I think yes it is, make sure you don't bring the mold to your new house. Anyway some tips in removing mold
Repair any leaks. Moisture breeds mold. If you have a leaking pipe, it's providing a breeding ground for the mold and must be repaired before you can begin to cure your mold problem.
Dehumidify the room. Place a dehumidifier in rooms that contain 55 percent humidity or more.
Protect yourself. Wear plastic gloves and a medical-grade mask to protect your lungs.
Seal off the room. Block doors and windows before you begin cleaning a room. Use plastic sheeting and painter's tape to seal duct work and other openings, too. This prevents the transfer of mold into other rooms. Only clean one room at a time, making sure to seal off subsequent rooms, as well.
Use an exhaust fan. This helps pull the air out of the room.
Use an air purifier while working. This helps protect you from inhaling too many of the particles.
Dust the rooms. Mold spores attach to dust and other airborne particles and use them to travel around.
