Lenawee County Health Department Mosquito and Tick Surveillance Program Underway

As in years past, the Lenawee County Health Department (LCHD) is participating in a Vector-Borne Disease Surveillance and Prevention Program in coordination with the Michigan Department of Health and Human Services (MDHHS). LCHD will be providing mosquito and tick monitoring data to MDHHS as well as using the surveillance data to notify the public of risks related to emerging vector-borne diseases.  


The surveillance program will be geared toward identifying populations of potentially invasive Aedes species mosquitos capable of transmitting the Zika virus and identifying populations of Ixodes scapularis, the black-legged tick (deer tick) capable of transmitting Lyme disease or other diseases. 


All residents can take simple, everyday precautions to protect themselves against vector-borne illnesses that can be transmitted through mosquito and tick bites by doing the following: 


  • Use an EPA-approved insect repellent: When outdoors, use insect repellent containing DEET, picaridin, IR3535, or oil of lemon eucalyptus on exposed skin and/or clothing. Always follow the directions on the package.

  • Wear protective clothing: Wear long sleeves and pants when weather permits.

  • Keep mosquitoes from laying eggs near you: Mosquitoes can lay eggs even in small amounts of standing water. Get rid of mosquito breeding sites by emptying standing water from flower pots, bird baths, kid’s toys/pools, and tires. 

  • Landscape for tick prevention: Keep the grass mowed and remove leaf litter, brush, and weeds at the edge of the lawn. 

  • Consider pesticide application: Pesticides can be applied as targeted treatments to reduce mosquito and tick populations. 

  • Perform regular tick checks: Ticks can attach to any part of the human body, but prefer body creases and areas with hair such as the groin, armpit, ankle, and scalp. Be sure to check yourself, your kids, and pets for ticks after spending time outdoors. 


Submit a tick or “tick pic” to the Michigan Department of Health and Human Services to have an expert help identify what kinds of ticks you find or download “The Tick App” to show you how to avoid ticks and tick-borne diseases.
