If you're really worried recite this prayer for a while and tomorrow learn the LBRP (Lesser banishing ritual of the pentagram) and do that for a while.
"Hear me, and make all Spirits subject unto Me; so that every Spirit of the Firmament and of the Ether: upon the Earth and under the Earth, on dry land and in the water; of Whirling Air, and of rushing Fire, and every Spell and Scourge of God may be obedient unto Me."
