I'm assuming that you've asked her to remove these things and she's refused or simply not responded. Is she nearby that you could pack them up and take them to her? Is the issue that she needs help moving them -- if so you should offer to help. At some point after asking her to remove things and she doesn't, you can throw them away but that's really a last resort. You'd need some sort of proof that you communicated with her, requested that she remove the items and the action you intend to take by the date if she fails to respect your request.
