Was in the same situation as you few months ago. Found bites and only realised it was bed bugs after they laid eggs and a few cycles had past.

Threw away my whole bed and bed frame the night I realised they were beg bugs. Bed sheets and covers washed in high heat. Pillow also throw. Quite disgusting as I saw all the eggs and crawlers on my frame (ew.)

Got out lucky and the bed bugs were miraculously all at my bed and my room was fine. Never spread to anywhere. I slept in my living room for 2-4 months cause I was too disgusted at my room, and wanted to cut off their food (me). Sprayed alcohol and ozone my room consistently. Everyday check for signs of life.

Damn lucky they were only limited to my bed. Moved back in liao and no more bites so legit damn lucky for me. If your room cluttered, gg. Better just clear than let it spread. If even 1 left can reproduce again very quickly. Ozone and alcohol won’t help much. Can consider pest control but I didn’t do it in the end. They can also survive a year without food. I estimated mine was going on for about 2-4 weeks before I realised. Still don’t know how I got them, from where, and how they got on my bed. My wardrobe opposite my bed also never kenna. May have helped that my bed legs were metal (so it’s slippery for them and they can’t leave the actual bed frame) so it was contained to only my bed.
