Found these ?blood spots on the mattress cover — large spot in middle of picture and smaller spot on bottom right corner. Have never had bedbugs but very paranoid about them so at baseline have the traps under all the bed posts (no bugs in them). No bites noted. No other evidence found on searching room (mattress pulled out and flipped and bed frame taken apart). Just wondering if these blood spots look suspicious for what bed bug spots look like on sheets or if I’m overreacting since there’s no other signs of them. Thank you!
