To cast a spell to protect your home, during the waxing Moon and during the thrid hour after sunset, pick a few stems of any combination of the following hebrs: dill, fennel, marjoram, mint, mustard, mullein, rosemary, rue, (and if you are not allergic) white heather, woodruff, and yarrow.
Tie small bundles of these herbs together with red thread and place on an altar (if you do not have one, a table will do) Touch the bundles with a ritual knife (or a kitchen knife will work) saying:
I conjure thee protective herbs, on this day and in this hour of Mars, to be a protection and safegaurd agianst all adversity and evil. Protect well this house and all who dwell within. As I will so mote it be!
Hang one bundle in each room of your home.
