Why would you want/need to? Presumably they're not doing any harm. They're quite possibly eating some other (lemon-tree-feeding) infestation for you. Have a close look and see what they're up to.
If you really must get rid of them, I'd guess allowing the plant to dry out (as far as possible without killing the plant) will force them to emigrate.
On a (vaguely) related note, I found one of my cactus thingies (no idea exactly what they are) completely infested by caterpillars, which were having a banquet. I left them alone to see what would happen. The plant was more-or-less stripped bare of leaves and the caterpillars cocooned themselves. Six months later, the plant is back bigger and better than ever before. Bugs aren't always
the big deal that people think they are.
