Boy insect photography

Is it about two-thirds of the length of the little finger, with many feet and dark brown? I had it before my dormitory! (PS: I'm from the boys' dormitory) but I don't know if I've been bitten ~ are there many things under the bed? Like books? Clothes? A quilt? Or is it because the bedplate and bedding are too wet to find bugs? I suggest you go to the supermarket to buy black charcoal-it can absorb moisture, and you can also sell insect pills ~ put them under the bed, but don't put too many insect pills, it tastes terrible! And turn on the fan, and turn on the air conditioner if possible! Fumigating wormwood! After my mother "disinfected" our dormitory last April, it seems that bugs never appeared again, but don't pile too many things or eat snacks on the bed afterwards!

Personal experience, I hope I can help you ~!
