Ticks are parasitic spiders that get their food from the blood of mammals, birds, reptiles, and frogs, among other animals. Trees and bushes are good places for ticks to hang out, and they like to stick themselves to people and animals that brush against them.
Ticks and their young can spread a number of dangerous diseases. They can also sometimes cause allergens and anemia.
Insect pests go through either easy or complex metamorphosis to finish their life cycle. In complex transformation, an insect changes from an egg to a larva (also called a caterpillar) to a pupa and finally to an adult.
