You worried about it going on for years and them not solving it. Bedbugs bite multiple times near the same area, one can wake up with 30 sores in a small spot. They itch worse than a mosquito bite. I don't think they can last more than a few months before seeking help.
If you get something...
It truly does cost a ton of money. Not to mention replacing mattresses, clothes, etc.
I did not know that a simple $10 bomb or turning the household heat up for a few hours would work. We were told heat would work for clothing, but that it had to be above something like 125*F for a few hours...
To see if they're bedbugs, look at the bed. You will see red, star shaped stains where they've spit blood. gross, I know, sorry. They usually bite near elbows and knees. Feet. Extremities.
They come from the wall. Climb up bed legs. You can see them with your eye, they're small, maybe...
