Peppermint Oil

NM

I’ve been living in my apartment for since Feb 2022 and no sign of any rodents, bugs or anything unless I would not be home for weeks at a time and a spider would be in my tub, that’s ALL. Last month the lady next door moved out and I saw a mouse run across my floor. Instantly we got traps and caught two, we thought it was over until I saw one on my stove so we caught that one, after the 5th one I just cried so hard and realized that they’re going to keep coming so the internet suggested peppermint oil. I got the peppermint oil today but I wanted to know is it save for my 8 month old to inhale? I put a few drops down already and she has no reaction to it but I just want to make sure.
