Annoying Insect

Its past midnight now and im still feeling annoyed. There is some kind of insect that has been making a loud noise comming from outside my window. I went out to my garden and tried to track its whereabouts and I closed in on the bamboo trees. Its in the bamboo but its too dark and the plant is too dense for me to see anything. Insecticide does'nt seem to work on it coz I cant pin point the exact location and shaking the tree only shuts it up for awhile. But once it stop I can feel the sense or relief never felt before. I really hope daylight will come and some heroic bird will have the annoying insect for breakfast. As they say, the early bird catches the insect in the bamboo.
