I agree with the increase in tick population. Share similar background growing up. Uncles had a fruit and dairy farm in Columbia County. Grandparents bought a house and acreage. Spent every weekend and every Summer there. My Dad has the place now, so I have never not been there. Back 15 years ago, when we had 13 deer per square mile, never saw a tick. Fast forward to less than a decade ago, with a great decline in deer population, and the ticks are everywhere. Went and posted the property with my cousin, and I picked 13 off of him, and he got 6 off of me. I missed one on him, he got it off his armpit during the night.
I think the fact that the Winters are not as severe has something to do with it. While still cold, we are nor seeing deep freezing temps for several days. Those deep freeze temps, when they continue for several days, kill off the ticks that are not attached to a host to keep them warm. Otherwise, they can stay dormant on a blade of grass for weeks at a time, just lying in wait for a host to walk by.
I wish I knew another reason as to why they are so prolific. Then, maybe I could do something to prevent their existence. Until then, I will spray down with Prem, keep cuffs tight, and be alert.
