The ABCs Of Tick Season In Wisconsin
As weather gets warmer and the outdoors beckons, people across Wisconsin are spending more time with the activities they wait for all winter long, including picnicking, hiking, camping, boating, fishing and more. While thoughts might be turning to filling the cooler with cold beverages and packing enough charcoal for the grill, there's another aspect to the season that demands attention: tiny ticks and their potential to cause big problems this time of the year.
Wisconsin is home to only a few common tick species, but some pose significant medical concerns to both humans and pets. However, following the ABCs of tick prevention can help ensure that outdoor activities remain fun and safe for family and friends.
- Avoid: Given their small size, ticks have limited mobility. To find hosts, ticks often hang out on plants — such as tall, weedy grasses along the edges of trails and in wooded areas with dense vegetation — and they wait for a mammal to pass by. Steering clear of these areas can help reduce the chances of encountering ticks in the first place.
- Be aware: Become familiar with common ticks and symptoms of tick-borne illnesses to know what to look for. Anybody bitten by a tick should get it properly identified and consult their health care provider about any potential medical concerns.
- Clothing: Long-sleeved clothes provide a physical barrier to help prevent ticks from getting to skin. Wearing lighter-colored clothing such as khakis can also make it easier to spot darker-colored ticks. Tucking pants into socks can serve as an additional protection to make it harder for ticks to bite.
- DEET and other repellents: A number of Environmental Protection Agency-approved repellents (such as DEET) can help keep ticks at bay when properly used. Always consult the product label for important usage instructions, such as application to skin versus clothing and how often to reapply. As another consideration, clothing can be treated with repellent products containing permethrin. These products designed for clothing treatments are often sold at outdoor and camping stores and can provide long-term protection from ticks when properly used. Some outdoor clothing brands even use fabrics impregnated with permethrin to provide protection for extended periods of time, even through repeated washings.
- Examine: Tick checks can be an important precaution for both people and pets. To effectively transmit the bacteria that cause Lyme disease, deer ticks have to be attached and feeding for extended periods of time, usually at least 24 hours. This time requirement for infection means that daily checks can help find and remove ticks before they've had a chance to transmit the bacteria. If a tick is found biting a person or pet, the best removal method is to use tweezers to grab near the tick's mouth parts and use a slow steady pull to remove it.
- Family pets: Don’t forget about four-legged friends — pets that spend time outdoors can also be affected by tick-borne diseases. Veterinarians should be consulted to select appropriate preventative tick (and flea) products. Topical repellent sprays are also available for those times people take their pets hiking in prime tick habitat. Pay special attention when selecting products for pets, as there are important differences between products available for dogs and cats. Always check with the veterinarian with any questions. For longer term prevention, Lyme disease vaccines for dogs are also available through veterinarians.
