As
we transition into the summer outdoor activities, we need to be on the
lookout for the ever present tick in Wisconsin. Here we have gathered
some information to keep you informed on ticks, what to look for and
what to do.
It's all about the tick
Ticks
are tiny and flat and they are not insects. They are the largest of all
mites and have eight legs compared to the six legs of an insect.

How do they find me???
In
order for the immature nymphs and adults to get the blood they need,
they climb blades of grass or other vegetation and wait for a host to
walk by. When one comes near, the ticks can detect odors from the host –
like carbon dioxide, ammonia and lactic acid – and assume a "questing
position," clinging to the grass with two pairs of legs while holding
their front pair outstretched. When the host brushes against the grass,
the tick grabs hold and either attaches to the skin or wanders the body
in search of a thin-skinned area to attach and feed. That's when the
bacteria in their stomachs can be transmitted to a human host.

What to do if bitten by a tick:
- If you removed the tick soon after it is attached, chances are very small of getting Lyme disease. Also, not every tick is infected with Lyme disease bacteria.
- At the tick bite site, watch for an expanding rash that occurs frequently in Lyme disease for up to 30 days. Call your doctor if this occurs.
- However, it is common to develop an area of inflammation and itching up to the size of a quarter immediately after the tick bite due to the irritation from tick saliva and is not a symptom of Lyme disease. If the tick is infected, the expanding rash will appear later. Not everyone develops a rash, or it may go unnoticed. It is important to be aware of other possible symptoms of Lyme disease if you spent time in tick habitat.
Lyme Disease?
The
disease is highly seasonal, with over 80 percent of Wisconsin cases
reported from May through August. That's when most nymphs (which are
about the size of a pinhead) are feeding and when most people are
enjoying the outdoors.
signs and symptoms
Signs
and symptoms of Lyme disease can vary among individuals and not
everyone experiences all of the symptoms listed. It is important to
remember that not all ticks are infected with Lyme disease and transmit
disease. The tick usually needs to be attached for at least 24 to 48
hours and likely be engorged.
Common symptoms of Lyme disease to watch for after the bite of a blacklegged tick are:
Early Stage or approximately three to thirty days after exposure:
- A distinctive expanding rash occurs in 80% to 90% of cases, usually solid red or bull's-eye appearance at the site of the bite and persists for many weeks. Usually the rash is not painful or itchy
- Fever
- Chills
- Headache
- Muscle and joint pain
- Fatigue
Early Disseminated Stage or approximately days to weeks after exposure:
- Multiple rashes, not just at the bite site
- Facial paralysis on one side of the face
- Fever
- Stiff aching neck
- Headache
- Weakness and numbness or pain in arms or legs
- Irregular heart beat
- Dizziness, light headed or heart palpitations
- Persistent weakness and fatigue
- Abnormal pulse
Late Stage or weeks to months after exposure:
- Swelling and pain in one or more joints, usually the knee
- Problems with neurological or nervous system
- Persistent weakness or fatigue
Control steps
Here are some options to make your property less attractive to ticks and their hosts:
- Keep grass mowed.
- Remove leaf litter, brush and weeds at the edge of the lawn.
- Discourage rodent activity.
- Move firewood piles and bird feeders away from the house.
- Keep pets out of the woods to reduce ticks brought back home.
- Use plantings that don't attract deer or exclude deer through various types of fencing.
- Move children's swing sets and sand boxes away from the woodland edge and place them on a wood chip or mulch foundation.
- Trim tree branches and shrubs around the lawn edge to let in more sunlight.
From "Tick Management Handbook," Bulletin No. 1010, Connecticut Agricultural Experiment Station
State officials passed along a few steps that can help prevent tick bites and reduce the chance of getting tickborne diseases:
- Avoid wooded and brushy areas with high grass and leaf litter because ticks prefer these areas. Stay to the center of a trail to avoid contact with grass and brush.
- Use effective tick repellents and apply according to the label instructions. The U.S. Centers for Disease Control and Prevention recommends using repellents with 20% DEET on exposed skin and clothing to prevent tick bites. Adults should apply repellents to children, taking special care to avoid spraying in the hands, eyes, and mouth. Repellents that contain permethrin can also be applied to clothing.
- Wear clothes that will help shield you from ticks. Long-sleeved shirts and long pants are best. Tuck pants into the top of socks or boots, to create a "tick barrier." Light-colored clothing makes ticks easier to spot.
- Check your body frequently for ticks, and remove them promptly. Blacklegged ticks are small and may be difficult to find, so careful and thorough tick checks must be done on all parts of the body. It is important to pay special attention to areas where ticks tend to hide, such as the head, scalp, and body folds (armpit, behind the knee, groin). Take a shower or a bath as soon as possible to remove any ticks that may still be crawling on you.
- Remove attached ticks slowly and gently, using a pair of thin-bladed tweezers applied as close to the skin as possible. Folk remedies like petroleum jelly, nail polish remover, or burning matches are not safe or effective ways to remove ticks.
- Protect your pets from tick bites by checking your dog or cat for ticks before allowing them inside. While a vaccine may prevent Lyme disease in pets, it will not stop the animal from carrying infected ticks into the home. Speak to your veterinarian about topical tick repellants available for pets.
- Landscape homes and recreational areas to reduce the number of ticks and create tick-safe zones by using woodchips or gravel along the border between lawn and wooded area. Continue to remove leaf litter and clear tall grass and brush around houses throughout the summer.
diagnosis and treatment:
- Contact your health care provider if you suspect Lyme disease. Your health care provider may perform blood tests, a physical exam and check on your history of exposure. A blood test is not necessary for diagnosis of Lyme disease if the characteristic rash is present at the time of your visit. The blood tests are important if you have been ill for more than one month. The blood tests may be negative for two to three weeks after exposure.
