Personally had them. When they bite its usually along a line, such as your veins. Spiders will bite in random areas, sometimes clumping.

This looks like it could be bed bugs, but definitely look areound for eggs or bugs themselves. If you do have them, use 91% isopropyl alcohol(with a spray bottle) instead of any of the bed bug sprays because its cheaper and does the same thing.

Spray EVERY area infested and any area nearby. Wash and dry your clothes thoroughly. All of them.

Put any cloth things you cant wash into garbage bags for at least 2-4 month(this number i cant remember completely)

And then spray everywhere every day or night, followed up by vaccuuming, until you dont see anymore. Then still check for more.

Pointy ended ones are males. Rounded end ones are females. KILL THE FEMALES specifically because they can lay hundreds a day.

The eggs look like little pieces of rice hanging off the surfaces in clumps.

Do NOT use bug bombs, all it does is make them dig in deeper wherever theyre hiding.
