This device attracts mosquitoes thanks to mosquito-irresistible UV light emitted by UV leds.

The beasts then get caught in the descending air flow created by a very silent Arctic fan, and they finally dry to death.

Only 4 bolts hold all the parts together.

No chemicals involved, no sound, ideal device for quiet nights and stingless outdoor dinners.

You'll need:

  • twelve UV leds, 5mm diameter
  • four 100 ohms resistors
  • one 12V 120mm Arctic fan ARCTIC F12 Silent (about $7 a piece on amazon
  • one 12V power supply
  • one small switch
  • one power socket
  • a piece of mosquito screen
  • four M4 bolts

I've mounted in parallel four groups of 3 leds, each group with one 100 ohm resistor so that if one led burns, the other groups won't suffer.
