Keep your garbage up high on a counter where the fuzzies cannot reach it or use a locking lid.
Don't do laundry when the fuzzies are out, and if you have free-roamers, put them in another room before you do the laundry. Triple check the machines before turning them on. Shake our your laundry thoroughly before putting it in the washer. Same goes for dishwashers. We don't use ours, but if you do, always check it after you empty it and then lock it until you use it again. Check it before you use it again anyway to be sure no one crawled in there.
Consider blocking off the spaces between the floorboards and the cabinets in your kitchen and bathroom. Fuzzies like to crawl in there and they can get stuck, go through holes that may be in the walls, or get into something under there that they shouldn't.
Be careful how your furniture is placed along side of the walls. Be sure there is either enough space for the fuzies to get by, or, NO WAY POSSIBLE for them to squeeze between the item and the wall. Recyliners are generally dangerous when you have ferrets.
If you have a hole in your comforter, be sure the fuzzies have not crawled into it if you plan to wash it. Stitch it up so they do not get trapped in there.
Look in your refrigerator before you close it.
Never leave anything small enough for a fuzzy to eat on your floor or within fuzzy reach. You'd be surprised what they might eat and that could cause a blockage.
Don't keep plants anywhere that a fuzzy could reach them if you want to keep your plants alive. Fuzzies will dig them up!
If you have low cabinets with drawers on the top, keep in mind that the fuzzies may go into the cabinet and up into the drawer through the back of the cabinet. They might then push the drawer open and get on your counter. They might then push everything off your counter....so....we have taken everything out of the lower cabinets and put blankets in the drawers for the fuzzies to sleep on. We nailed the drawers shut, but keep the nails loose enough for us to turn so we can open the drawers to get the fuzzies when they are sleeping in there. Velcro works on some cabinets and drawers and also on wardrobes or armoires.
When you throw away toilet-paper tubes, remember to rip them so the fuzzies can't get their heads stuck in them should they get ahold of them.
Stockings (panty-hose) can also be a hazard to fuzzies. They like to crawl in them and can get stuck in the feet.
Be careful with plastic bags and similar items. Always be sure to rip the bottom so there is more than one opening just in case.
Always look down. Especially going down stairs. Fuzzies love to get right under our feet. Looking down shouldn't be a problem because we all get in the habit of looking down as to not step in "accidental" poop mishpas anyway, right? :)
Be wary of open windows - make sure your screens are TIGHT.
When you go out your door, look down. Be sure they aren't following you and that you are not closing the door on them. Same with closet doors.
Be careful of placing chairs close to tables, counters, ect., that you don't want the fuzzies to jump on, or to try jumping on and miss. Be aware of placement of wires and your computer keboard :)
Keep toilet lids down at all times.
Be sure your screen doors are locked and you have no loose screens in your windows.
Get rid of any recliners in the house. They just are too dangerous and risky to have with ferrets in the house.
It is always good to block any spaces around your stove/oven area so they cannot get under or behind it. If they have access to the stove drawer, I'd block that too to prevent them from going behind the drawer, and under the stove.
It is a good idea to block off your refridgerator from the sides and front so the ferrets cannot get under it or behind it.
