The population boom of deer ticks around lower Michigan cities has become a pressing public health concern. As animal populations grow and outdoor activities increase, encounters with ticks are on the rise. Medical entomologists report that black-legged ticks, commonly known as deer ticks, are now being found in areas previously considered low-risk, with their populations expanding across southern Michigan and along the Lake Michigan shoreline.
The Michigan Department of Health and Human Services has indicated that 81 out of 83 counties now face a risk of Lyme disease, which is primarily transmitted by deer ticks. Deer ticks are notorious for carrying Lyme disease, which can lead to severe health complications if not treated promptly. Symptoms may not appear until days or weeks after a bite, making early detection crucial.
The immature stage of the deer tick is particularly dangerous due to its small size, often likened to a poppy seed. Michigan residents are urged to take preventive measures such as:
• Having sprays done for ticks throughout the growing season – ticks can be active anytime the weather is above 32 degrees Fahrenheit.
• Wearing protective clothing – ticks can be spotted best on light-colored clothing.
• Using EPA-registered repellents when engaging in outdoor activities.
• Avoid brushy areas and areas with tall grass when venturing outdoors.
• Conducting thorough tick checks after outdoor activities – don’t forget to check your pets, too.
It is vital for Michigan residents to stay informed and vigilant in protecting themselves, their families and their pets from these harmful pests. If you want to find out more about treating your yard for ticks, contact Owen Tree & Lawn Care today.
