Probably large ones like the Fi-Shock 7000. Wall of plasma when they get swarmed. From the distance they sound like someone using an electric weed eater! :shocked:

This is true. Mosquitoes generally ignore the photomagnetic spectra of the attractant lamps. However there are baiters
available that do attact mosquitoes to the grid for elimination. They require frequent changing and their effectiveness
is hampered by rainstorms - when you need it most thereafter! Get a decent way to bring in the bugs and you have a
certain winner there!

Fine, tell us what you know of starships. 😛
They don't exist.

I made my own when I was about 14. I used some wire mesh and a transformer from a microwave oven. Now if I could just figure out how to put the magnetron into such a device that would actually cook the insects from within 🙂
MOTs with no current limiting and 2kV@500mA secondaries would not make a very good zapper. The voltage is too low for
effective breakdown with smaller insects and the current is way too high for the arc to be quickly extinguished. Even
if effectively ballasted the voltage is too low. This was one of the reasons why the Weber zapper although very well
constructed - clogged frequently. Its transformer voltage was around 3.6kV (OCV) and thus had screen type electrodes.
Sears brand had the highest voltage for consumer units at 5.6kV. They also had the most complaints for noisy eliminations too!
RE: Magnetron... Microwave radiation would not be very effective for insect extermination. The dwell time is just too high unless you have a small cavity to get irradiation levels up there. Then you have a cleaning issue to deal with as well as high power consumption. Of course the geek factor would be high!
Finally here we have a cockroach walking between two pads connected to a 2kV 500mA 50Hz source. BAM!
