For this, carefully scrape with a knife edge or other thin, straight edge object (such as a credit card) over the area to remove the stinger, if the person can sit still and it is safe to do so. Or you can take out the stinger with tweezers or your fingers. If you do so, avoid compressing the sack of the poison that is at the end of the stinger. If this sack is broken, more poison will be released.
