From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
For Bed Bugs in Bedsteads.
One ounce mercury, two ounces hog's lard rendered down, then take a drachm of bruised wolfswort, one drachm juniper-berry oil, make into a salve and apply the same to the cracks and screw-holes of the bedsteads. A good remedy. Probatum.
The grimoire Egyptian Secrets of Albertus Magnus lists this spell.
