For getting rid of bugs: mint. Ants, roaches, termites, and nearly any creature that crawls close to the ground hates mint, and this includes mice. Mint is sacred to Mercury, so it's entirely possible that adding some propitiations to Mercury could help it repel bugs (and mice) from your space. You might try putting some essential oil of peppermint in an infuser or mixing it with water and a dash of rubbing alcohol in a plant mister and spritzing it around the apartment. When my house had mice, I used to sprinkle the essential oil all over the basement and put it on cotton balls in the oven drawer.
