[header] How to take care of a wasp sting [title] Remove the stinger if necessary. [step] If the stinger is still in place, remove it immediately by scraping over it with a blunt object, such as a credit card or fingernail. You can also remove it with tweezers or pliers, but try not to squeeze the venom sac, as this will cause more venom to be released. 
[substeps] Only remove the stinger if the person can remain still. Young children or babies who have been stung may be too fidgety to safely remove a stinger.
