens.
We can touch the outside of the screen and not be zapped.
So the bug makes the shortcut between plus and minus
high voltage and is toasted in the arc then ?
Thanks.
Yeah, it looks that way.
The bug need only touch one side and be "near" enough to the other and then he is cooked in the resulting arc.
