Working Principle Insect traps are used for trapping harmful nocturnal pests in agriculture and horticulture crops. Solar insect trap devices use a different type of lights, like, UV, yellow, mercury to attract pest toward light sources, UV light is one of the most effective types of light for attracting pest toward it. Hectare solar insect trap is also based on UV light.  Insect files toward the light source and hits its flaps and fall in water tub beneath it.  Water tub is filled with water, which makes it difficult for insects to fly back. Any agent, like detergent, shampoo or kerosene can be added in water tub to reduce the surface tension of water.   How it works Solar insect trap contains  solar panel , battery, light and circuit for automation, water tub and stand. Solar panel charges the  battery during the daytime. Its software allows solar trap to start automatically after sunset and regulate the timing of solar trap.   Where it is useful Solar trap is useful for control of nocturnal pest.  There is different type of traps which are used against different pest, so it is very important for farmers to know which pest are attacking the crop and which traps are going to most beneficial. Solar trap is effective against the nocturnal pest, which flies during the night-time. Below is the brief list of pest where solar trap being useful. We have tried our best to compile the list, still it is not complete list and solar trap is effective against other pests also. You find in page or CTRL+F to find details of particular crops or pest.

FAQ

1) What are the other expenses of using solar insect trap? It is a product which does not have any other expenses once you purchase it.
