Tickborne Disease
Rates of tickborne illnesses have steadily increased in the county over time. The Maryland Department of Health (MDH) maintains a tickborne disease dashboard that summarizes tick activity in the state.
Tickborne Disease Prevention
- Look for ticks in late spring through early fall, when they are most active.
- Limit direct contact with ticks by avoiding wooded and brushy areas with high grass and leaf litter. Also, walk in the center of trails.
- Wear long pants and long sleeves to help keep ticks off your body.
- Tuck shirts into pants, and pants into socks, to keep ticks on the outside of clothing.
- Wear light colored clothing to help spot ticks more easily.
- Use Environmental Protection Agency (EPA) registered insect repellents containing
- DEET;
- picaridin;
- IR3535
- Oil of Lemon Eucalyptus (OLE)
- Paraomenthane-diol (PMD)
- 2-undecanone
- Use repellent on exposed skin for protection that lasts several hours. Always follow product instructions.
- Parents should apply repellent to their children, avoiding hands, eyes, and mouth.
- Clothing may be pre-treated by using products that contain permethrin.
- Treat clothing and gear, such as boots, pants, socks and tents with products containing 0.5% permethrin, which remains protective through several washings.
- Alternatively, clothing pre-treated with permethrin may be purchased.
- To ensure elimination of ticks from clothing:
- Wash clothing in hot water.
- Cold and medium temperature water will not kill ticks effectively.
- If it is not possible to wash clothes in hot water then tumble dry on low heat for 90 minutes or high heat for 60 minutes.
- For dry clothing, tumble dry clothes in a dryer on high heat for 10 minutes to kill ticks.
- If the clothes are damp, additional drying time may be needed. The clothes should be warm and completely dry.
Removing Ticks
Use fine-tipped tweezers to grasp the tick as close to the skin’s surface as possible.
Pull upward with steady, even pressure. Don’t twist or jerk the tick; this can cause the mouth- parts to break off and remain in the skin. If this happens, remove the mouth-parts with tweezers. If you are unable to remove the mouth easily with clean tweezers, leave it alone and let the skin heal.
After removing the tick, thoroughly clean the bite area and your hands with rubbing alcohol, an iodine scrub, or soap and water.
Dispose of a live tick by submersing it in alcohol, placing it in a sealed bag/container, wrapping it tightly in tape, or flushing it down the toilet. Never crush a tick with your fingers.If you develop a rash or fever within several weeks of removing a tick, see your health care provider.
Tell the health care provider about your recent tick bite, when the bite occurred, and where you most likely acquired the tick.
Tick Identification and Testing
Tick Identification is available through the Johns Hopkins Lyme and Tickborne Diseases Research and Education Institute.
Disease testing is offered through the Tick Research Lab of Pennsylvania in East Stroudsburg, PA. Please note that non-Pennsylvania residents will have to pay a fee for tick processing.
If you are in the military, MilTICK is a free tick testing and identification service available to Department of War (DoW) personnel and their dependents.
