We have been trying to sell our house for a while now, It is priced way low and in an excellent neighborhood. People tend to be put off by the critters. I am going to buy tubs to hide everyone in the closet till moving time. How do you keep the tubs locked??? Also how do you know when you have enough ventilation holes??? The closet stays about 80 degrees at all times. I don't have time to get heat for tubs before open house this week.
