Although bees are helpful in terms of pollination, they can be deadly if you have an allergy to their stings. If you want to kill bees in your home or yard, consider using a natural remedy rather than a spray that is loaded with strong chemicals. You can make your own bee spray using inexpensive products that you may already have around your home.
Mix two cups of vinegar with two cups of warm water.
Pour the mixture into a clean, empty plastic spray bottle. Be sure to use a bottle that has a stream option on its nozzle rather than merely a spray option.
Approach a single bee cautiously and spray directly onto the insect.
Step on the bee when it falls to make sure that it is dead. Make sure you are waring appropriately soled footwear, of course.
Dispose of the bee carefully using a gloved hand or a dust pan, as the stinger can still sting you if you grab it.
