Reminded me of a story my dad had told me which occured in the 60s .... ad in paper ... mechanical mosquito killing machine/device ... 50 rs only... money order to be sent... what was sent was a punching machine like device , worth 5 bucks with instruction manual which said place the mosquito in so and so place and press hard , mosquito will be crushed to death... a lot of people complained and that person agreed to fight it in court but then disappeared...
May be this solution would have been useful now...... along with the trap
