Prevention Tips

Strategies to reduce the risk of exposure

Who is at risk for Lyme disease?

Outdoor workers, gardeners, campers, hikers, pet owners, people who hunt, fish, golf, or picnic in parks, and children, including those on school sponsored outdoor activities are at risk. Children are especially vulnerable since they run and play without caution.

Deer bring ticks into your yard, so reducing deer populations can help in lowering tick numbers. Birds and other animals also transport ticks. Mice are a primary reservoir for Lyme disease as well as a number of disease-causing microorganisms and often have many deer ticks attached to them. A tick seeking a blood meal will attach to a mouse, feed, and become infected. Other infections transmitted at the same time as Lyme disease may include Anaplasmosis, Babesiosis, Bartonellosis, Ehrlichiosis, Powassan Fever, Mycoplasmosis, Rocky Mountain spotted fever, etc. Ticks are described as a cesspool of disease. The spring and summer months are the prime time for Lyme; however, you can be bitten year-round. Ticks seek a blood meal anytime the temperature is high enough for them to be mobile, even with snow cover.

Personal prevention tips

Avoid sitting on the ground, stone walls, woodpiles or fallen logs, use an impervious ground cover, e.g., Gore-Tex®. Walk in the center of well-maintained trails, avoid contacting brush along trails, and do not use deer trails. Periodically check for ticks while in tick-infested areas. Deer ticks like cool, moist environments, such as leaf litter, tall grass, and the edge of yards, playgrounds, wooded areas, or roadsides. Many infections occur within the home yard if bordered by deer-inhabited woods.

Outdoor clothing

Wear light-colored long pants, long sleeved shirts and closely knitted socks. Tuck shirts into pants and tuck pants into socks. This will prevent a tick from crawling under clothing. Wear a kerchief and hat to protect your neck and head.

Rynoskin™ underwear is made from a knitted breathable stretch fabric that ticks have difficulty penetrating. It is reportedly helpful for hunters and anyone outdoors when the weather is cooler. Available in long sleeved tops, long bottoms, socks, hoods, and gloves. Available from

After returning indoors

Immediately perform a careful tick check. Deer ticks are tiny and difficult to see. If possible, have someone else inspect you. Be sure to check your hairline and where clothes fit tightly. Parents should check children. Shower promptly using a washcloth to remove unattached ticks. Remove attached ticks immediately using fine pointed tweezers or tick- removal tool. Grasp tick close to the skin, pull gently straight out. Do not use petroleum jelly, alcohol, soap, lit match or cigarette as this might cause the tick to regurgitate infectious microorganisms into you. Save tick in a plastic bag or vial with a moistened cotton ball for identification and possible testing. After removing the tick, call your doctor promptly and consider requesting immediate antibiotic treatment. If the tick is infected, early diagnosis and appropriate treatment is key to recovery. Delay will allow the infection to disseminate in the body where treatment is often less effective.

Consider keeping outdoor clothes in the garage or shed as ticks can migrate from clothing brought indoors and invade the home. You can also wash and dry your clothes immediately. Some people put the clothes in a trash bag then spray with permethrin and tie up the bag to kill the ticks before washing. Washing alone will not kill ticks, but a 30- minute hot cycle in a dryer will.
