booklice

Hi guys.(please answer i’m really concerned regarding this matter)

i’ve been suffering from booklice since one year now.. the house i was in before was infested. I moved to a new house didn’t take any furniture with me or boxes or whatever only my clothes. somehow they came with me to my new house. i did everything that needed to be done wiping walls with vinegar pest control i’ve been checking everything since a year. morning and night. however since last september ive been seeing them rarely. and of course im very careful with the humidity it’s between 29% and 50% im doing everything that needs to be done.

NOW HERES MY QUESTION…. for people who have suffered with them when you are at the edge of getting rid of them… is it normal to see one every 3-2 weeks? just one wandering. or it’s not ok?

please i’m looking for answers.
