Why Are Bees Attracted to Porch Lights?

Most people have seen bees buzzing around a porch light at night. Bees and their relations often conjure up thoughts of painful stings, but before you attack with a pesticide, remember that these insects are among the most beneficial bugs known to humankind. Without these pollinators to ensure the propagation of flowers and fruits, our planet would be a hostile place.

Honeybees are social and live in an organized community.

Identification

A wasp's sting is more painful than that of a bee.

Honeybees and yellow jackets are both part of the large insect order Hymenoptera. While bees and wasps may belong to the same family, they differ in important ways that make it easy to tell them apart. The expression "wasp waist" comes from the fact that wasps have a narrowing in the center of their body where the abdomen attaches to the thorax. Bees are rounded without this "waistline."

Distribution

More than 25,000 species of bees have been identified. They are located in every country, on every continent, wherever plants and pollen can be found. Many of these stinging insects live in organized colonies with a division of labor. Some insects live in hives that persist for decades, while others start from scratch each year.

Benefits

Honeybees are among the most appreciated animals in the Hymenoptera family, producing about 200 million pounds of honey each year in the United States. Wasps and hornets are also useful as they feed their young undesirable bugs, while myriad species of small wasps prey on destructive insects. Most important is the role of the "stinging insect" family as pollinators of flowering plants, including fruits and vegetables.

Attraction to Light

Bees and wasps are attracted to light--including a porch light if they are out of the hive when it is illuminated. While bees usually do not fly at night, if a predator has disturbed the hive, they might come out and head for the porch light. Because wasps tend to fly later in the evening than bees, the insects buzzing about the light are more likely to be wasps.

Prevention/Solution

Although the stings of bees and wasps can be painful, they are rarely a threat to human life. Most of the 50 to 100 people who die annually from stings are allergic to venom. Emergency epinephrine injection kits are available by medical prescription. Limit the risk of getting stung by leaving these insects alone.
