Apply the zappers para sells and find out if they kill them or not.
It would have to be an on the up and up experiment and proof, which means supplying all data so that the experiment could be duplicated by others.
It is you that are off the beam on this. It is a relatively simple thing to do yet it never crossed your mind or the paraperson to do this? Really?
Think of the sales! Through the roof IF proof was evidenced, and by that meaning proof that could be duplicated by sundry others interested in finding out whether or not a zapper is something of importance.

Draw your own conclusions.
