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. In order to develop through the larva and pupa stage the developing insects must enter the larger reservoir of stagnant water, since there is insufficient room in the brood cups. However, the holes are too small to permit escape of the adult mosquito, thus preventing any of the eggs from developing. This device provides a means for controlling mosquitoes without the use of pesticides and is especially suitable for use in lesser developing countries.

The invention discloses a photo-induction mosquito-removing device for inducing and killing mosquito larva outside, which comprises a cylinder body, an egg-laying chamber, a column, an insectarium, an eclosion chamber, an upper filter and a shield, wherein the column top of the egg-laying chamber is provided with a mosquito-induction opening, and the bottom wall at the bottom is provided with an air chamber; and the egg-laying chamber is inserted into the water from the opening of the cylinder body, and can float up and down. Rain enters the cylinder body through the upper filter on the top of the cylinder body, and forms flooded water in the insectarium and the egg-laying chamber. Female mosquitoes fly into the egg-laying chamber through mosquito-induction opening from the holes on the filter of the cylinder body, and lay and breed wigglers on the surface of the water. The wigglers are naturally active, and enter the insectarium through the meshes of the column for living. Because the temperature of the water in the egg-laying chamber is little high, the wigglers can not swim back and escape. The wigglers find food and pupate in the insectarium. The mosquito larvae begin eclosion into mosquitoes which are trapped in the eclosion chamber, and the breeding chain is cut off. The device can be arranged in a balcony or a garden. Besides, the cylinder body can be used for planting flowers or fishing. People not only can enjoy the joy of gardening, but also can control mosquito breeding, and can create a healthy and comfortable community.
