I am totally freaking out...i was sweeping up my new hardwood floors and i saw something run behind my chair?

in my living room ...i hurried and stepped on it and i am totally freaked out that it looks like a roach??? a few weeks ago i saw june bugs covering my porch at night when i would leave the deck light on...but this definitely wasnt a june bug...i keep my house clean but i do have a window air conditioner located where i found this bug...could it have come thru my window?? my neighbors who are all within a few feet of my house have nice kept houses...all i can think of is that i brought something home from a grocery store or its an outdoor bug...i looked at pics of bugs in michigan online and it looked most similiar to an adult german cockroach...this is the first and hopefully last one i have seen,...i hate bugs of any kind and i am totally freaked ,that is why im up this late,normally i wouldve been in bed 2 hours ago but this is making me totally want to clean and disinfect from top to bottom!i was so worried i even called the guy that did my floors and he said he never saw any bugs

IF it IS a cockroach- it might be a "Sewer Roach"- huge, ugly brutes- whose hours are numberd in your house, because they don't live long away from the Sewer... They tend to be "isolated incidents"- so you might not see any more of them... (until NEXT year...). Keep an eye out for any more, and if you DO catch another one of whatever it was, call an exterminator & have the place checked out. (By the way, Sewer Roaches do NOT reproduce in peoples homes. They just freak them out ! :) )
