The only way to get rid of bugs is to kill them. The fastest way to kill them is with some kind of spray. I tried 3 different ones that didn't work before I tried azamax. There are lots of things you can get at most supermarkets that might work. Depending on the type of bug you have you can look into natural predators, lady bugs are a good one.
A description of the bugs and what they're doing to your leaves would help.
