Bed bugs are a likely suspect for bites obtained in the bedroom and you really don't want to have them. I did help someone get rid of them once. I only advised and he did all the work. I never saw his appt. He didn't even own a vacuum cleaner at the time. That pic does look like larvae of some kind and not the bed bug variety.
Since you have the rash on your hands it may just be contact dermititus. An alergic reaction to something you touched.
They can easily be brought home if you have been traveling and staying in hotels.
The one thing you really didn't provide is "how big" in a real size or in comparison with another object that we know like a dime or even a ruler. With that I could have measured the bug from the photo.
I have been having my share of extermination problems in the past couple of years.
Last year was bees. Possibly carpenter bees because they were really aggressive. Patching holes in trees is interesting.
This year some form of bug that likes rice. A hot/cold pack was given to us which had rice inside. Well, there were bugs inside too. They liked wool and rice. The process wasn't fun, but it was a lot easier than the bed bug process which ultimately involves sealing the matress for a few weeks until they die.
This year I am also dealing with carpenter ants and slugs, although not inside. They are messing with an oak and an apple tree.
Ants have also been a problem this year and so have mosquitoes.
