When treating bites and strings you should use?

If the insect’s stinger is still embedded in their skin, remove it by gently scraping a flat-edged object, such as a credit card, across their skin. Avoid using tweezers to remove the stinger, since squeezing it may release more venom.Wash the area of the bite with soap and water.Place a cold compress or ice pack on the area for about 10 minutes at a time to help reduce pain and swelling. Wrap any ice or ice packs in a clean cloth to protect their skin.Apply calamine lotion or a paste of baking soda and water to the area several times a day to help relieve itching and pain. Calamine lotion is a type of antihistamine cream.
hope this helps :D
