Yellow jackets are normally very slow to sting, but they are also very territorial. If the entrance to their nest is approached, they will become very aggressive. They can sting multiple times, and their stings can be very painful. People who are allergic to their venom could have a severe reaction, and it is possible to become hypersensitive to yellow jackets after being stung. This sensitivity could cause a serious problem if stung again in the future.
It is very important, if you believe there is a yellow jacket nest on your property, to call a pest professional. Attempting to remove the nest without a professional could result in being stung or driving the insects into your home. Proper removal requires special equipment and safety precautions and is best handled by a professional.
