[VTCARR]

Have recently been biten several times during the night. One morning I woke to nfind something crawling on me it was black looks just like a grain of pepper. I reserched bedbugs... I checked everywhere on my mattress where they should be by internet discriptions nothing so I vaccumed my bed anyway clean entire room sealed all open cracks and bought mattress covers and zipped up mattress.. so I awoke this moring and there were still a few and I'm sure there are mice and there is a couple of birds nests in the celing are these bugs related?
