Same here in Estonia. Nights are currently around 0 degrees C and days about 12C, will get a bit warmer shortly.
Why are ticks getting more active right now in your area? Prime time here for them is summer. Right now they get less and less active because they don't enjoy cold. If you ask from me, I would love for them to die out. They are no use to anytone. Even animals don't really eat them.
Ah I had a classmate from Estonia! Beautiful place for sure, and she was also a very beautiful girl :D
The ticks are more active right now to get the last feedings in before winter and they will die off. One of the things I like so much about winter here is it gets cold enough that those fuckers die off.
