Ticks are bloodsucking parasites that hide in trees, grass, and plants, and feed off of hosts. They are technically related to spiders, although they are a very distant relative. They have hard shells and the ability to completely numb their hosts, and so both humans and pests can go for months without realizing they have a tick. Ticks can also spread itchy bites and disease.
Female ticks lay thousands of eggs, only to die right after. Their eggs are so small they look like specks of dirt or poppy seed crumbs. They are often brown in color. Baby ticks feed off of a host larvae immediately after being born. When they become juveniles they must feed again, and when they finally become adults after about 10 days, it will become an adult tick, which will continue to require feeding.
Ticks can bite without you knowing, and are especially risky for pets and children that may not be able to share their symptoms (if there are any symptoms at all). The most common symptoms are itching at the spot of the bite. Ticks can also carry diseases, most notably Lyme Disease which can cause brain damage if left untreated. Ticks numb the body, and can be very difficult to remove. Even after removal, pincers may remain in the host.
Ticks can bite without you knowing, Ticks rarely go into homes. You can prevent ticks by using tick prevention chemicals on your pet, wearing more clothing, and possibly mowing your lawn to give ticks a less ideal environment for hiding. Unfortunately, tick attacks can still occur.
