When the cells are ready, they start moving toward the top of your epidermis. This trip takes about 2 weeks to a month. As newer cells continue to move up, older cells near the top die and rise to the surface of your skin. What you see on your hands (and everywhere else on your body) are really dead skin cells.
Even More Fun Facts: 1  Because Ladybugs eat lots of aphids and other pest insects, many gardeners and farmers use them for pest control instead of chemicals. 2  A Ladybug can lay up to 1000 eggs in its lifetime. 3  Not all Ladybugs have spots.  Ladybugs will clean themselves after a meal.
One larvae will eat about 400 medium-size aphids during its development to the pupal stage. An adult ladybug may eat over 5,000 aphids during its lifetime (about a year). When not being used, ladybugs may be stored in the refrigerator, where they live off their body fat. (Keep the temperature between 35-45 F.) They appear almost dead in the refrigerator, but quickly become active when warmed up.
