What happened to the promised mosquito killing laser?

It's been twelve years.

It’s a prime example of unnecessary complexity and risk. You get comparable results from a box fan pointed at a wire screen (mosquitoes get trapped on the mesh by the airflow), but nobody writes breathless articles about a box fan.

You can install a mosquito killing laser outdoors and have a large area of no mosquitos. How effective is a fan for that use case?

Given that the laser is pure vaporware, I’d say it’s infinitely more effective.
