Especially 1 for me is very effective, but it is important to not let the vamp event trigger in a save. You can also try the private lot thing mentioned above but I have not tried it myself so I can't speak for how well it works, the above methods I mentioned above have kept my non vamp saves basically vamp free. If your sim likes gardening I also will plant garlic going up to the steps of the house since the garlic plants also ward off vamps. I usually put the ceiling hanging braides because they aren't visible in live mode as much. You may still have to check the townies bin every once in a while and delete some that are generated, but break-ins should be reduced/non existantģ. When you start the save, before the Vlad into sets off, delete all the vampire households in FH.
