Place a few horse chestnuts in each corner of the house and in any area of the house where you frequently run across spiders.  Chestnuts, walnuts, and the fruit of the Osage orange tree are thought to have the same effect. Little is known about why this treatment repels spiders, and there is no scientific evidence or explanation backing the solution. Some speculate that horse chestnuts have some form of noxious chemical that repels spiders based on scent. To this end, consider poking holes in the chestnut or splitting it in half to release the odor. Fill a standard spray bottle with water and mix in 15 to 20 drops of peppermint oil. Spray down all the cracks and corners of your house.  The idea is that spiders cannot tolerate the smell of peppermint oil and will run away in the opposite direction when they detect it. As a result, it is most effective when applied to possible entrances to the home. For a more potent effect, you can dab undiluted peppermint oil onto a cotton ball and stuff the cotton ball into cracks or other possible hiding places. Try eucalyptus oil or tea tree oil if you have a thing against peppermint. They reportedly have the same effect as peppermint oil and can be used in the same way. Scatter a fine layer of this powder around cracks, corners, windows, and basements. Spread it anywhere and everywhere you expect a spider to be.  This powder is made from naturally-formed fossils of a water creature known as the diatom. It is safe for both people and pets. When a spider crosses over the diatomaceous earth, its exterior gets cut up, causing bodily fluids to leak out. The spider eventually dries out and dies as a result. You can also protect your home and prevent spiders from crawling in by spreading diatomaceous earth around the perimeter of your house. Mix equal parts white vinegar and water in a spray bottle. Apply it to any area in which spiders gather and spray it directly on any spider you see.  Vinegar contains acetic acid, which is thought to burn and kill spiders upon contact. You can also place small dishes of vinegar in dark corners to ward away spiders. The odor alone may be enough to repel them.
