Whoa! If you believe tick season is over - you are mistaken! Even in somewhat cooler places like Minnesota and Wisconsin, ticks are prevalent through October (unless there are multiple hard frosts), and for sure in Illinois, most of the midwest, lower southwest and for sure the norrtheast. Truth is ticks are found in all 50 states.
People go camping in those rural places, and then bring dogs back to big cities like New York and Chicago, so there are even ticks in Central and Lincoln Parks! Certainly lots to live off there, from squirrels to city rats (ugh). With ticks arrives tick disease in dogs, and that's what my conversation with Dr. Ruth MacPete is all about.
