Lice beding spray should work fine. Spray the bedding and around the cage, I would repeat again in 2 weeks or so to make sure all the eggs are dead. There are different method you can use to get them off him to give him some relief, I don't remember them off the top of my head, but I know you can let him soak and it should drowned most of them. Good luck getting rid of them, hope there isn't too much wrong with the poor thing.
