I’m looking forward to way less to no ticks (and other bugs) this spring from the intense cold. Those things give me welts that last for months.
It should kill the ticks, but they'll be back, hopefully in lesser numbers. Here's an article on that: https://adk.org/ticks-in-winter-ostfeld/#:~:text=Many%20have%20inquired%20if%20cold,come%20out%20the%20following%20spring.
I saw a study that said that in order for the cold to kill the bugs it would have to be below freezing for over a month straight. :-\
