are all bugs on the bonsai bad? I just brought home my first bonsai and i can see bugs on it, small ones. I've roughly identified them as vine weevils but im not sure because im a noob. I just tried to get a picture of one because they were all over the place earlier, but now i cant find any cuz the sun went down i think, anyway, does anyone have any simple advice on how i can save my bonsai from insects? does insect spray work well?
