One method I've used with my older kids is that if I can't trust them to follow the rules, then I need them to stay by my side so I can keep them safe. This means sitting on a chair in the kitchen while I make lunch instead of playing with the other kids, holding on to the stroller during walks instead of walking in front with the others, not going to play until I have finished cleaning up and can go too etc. They whine and complain but I explain that it's my job to keep them safe and if I can't trust them to follow the rules (which are there to keep them safe) then they have to stay with me so I can keep them safe. Basically a complete loss of all freedoms and privileges.

I'm not sure what your house set-up is like, but one thing that I've done was gate off my entryway from the rest of the main floor. I had to get one of those long, extendable gates, but after the first week it had paid for itself at least twice. Kids couldn't come in and run on my carpet with their boots and dirty shoes. They couldn't play in my hall closet. They couldn't access the stairs or the upstairs of my house which is off limits to daycare. They couldn't dig through each others bags while I wasn't looking. They couldn't smash on the glass of the screen door. And best of all, it stopped kids from running from their parents at pick up time. When the parents arrived, I would just scoop them up and put them down on the other side of the gate. Would you be able to gate off parts of your house that they aren't supposed to go in?
