Tick season starting early this year

People also should keep alert for symptoms of tick-borne diseases.

In Minnesota, patients already are testing positive for tick-borne diseases such as Lyme disease, anaplasmosis and babesiosis -- a month or two earlier than normal for the state, said Dr. Bobbi Pritt, a microbiologist and director of the Clinical Parasitology and Virology Laboratories at the Mayo Clinic in Rochester, Minn.

Lyme disease and anaplasmosis both are caused by bacteria carried by ticks, while babesiosis is a parasite that infects red blood cells.

But there are a number of things people can do to protect themselves from ticks.

"The first thing is just tick avoidance -- staying out of areas where ticks are going to be present: tall grasses, shrubs, leaf litter," Pritt said in a Mayo Clinic news release.

"Also use insect repellant, such as DEET," Pritt added. "You can also buy clothing that has been impregnated with pyrethroids, which is another type of insect repellant, and there are certain types of insect repellants for pets."

Some other tips:

• Keep grass short in yards and don't go into overgrown areas.
• Wear long clothing to prevent ticks from accessing your skin.
• After spending time outdoors, thoroughly check yourself, your children and your pets for ticks.
• Stay on trails when you hike. If you leave the path, wear long pants tucked into your socks.
• If you find ticks, remove them immediately. Pinch the tick near its mouth and pull it out slowly in a continuous motion. Don't twist the tick because doing so may leave mouth parts embedded in the skin.

Fever, headache and muscle pain can be signs of a tick-borne illness. A hallmark of Lyme disease is a bull's-eye-patterned rash. Even if you do not recall getting a tick bite but have been working outdoors or visited other tick habitats and develop such symptoms, make sure to mention this to your doctor, Pritt said.
