After the Groundhog Day celebrations and prognostications have past, mid-February is about the time news reporters start asking tick experts \u201cHow bad are ticks going to be this year?<\/em>\u201d And after the \u201cwhat winter?\u201d most of us have experienced across the eastern United States so far in 2023, speculation will likely be even more intense, with the assumption being that since [lack of] winter didn\u2019t kill ticks off, ticks are likely to be bad this upcoming spring and summer. Right?<\/p>\n\n\n\n

From Georgia to New England, most locations experienced one of the five warmest Januarys EVER. Warmest-ever daily records have been set. Boston\u2019s winter has felt like Washington DC, and Washington like Atlanta. Accuweather reported that every day in January was above average temperatures in New York. Except for an 18 hr cold snap, February so far, also has been balmy. And yes, ticks ARE out and active; more specifically, adult blacklegged ticks, carriers of the Lyme disease germ are biting people and pets.<\/p>\n\n\n\n

So, what do tick experts say about it? Is this weird, warm winter heading us all for a springtime and summer tickapocalypse? \u201cNo one can say right now,\u201d agreed a recent consensus of seasoned tick scientists affiliated with the New England Center of Excellence for Vector-borne Disease (NEWVEC)<\/a>. Ticks have been around a long time and have figured out how to effectively survive winter. Adult stage blacklegged ticks, left over from their Fall active season, become active even in winter<\/a> whenever temperatures are warm enough for them to move the muscles in their legs\u2014usually above freezing. They\u2019ve been active this winter quite a bit and their springtime activity usually peaks in April but could come a little earlier this year.<\/p>\n\n\n\n

Then, there\u2019s the poppyseed-sized nymphs<\/a>, which typically start their springtime blood-quest in May, and one 10-year study1<\/sup> showed how they start off at about the same abundance level each year, with the severity of their onslaught, and risk for Lyme disease, depending on weather patterns in early June, and not winter weather at all.<\/p>\n\n\n\n

Scientists found it was the number and severity of drying conditions\u2014they called them Tick Averse Moisture Events (TAMEs)\u2014that was predictive of whether it would be a bad year for these ticks or not.1<\/sup> TAMEs were any day when sub-82% relative humidity in the shady, leaf-covered habitat typical for this tick stage lasted longer than 8 hours. That\u2019s when nymph ticks started to dry out–the proper term is desiccate\u2014and die. Over the 10 year study, when June had more than 4 or 5 such TAMEs, then tick and disease risk was lower, usually about 50% lower.<\/p>\n\n\n\n

The bottom line, ticks don\u2019t die in winter, and the severity or mildness of winter weather doesn\u2019t appear to predict spring and summer tick risk, but for blacklegged ticks, desiccating conditions in June definitely does. Still, it\u2019s never too late (or early) to be ready for ticks.
