A mosquito control trap taking advantage of the normal stages of development for a mosquito. The trap including stagnant water trapped within a container by a weeping platform floating on top of the water. A series of holes in the weeping platform provide exposure of the water to form brood cups in which female mosquitoes lay eggs.
