House sitting for a month in a big infested house?

Okay, honestly need some advice. I am staying at this house for a month. It is a nice house and when I did my meet and greet it looked fine just an older home. However I have found many house centipedes and if you don't know what that is I recommend googling because they are terrifying. I let that pass the first few times because they were all downstairs. A night ago things took a turn. I had put on ,my clothes and a few hours later I had the take them off something inside of them was itching me so bad. It was a beetle looking thing deep in my bra that was biting me. I then was laying down abut to sleep and felt something crawling. After looking it was a tick! A lone star tick that was pretty big. This last night I found another tick crawling up the side of the bed - this one was a deer tick. After a night of terrified sleep I woke up to a centipede crawling on the wall in the room. I have 18 days left and i just don't know if I can do it. Any advice? The family is out of country and I just don't really know. I am at the point of checking my clothes and body for bugs/ticks every morning and I don't think that that is fair to me.
