We are fond of flies, cockroaches and other insects which keep distrubing in life.
I have an idea for it - we have seen electric flies control all around which is connected to electricity when connected it will burn of. The idea is to have
laser sensors at the entrance of the house or restraurant which are not harmful to humans.
So by putting it in the entrance when the laser hits the insects, it dies. So easy measure to control pests and insects.
