Although many spiders produce venom in order to capture their prey, most are not harmful to humans; in fact, they do not like humans and tend to stay away from them. The first thing to decide is, do you want to repel the spider or kill it. In this article, we are going to try to concentrate on the specific plants that repel spiders.
Apart from being ugly, having eight legs, and covering your house in cobwebs, your everyday spider doesn’t do much except eat flies and bugs. In China, they are used on mass to protect rice fields by feeding on the insects. The same in North and South America. So the best sort of insecticide would be the spider. Obviously, some of them are poisonous, Black Widow, Red Widow, Brown Recluse, Funnell Web, to name a few. Their bites sometimes only kill localized tissue and sometimes more severe allergic reactions. So if you should come across these beauties, get professional help.
Why Spider Prevention Matters
Prevention is always better than a cure, however, it is not always that easy with spiders. Don’t expect perfection in ridding your house of spiders, they will become resistant to chemicals and often avoid them. With their long leg’s spiders can keep their bodies out of the way of sprayed insecticides, their feet do not carry the chemicals through to their bodies so it pretty much a wasted effort.
That leaves natural methods and common sense.
Common Sense Spider Repellent
Spiders like dirty, smelly places, so if you leave dirty washing all over the house you will find spiders in it, same with dust, garden rubbish, food debris, etc. So keeping the place clean will help a lot in preventing them in the first place.
Also, cobwebs, spiders use cobwebs to traverse your home as well as to catch prey, the cobwebs are not exclusive to the spider that spun them; they all use each other’s webs. Clean the webs out as this will assist in slowing them down. You can lay glue traps on boards under furniture. Fill in or spray crack (this works because the spider crawls out of the crack and it gets on their body) and use air vents that you can close. Most spiders are loners, so the usual and very effective method is to hit it with your shoe.
Although, you can use some plants to repel spiders, as well as their oils. In the next section, we will look at some of the smells that spiders dislike. Therefore, you can either make a spray, or use the plants. Keep reading for an explanation about how to make a spider repellent spray.
Plants That Repel Spiders
Spiders don’t like smells that we as humans find nice, such as; Eucalyptus, Lemongrass, Lemon Balm, Mint, Lavender, Basil, and Rosemary. They are all plants proven to have worked on spiders because of their strong smell. They also keep other insects away. Therefore, it is a two-fold benefit: Fewer spiders, and a nice smelling home!
The leaves of the eucalyptus tree are very good at keeping bugs and insects away from your house and therefore removing sources of food for the spider. You may need to plant the dwarf variety in your garden as they can grow to be quite large.
Alternatively, you may be into the art of bonsai, in which case, you could grow a bonsai eucalyptus in your home. That will give you very decorative plants that repel spiders at the same time as looking beautiful.
Although lemongrass plants may look like an ideal harboring for spiders, they are actually pretty good at warding them off. The citronella oil, and the acids present in the grass, give out a distinctive lemon smell that spiders hate.
The lemongrass plant does not do well in winter. Therefore, if you are using them to repel spiders from your garden, you will need to bring them in or store them in smaller volumes in a greenhouse. However, if you have them in your home already, they will be excellent spider repellant plants all year round.
Spearmint, catmint, and pennyroyal are all good spider repellents. A lot of people claim that peppermint is a strong deterrent to spiders and other insects. They have the added advantage of being able to be spread all over the house.
Keeping a lavender plant in areas that you seem to get loads of cobwebs will help to repel them. They do need lots of care and attention and sunlight though.
Another strongly-scented plant, also good for getting rid of flies and other bugs. It doesn’t need a lot of sunlight, so it is good for those who do not live in hot climates.
The aromatic and volatile aromas of basil, ward off spiders very well. They do not require a lot of attention but do need sunlight and regular watering.
Keeping rosemary in a pot near the areas of massive spider activity is a good idea as spiders find the smell to be absolutely disgusting.
If you haven’t noticed, anything with a strong smell is likely to repel the spiders from your home. Keeping one or more of these plants in the areas stated will help to repel spiders from your home.
Spider Repellent Plant Sprays
You have two options to create a spray from plants. You can either:
- Create oil from the plant.
- Buy essential oils.
To create essential oils you will need to buy an essential oil distiller and follow the instructions for the kit that you buy. I could go into the specifics of how to create it yourself, however, different apparatus will require different methods. Therefore, we will tell you how to make the “spider spray” from oil once you have it.
- Fill a spray bottle almost full with water.
- Add 5-10 drops of your chosen essential oil. Any of the above will work, so use the one you find the most pleasant to smell.
- Put a couple of drops of dishwashing detergent in.
- Shake to mix the oil and water.
Now all you need to do is periodically spray the liquid in all of the areas that you may find spiders. Such as around baseboards, door, and window frames.
Using these plants and sprays around the home is sure to repel almost all of the spiders that you will find in the home, so long as you position them correctly. Let us know if you have any other plants that you have found to work well, and we will feature them in the article too.
