Preventing Tickborne Disease


There is no doubt ticks are worse than ever this year. Add to that is the revelation of another tickborne disease right here in our own back yard. For the next couple weeks we’re going to provide some information on how help prevent contacting a tickborne disease. First off:

Be aware of ticks.

  • Blacklegged ticks (deer ticks) are found in wooded or brushy areas while American dog ticks (wood ticks) are found in grassy, more open habitat and woods.
    • American dog ticks are found throughout Minnesota while blacklegged ticks have been found throughout most of the wooded parts of the state.
  • You should know whether the areas where you live, work, or play have blacklegged ticks. Here is a map that shows counties of highest tickborne disease risk in Minnesota.

While ticks may be active whenever it is warm outside (i.e., above freezing with little to no snow cover), be aware of when ticks are most active here in Minnesota so you can be extra diligent during these months:

  • Blacklegged tick adults are most active in the spring and fall
  • Blacklegged tick nymphs (immature ticks) are most active from mid-May through mid-July
  • American dog tick adults are most active in the spring and early summer
  • More information tick borne diseases can be found here.
