Snake on the loose

I'm trying to get the windows and doors on the back of the house painted during this last heat wave. Hubby took the doors off so I could work on them on sawhorses. This is the door to the craw space under the house. Looks like there may be a large black snake living under there. Fine by me, I like snakes and they eat mice. Maybe why I never see one! There may actually be a few snakes on the loose...people fear things that really are no threat to them sometimes. It does not work well for the snake most of the time...unfortunately
