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 I'm not sure because I'm 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?
