Ticks are small spiderlike animals (arachnids) that
bite to fasten themselves onto the skin and feed on blood. Ticks live in the
fur and feathers of many birds and animals. Tick bites occur most often during
early spring to late summer and in areas where there are many wild animals and
Most ticks don't carry diseases, and most tick bites don't
cause serious health problems. But it is important to remove a tick as soon as
you find it. Removing the tick's body helps you avoid diseases the tick may
pass on during feeding. Removing the tick's head helps prevent an infection in
the skin where it bit you. See Home Treatment for the
best way to remove a tick.
Usually, removing the tick, washing the
site of the bite, and watching for signs of illness are all that is needed.

Some people may have an
allergic reaction to a tick bite. This reaction may be mild, with a few
annoying symptoms. In rare cases, a severe allergic reaction (anaphylaxis) may occur.
Many of the
diseases ticks carry cause flu-like symptoms, such as fever, headache, nausea,
vomiting, and muscle aches. Symptoms may begin from 1 day to 3 weeks after the
tick bite. Sometimes a rash or sore appears along with the flu-like symptoms.
Common tick-borne diseases include:
Symptoms of a severe allergic reaction
(anaphylaxis) may include:
The sudden appearance of raised, red areas (hives)
all over the body.
Rapid swelling of the throat, mouth, or tongue.
Passing out (losing consciousness). Or you may feel very lightheaded or suddenly feel weak, confused,
A severe reaction can be life-threatening. If you have had a
bad allergic reaction to a substance before and are exposed to it again, treat
any symptoms as an emergency. Even if the symptoms are mild at first, they may
quickly become very severe.
Most ticks don't carry diseases, and most tick bites don't cause
serious health problems. The sooner
ticks are removed, the less likely they are to spread
Some ticks are so small that it is hard to see them. This makes it hard to
tell whether you have removed the tick's head. If you do not see any obvious
parts of the tick's head in the bite site, assume you have removed the entire
tick, but watch for
signs of a skin infection.

an area where Lyme disease is prevalent. Clearing leaves, brush, tall grasses,
woodpiles, and stone fences from around your house and the edges of your yard
or garden may help reduce the tick population and the rodent population that
the ticks depend on. Remove plants that attract deer, and use barriers to keep
deer—and the deer ticks they may carry—out of your yard. Treating yards with
chemicals that kill ticks (ascaricides) is sometimes effective but exposes you
and your pets to chemicals that may not be safe. You may choose to treat your
lawn for ticks with nonchemical or environmentally safe methods instead. Call
your local landscaping nursery or county extension office for more
