The second reason that I would to kill a termite is not only makes a problem for me but also makes a problem for agriculturist too. I think everyone knows that a termite is an important insect in economy. A termite doesn’t have a benefit but it is harmful too. Wongkaluang and Sornnuwut claim that “a termite is destroyer in ecology if has a termite over abundantly and it does choose destroy wood.”1 In my relative, my uncle has land to grow a rubber plant and he told me once about his rubber plant. His rubber plant was destroyed by a termite. A termite should destroy until internal a rubber plant became a hollow. He doesn’t know when his rubber plant was destroyed by a termite but he notice leaf change color to yellow leaf. Afterwards, a rubber plant is dying. Finally, he knows change color of leaf is a signal that root system of a rubber plant was destroyed. When I listening my uncle told, I feel angry instead him because it not only lose a rubber plant but also loss income too. I think one thing is kill by inject insecticide to a termite same in my experience. I think it is a best way to eradicate a termite.
