Great news for arachnophobes - you can reportedly prevent spiders from entering your home by using a well-known essential oil.
Goodtoknow.com claims that spiders can't stand peppermint oil and it acts like a repellent, driving them back outside.
Simply put a few drops of peppermint oil in a spray bottle with some water, and spray the mixture around your house once a week.
It's recommended that you dust and vaccum first before spraying the peppermint oil around doorframes, windows, your bath, shower, and any places where you think the creepy crawlies are getting in.
If the spiders keep coming back, use the spray every few days or add another drop of oil to the bottle.
We're definitely going to try this.
