This is a great idea and an interesting read!
I like the idea of a pump-res-light combo.
The problem I see with this is that if the bug is not in the presence of the light for long enough it could survive and mutate and become UV resistant. The only way I can think of to solve this is to have a large light container so that the water/bugs slow down and spend long enough in the light's presence to die completely. A problem considering that these things are already big.
A container with a mirror interior surface will probably help as the light is then reflected back into the water , to do more work, rather than absorbed by the container walls. Dont know how to make or where to find something like that.
Another potential problem: Having the pump in the presence of the light could pose a problem as the plastic they are made from may not be UV resistant. Unless its an outdoor pump maybe.
Keep up the good work!
