Honey bees are attracted to sugars, and may be especially attracted to liquid sweets. This is why they may be seen at your picnic or backyard buzzing around your watermelon, soft drinks or frozen treats. While bees are usually not aggressive when foraging for food or water, they can sting when disturbed, which can make them unwelcome guests. While your sweet treats may be attractive to bees, most bees use pollen and nectar as a food source. Worker bees gather both pollen and nectar from flowers to feed to the larvae and other members of the colony. Nectar is a sweet fluid produced by flowers to attract bees and other animals.
