The Venus flytrap is a plant that never loses its ability to fascinate, no matter what your age. Place the plants in any humid area with bright light---a window near the kitchen sink is a good spot. They prefer a form of neglect, performing better with no fertilizer and infrequent repotting. The plants are not known to suffer disease and are only really troubled by aphids.
A Venus flytrap is a wonderful decorative plant, and its alien appearance makes an interesting talking point for guests. The plants come in a variety of cultivars, ranging from pure green to pure red; there are some with only some red pigments and those approaching a black appearance. The traps themselves also vary. Some traps come with larger, serrated teeth and others with long, thin spines. Flytraps also produce flowers. A variety of plants can be kept in the same location, under shared conditions, or you can spread them around your home as you would any other houseplant.
Allow the plants to catch flies and insects indoors. According to East Texas Gardening---part of the Texas AgriLife Extension Service---the plants consume approximately two or three flies per month. You may need several plants to capture all the pests flying around your home. The Botanical Society of America reports that each trap can only close about seven times, while other sources estimate 10 to 12 closures before the trap reverts to only photosynthesis. You can capture insects to feed your plants, if there are few available nearby.
Venus flytraps can serve as a valuable educational tool. The plant's exotic, almost monstrous, look and reputation will enthrall kids and may help tempt younger children into an interest in plants. Not only can you teach principles of botany, basic plant growth and maintenance, but the Venus flytrap demonstrates the digestive process, the food chain and cycle of life and death---all played out on a small scale that is accessible to kids. The plants are considered easy to grow and maintain, and children can readily observe it in action. In locations where pets are not allowed or children are not yet ready for the responsibility of caring for one, the plant can help teach about the care and feeding of a living creature.
