I've been in to one to many homes with pest control issues. If I see some critters crawling around, it makes me not even want to sit down on their couch. Especially if those critters are cockroaches. I would rather burn the house down and never go back. Luckily getting a pest control company to take care of it isn't too hard. If only it was as easy to find a nice way to tell your friends they need to hire someone.
