We had a grey rat AKA chicken snake that lived in our crawl space. We always wondered why it stayed under the house. Everytime sun would be beating down and you came walking around the side of our house it would about make you crap yourself laying out sunning
Well my in law comes over one day and sees it and kills it. Well low and behold may be coincidental but we started seeing more and more mice in the house. Snakes like to be left alone but if they are around they are around for a reason. Unless its venomous its usually best to leave it alone. More people are bit trying to kill the snake then if they just let it be.
