Bringing plants in and out is very risky! Also just your shoes or clothes can bring them into your controlled area. Many people don’t like clones for this reason. Here’s a great way to cleanse your plants before bringing them in. Maybe not for your situation of just bringing them in at night though.

And there’s many types of ticks out there.
Deer ticks, dog ticks, lone star ticks, winter ticks…
Just depends on the area of the world you live in. Not all carry the same diseases.
Lyme disease is named after a town called old Lyme, which is near plumb island, a bioresearch facility that a former Nazi Dr, Erik Traube, if memory serves, researched transmission of diseases through ticks. It’s not well documented, but kind of a crazy rabbit hole.
