Ugh. Can you smell them? TRUE STORY TIME: My late husband and I had been on vacation for several days, probably a week or more. We came back home and my husband said "I smell mud in this house." I couldn't smell anything. I went to bed later, after walking past the front door about a million times. My husband eventually followed me to bed, but got up around 2 am because he said "I smell mud in this house." He walked toward the front door, where the smell had always been strongest, and saw a COTTONMOUTH trying to get out the door! He grabbed some pincher thingies that my dad used to have, and he pinched the head of the snake until it was dead and then threw it in the yard and then came back to bed and said, "There was a snake in the house but I killed it and threw its body in the yard." Talk about going from zero to about 100 in about five seconds! I went from sound asleep to wide awake in no time but everything was taken care of, apparently.
