Yes, always use physical means first and back up with the metaphysical.
First, once your house has been set with better security, burn sage and move the sage in the air. This is called smudging and it'll cleanse the home of unwanted energy. Use it in every room of the home, focusing on pushing out lingering energies left by the robbery.
Once that is done, you can use a variety of chants or come up with your own to ask the divine to bless your home and keep it from being intruded upon. As you may this prayer, trailing a thin line of mixed ingredients along the border of your home may help.
The ingredients may include cinnamon, salt, very finely chopped garlic, ashes of ague weeds and finely chopped unroasted almonds.
You may also blend the ingredients after acquiring some blessed water, either after ritually sanctifying it or if a local priest has allowed some to be blessed and then sprinkling it lightly around the home.
