I picked something up a washer machine off Craigslist and 2 days later I see a cockroach running underneath it. I am freaked the fuck out I'm in like a state of panic I have never seen one before this. It's like a fucking nightmare. What can I do I don't want the exterminater man wondering around my house. I only saw the one but I'm afraid that they have gotten into my house now from this thing. What do I do?
