Snakes in the laundry room!

This is what was found on my washing machine today! After opening up our kitchen floor for some renovations this past April for a few days...we have had creepy crawlies, flying thingies, mice and now SNAKES!! My daughter went to grab something from the top of the washer and this is what she found. I googled it and I think it is a baby rat snake...probably here to rid me of my mice problem...so what do I get to rid me of my snake problem?
