I don't know what these things are, maybe bedbugs. They're maybe about 1/4", teardrop or shield shape, and kind of dark reddish brownish. The other day I picked up a suit coat and they were running out of the pocket. I got rid of a bunch and then used ant and roach spray on it. I let it rest for a while and then took it in the bathroom. There were some left, which I picked up and put down the drain. There were also very small whitish bugs, which I figure were an earlier stage. The couch is near the litterbox because not a lot of options, and the cat goes outside sometimes, though usually not for long. Could he be bringing them in on his fur? Would dry cleaning fix the coat? What do I do about the couch? I probably can't afford another one right now. I don't like the swollen itchy skin bumps either.
