Last week we've found two small brown bugs on our couch and yesterday another one. When we tried to take a closer look at the last one, he flew/jumped away. They are quite fast, but fairly easy to catch. I've searched on the internet, but can't find out what they are. They are small, brown, a bit shiny, they can fly a little and it looks like they have feelers/antennas. I am very worried that they might be small cockroaches, but hoping that they are biscuit bugs. Can anyone help me, tell me what they are and tell me if I should do anything to get rid of them?
