1, after being stung, first of all, we should find the location of the sting and observe whether the stinger of the wasp has been left into the skin, and if it has, we should pick out the stinger right away.
2, if the wound is red, swollen and painful, then we need to take measures. The wasp's venom is acidic, so it is best to rinse it with alkaline solution if possible, such as: baking soda water, soapy water, low concentration of alkaline water and so on.
3, if there is no alkaline solution, with a lot of clean water rinse can also play a dilute venom the same effect.
4, If clean water is not available in the field, fresh urine will also work because urine is sterile.
5, in the wild you can also use fresh dandelion, purple flowers of the ground cleaned and broken coated in the stung parts, these herbs work very well.
