What kind of bug is this? When I went to bed at night, I found a few bugs in my bed. I have that itchy red spot on my body recently. Please take a look at it for me.

Wood flea, you have to clean the whole room, and the bed board should be moved out to bask in the sun. Then, use insecticidal pesticides to scrub the gaps in the bedplate and eliminate the eggs. Spray mosquito killing water in the room, and don't let go of the corner after closing the door for an hour or two, otherwise there will still be eggs if you don't kill them. I hope to adopt.
