Shelly, it can hurt when you are bitten. Crazy little buggers. If they break the skin, wash your hands and disinfect the wound. I would be very careful scooping them up, you can break their ribs easily. If a gecko nips you, hold her firmly. Applying gentle pressure to her upper snout until she stops squirming and squeaking. Just be careful not to hurt her, be very gentle. A lot of handling is the best fix though.
