Description

mosquito larva trap

technical field

The utility model relates to a mosquito larva trapper.

Background technique

Mosquitoes bite and suck blood and transmit diseases. The World Health Organization has identified mosquitoes as "public enemy number one that threatens human health." A female mosquito lays eggs six to eight times, and can lay eggs to produce 1000-3000 mosquitoes. Mosquitoes go through four stages in their life: eggs, larvae, pupae, and adults. The life cycle is 1 to 2 months. The development of the three stages of egg, larvae, and pupae must be completed in water. During this period, they must rely on the water surface to breathe. When there is movement, it dives to the bottom of the water and usually wanders in the water. Therefore, stagnant water is a breeding ground for mosquitoes to grow before they become adults. "Clear stagnant water and kill mosquitoes" is often seen on TV, newspapers, the Internet, and community bulletin boards. It is regarded as the most effective measure. Catching and killing more than 1,000 mosquito larvae is better than chasing and killing more than 1,000 mosquitoes that are already flying in the air. Mosquitoes are much easier and more effective. Clearing stagnant water to kill mosquitoes is the key to preventing dengue fever. However, although the accumulated water is constantly cleared, it is difficult to have a good effect. The accumulated water can never be cleared completely, and mosquitoes can always find the accumulated water. Therefore, only by placing the mosquito larva trapper while clearing the accumulated water, can the mosquito killing effect be achieved.

In the long-term struggle with mosquitoes, human beings have invented various mosquito-catching and exterminating products such as mosquito nets, ant-proof screens, mosquito coils, aerosols, electric mosquito swatters, mosquito traps, and mosquito killer lamps. It is used in a small space and cannot be used on a large scale. Moreover, due to the characteristics of the product itself, most of them have disadvantages such as large pollution and high cost.

Patent No. 200820026677.2 discloses a simple fly and mosquito trap. This utility model uses the cone-shaped principle to catch mosquitoes and flies, but it needs to place food or have ultraviolet light to trap. Frequent food or power supply is required, which is inconvenient and expensive. Not conducive to large-scale promotion.
