 You are living with alien-like creatures. They breed through their skeletons. They can even taste with their feet. And now they are invading your home. Blood suckers and flesh eaters, they want your body, or the very least your skin.Welcome to 24 hours in the bug brother house.  This could be any house, any house, anywhere, a nice place on a nice street. And as the sun comes up, all is quiet. It looks like a lovely family home, but looks can be deceptive. Scretch the surface, and this is a house of horrors. We're about to spend 24 hours in a family home, and meet the ones who are really close, arlotchers. The cocroach is just the advanced guard. One of several thousand tenants who aren't the sitting kind, they crawl, riggle and bite. Many just need human company, and sometimes your flesh and blood. We're going to meet the hidden house maids.
