While ladybugs are considered by many people to be a pestering type of beetle, ladybugs are helpful to our homes and gardens. Ladybugs eat a diet of small insects and aphids keeping us mite and pest free.
Ladybugs are considered defenders of your garden. They love to feed on aphids, which are plant lice. They also like to eat mites and small insects. If you keep a ladybug for a pet you can feed them raisins. You can find more information here: http://www.ladybuglady.com/gardeneaters.htm
