what helped to teach your puppy to leave things alone

My pup’s access to the house is very restricted right now to prevent bad habits from forming.. every time a new time is added to her area I do redirect a lot but at some point you’re at your 30th “leave it” and treat scatter that you wonder when will this get better 🥹

Any tips? I mean shes 4.5 months old so very much still teething.
