Is Peppermint Oil Safe To Use Around The House?

Peppermint oil can be dangerous if eaten. Keep peppermint oil away from children and pets.

Cats may be especially sensitive to peppermint. Ultimate Cat explains that although peppermint is in the same family as catnip, it can be dangerous when used around cats. Don’t place cotton balls soaked with peppermint oil in an area your cat can access. When spraying peppermint oil, make sure your cat does not ingest or roll around in the residue.

If you’re concerned about the safety of peppermint oil around children, consider using fresh leaves from a peppermint plant. Although it won’t be as effective as using 100% pure peppermint oil, you’ll still spread the scent in areas where spiders could hang out.

Crush a few peppermint leaves. Rub them in the areas where you typically find spiders. You can also rub them around cracks or leave them around door and window openings.

You can also make your own peppermint oil infusion. A homemade infusion contains less menthol than the 100% pure essential oil. This can help you rest easy when using it around cats or young children.

To make a peppermint oil infusion:

  • Pack a small jar full of peppermint leaves.
  • Crush them in the jar using a wooden spoon.
  • Fill the jar with olive oil. It should cover all of the leaves.
  • Let the leaves soak in the oil. This will take 2 days in the warm sun or 1 month in cool weather.
  • Shake the jar every 12 hours while it’s steeping.
  • Strain the leaves from the oil using a fine mesh strainer.
  • Keep the oil in a covered container in a dry, dark place for 3 to 6 months.

Other Tips For Keeping Spiders Away

Peppermint oil can repel spiders trying to enter your home, but it is only one tool. If you already have an infestation, you’ll need to kill the existing spiders. One of the best methods is to simply squash a spider.

To prevent future infestations, in addition to using peppermint oil, keep the area around your home neat. Don’t leave piles of material like leaves, sticks or firewood near doors or windows. Trim any vegetation that makes contact with the house.

If you’re bringing firewood, plants or other outdoor items inside, check them for spiders first.

Caulk cracks from the outside. Even the tiniest crack around a window can give spiders access to the warmth of your home.

Use a pressure washer to clean your home’s exterior regularly. Spiders can hide under siding, in corners and in gutters. Pressure washing will kill the spiders and get rid of their egg sacs.

Keep clutter to a minimum in storage areas. Dark spaces not frequented by humans or pets make ideal places for a spider web. Clean out your closets frequently, vacuuming in all the hard-to-reach places and moving things around.

Peppermint oil is not a magical cure for keeping spiders away. If you have a problem with spiders in your home, you will need to take extra measures to kill them. Using glue traps and keeping your house free of cobwebs and clutter can help.

Other essential oils that could help get rid of spiders include: lavender oil, neem oil, coconut oil, tea tree oil, eucalyptus oil, citronella oil and cinnamon oil.

Once you’ve taken preventative measures to discourage spiders from making their home in yours, use peppermint oil regularly to prevent them from returning.
