There are certain scents homeowners and business owners can use to repel spiders. Spiders hate the smell of citrus fruits, peppermint oil and vinegar. Using these scents around a house or business is an effective and easy way to keep spiders from coming inside.
One home remedy some people use to keep their home spider free is cleaning with a vinegar infused with citrus. To do this leave orange peels in a cup of vinegar over night. The next morning mix the vinegar with water in a spray bottle. Simply use it as a cleaning agent or spray it around areas around the building spiders are likely to enter.
