Yellow jackets are insects that are similar to bees. They are also called wasps. Female yellow jackets are capable of stinging, and when they do, the person who has been stung can experience pain and have an allergic reaction. Furthermore, unlike bees, yellow jackets can sting several times and without provocation, thus making them a little more bothersome.
Some things you ought to know about yellow jackets...they are attracted to dark colors. They are also attracted to food and other scents such as perfume. If they are killed - such as when you squish them - a signal is sent to other yellow jackets in the nearby hive, and they can attack. The best thing to do is to avoid areas which have yellow jackets.
If you have been stung by a yellow jacket, however, you simply need to get out of the area so that you can immediately treat the sting. You may opt to remove the stinger from your flesh using a tweezer, but this may not be the best way as you might end up squeezing the stinger, which will result in more venom being injected into your skin. The best way to remove the stinger is to scrape it off using a butter knife or something similar. Even a credit card will do!
Once the stinger has been removed, make sure you clean the wound with warm soap and water. You can also apply an ice pack for 10 minutes at a time. This will help with the pain and swelling. If you can’t handle the pain, take over-the-counter pain killers.
