very much relies on where you live. For instance if you live near the coast in southern parts of Norway and go for a hike you should allways check for ticks afterwards. I usually just take a shower as soon as I get back home to make sure i get them off before they bite.

It is not uncommon to find multiple ticks on your clothes if you have been walking in tall grass. But they usually take quite a while before they find a spot to bite. So if you take some precautions it is not a big problem.
