A longer and wilder lawn can be better for the ecosystem, but it raises questions about the health risks of a potentially larger tick population around your home. “When we’re talking about your risk of exposure, we are talking about two things,” Dr. Keesing told the New York Times
. “At work are both the entomological risk — how many ticks there are in the habitat — and also how much time you’re spending in that habitat.” Dr. Keesing discusses the results of her five-year Tick Project study for the Cary Institute of Ecosystem Studies.
