Mosquito Eradication idea

Mosquito menace is on the minds of billions of people around the globe, and is on the rise. Untill now, almost all the domestic solutions available, to my knowledge, are designed to repell mosquitos. This is actually not doing anything to eliminate them. The spray of disinfectants by municipalities actually harm humans more, and prepare mosquitoes to evolve stronger to survive.
I have been thinking why should we not think away from convention and design something that will actually attract and kill mosquitoes, similar to the fly & insect killer devices. This way we can make sure, the mosquitoes do not go back to the breeding grounds. The device can have something similar to a human organ (hand) with blood like fluid inside. Funny it may sound, but who knows it may become a stimulant for further research.

Nailcutter improvement/innovation

While cutting nails, the biggest concern for me is to prevent the flying nails from spreading across the floor/table. A partial side-blockage on both sides of the exits will solve this problem. I wonder why even the top manufacturers never improved on their products.
