Won’t add what others have already suggested, but maybe I can offer some reassurance.

I’ve lived here 20 years and only twice have the humans in my family had an issue- and by issue I mean finding a tic well before it was embedded. We do use OFF brand tic/mosquito spray when we know we are higher risk of encountering tics, but never for just around the yard.

We have animals so unfortunately they have had them (esp if I lose track of their preventative monthly med dose schedule). My dog ended up with a latent anaplasmosis infection but never had symptoms, and no longer tests positive for it. Key here is making sure you don’t let the dose schedule lapse, and it shouldn’t be an issue.

Welcome to NH.
