Do electric insect repellers example work?

For context, I live in a rented house that has several of these installed. My personal observation is that they do nothing to repel bugs, but actually are effective at killing the bugs that enter the home — it just might take a day or two for the bug to die first. However, my personal observation may not be a typical result, hence the question: do these devices work? If it's a case of, "Yes... but", what do you need to look for to get an effective system?

  • @nico - Unfortunately, it could easily have been photoshopped. Or special effects (aka dirt/paint).

    Why is this a duplicate? The other question was about ultrasonic pest control devices. This one is an electromagnetic device (or magic rays, or something, considering that "creates a force field...by sending electronic pulses through the wiring"). Or does the text description ("other emissions") of the other question cover this?

  • @RexKerr Because that question contains the answer to this one.
