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.

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. You need to change its water every 2-3 days, rest leave all to solar trap.
2) Caterpillars do damage, how it is effective against them?
Caterpillars born from egg laid by moth / flying pest. As it traps the flying pest, it will break the life cycle of pest. The more the number of pest solar trap killed, less the number of pests remain alive in your field to lay eggs and lesser will be caterpillars.
3) Do I still need to spray pesticide after using solar insect trap?
a. It depends on crop to crop. As the solar trap is effective against some genera of insect, you may still need to use insecticide or other type of traps for complete control, like solar trap is not used for fruit fly, you need to use pheromone based fly trap, it is not effective against mealy bugs/ aphids/ jassids, if your field is infected with these pest also, you may need to spray pesticide or take recommended measures to control these pest.
4) What is the life of solar trap?
a. Solar traps have long life. Its solar panel have life of 25 years, whereas its light and battery have life of 3 years, based on the use, you may need to change its battery of light, we have all the spares available, and you can contact us to purchase spare parts.
5) Do I need to switch it on daily?

a. No, it is only for agriculture use. Please do not install it at home
7) How many solar traps are required for my field?
a. It has coverage area of 2 acer ( 50 m radius). Based on your field size and shape you can stall.
8) It has height adjustment, what is the use of that?
a. Solar trap needs to install at 1 feet above the canopy, you need to increase its height as crop height increases. For fruit crop install it in open space.
9) Does it trap honeybees or any beneficial insect?
a. It does not trap beneficial pest, as it works during the time when the harmful pest is active. Honeybees are not nocturnal insects.
