Can you have a pet ladybug?

Yes but you should know how to care for one. If you really like ladybugs, learn about them and you will realize that they are happiest in their natural habitat. They are predator insects that eat aphids and other insects considered to be pests. For this reason, ladybugs have been exploited by humans and taken from their natural homes and hibernation places by the millions and sold to garden shops and nurseries. There are ways to attract them naturally to your garden. Here's one site with more information about ladybugs. http://everything-ladybug.com/ladybug-facts.html
