My wife is terrified of spiders so we needed to find a safe/natural way to reduce the number of spiders coming into our home. A while back I stumbled on a method using basic white vinegar and peppermint oil. We tried this last winter and the results were amazing. I think I only had to relocate one or two spiders the whole winter! Later I discovered the method using diatomaceous earth. When used correctly, this method is 100% effective. The downside is rather than repel the spiders unharmed, it kills the spiders.
By the way, if you are unlucky enough to get bitten by a spider, here is a great post on spider bite identification. If you are unsure of which venomous spiders live in your state, here’s a handy guide.
METHOD 1: How To Deter Spiders Naturally With Vinegar & Peppermint Oil
Here’s how we did it – get some white vinegar and some peppermint oil; mix 1/2 cup of vinegar with 1 cup of water, and then add around 20 drops of peppermint oil.
Add the mixture to a spray bottle, shake like crazy and then spray around windows, doors, air ducts and anywhere else you think spiders may be entering your home. Another thing you can do if you have lots of air vents or holes in your walls/floors is to soak some cotton balls in the mixture, and place them in the ducts and holes etc.
If you do this once a week, you’ll notice a dramatic reduction in the numbers of spiders entering your home. We tend to have a big tidy up and vacuum once a week or so, and we just sprayed when we did this, it just became part of the routine.
Amazon has a huge range of peppermint oil, some of which have free shipping.
METHOD 2: How To Kill Spiders With Diatomaceous Earth
( ***Also works for ants, cockroaches, and fleas***)
What if I told you there is a natural product that will get rid of ALL of the above? In fact, it will kill any bug with an exoskeleton, so that covers most of the other bugs we don’t like too. This product is 100% natural, non-toxic to humans and mammals, and safe to use around kids and pets, it’s also inexpensive. Want to know what it is? It’s called Diatomaceous Earth. Diatomaceous Earth (sometimes called diatomite) is the fossilized remains of hard-shelled algae (known as diatoms). It is 100% natural and looks like an off-white talc powder.
How does it work and where to use it
The way it works is simple – diatomaceous earth sticks to the bugs and absorbs the lipids from their exoskeleton which causes them to quickly die through dehydration. Most, apart from beetles, will die within 24 hours.
To get rid of all these critters from your home, simply sprinkle the DE powder in the places where they are getting into your home and hiding. Some of the best places to use it are around doorways, windows, and air ducts – and sprinkle it under all of your furniture. You can also use diatomaceous earth directly on ants‘ nests if they are too close to the house. Whether you use it indoors or out, it is vital that you keep DE dry as it becomes ineffective when it gets wet.
What to buy and where to get it
When buying diatomaceous earth, you want to make sure you buy ‘food grade’ diatomaceous earth. There are other types of diatomaceous earth such as ‘pool grade’ that can contain added ingredients which may be harmful. ‘Food grade’ diatomaceous earth is totally non-toxic to humans and mammals. In fact, it is often mixed in with grain-based food to keep it safe from bugs.
