The Ladybug
They are fine with humans, not poisonous and they do not bite. During the night they disappear, but bounce back as soon as the sun hits the kitchen window.
If you enjoy having a vegetable garden every year but have a bad aphid or scale insect problem, then ladybugs can help - particularly if you are as fond of having several different varieties of tomatoes like we do. If you find that you lack sufficient numbers of them in your garden, or have a particularly bad aphid infestation, you can order live ladybugs online. They are delivered in a small box by the postal service. You can just release them into your garden and they will quickly solve the problem.
