15 Plants That Will Repel (Or Kill) Spiders in Your Garden

#1 Peppermint

Peppermint is one of the best choices for keeping spiders away from your garden. If you didn’t know, spiders are very sensitive to scent, which is how they detect friends and foes. As it happens, a peppermint plant produces intense scents that can penetrate through a considerable area. This widespread scent should be an efficient motivation for spiders to stay away. In short, plants in your indoor/outdoor garden will be free from the potential damages a spider could inflict. However, it would be best to keep in mind that peppermint is an aggressive plant in many ways. So, you have to re-pot the plant if you think the growth is out of control.

#2 Lavender

You do not have to think about repelling or killing spiders to keep a lavender plant in your garden. But, as you do know, this perennial plant is a definite value addition to outdoor gardens. As it happens, the attractive scent from the plant is powerful enough to keep spiders away as well. Here is the problem with lavender, though. Growing the plant indoors is not as easy as keeping it in an outdoor garden. Even if you are growing it outside and using it as the sole spider-repellent element, you should keep the plant in check all the time. The plant may face stunted growth during the winter season when it does not get enough sunlight.


#3 Basil

Most varieties of basil plants are great at repelling spiders. Once again, you do not harm the spiders in any way. But the spreading smell from the basil plant will keep a distance between spiders and your garden. The good thing about basil is that it can survive in different living conditions, including indoor and outdoor ones. Of course, you have to ensure that the plant gets direct sunlight for a good 4 or 5 hours every day. You may have to add something to the package if the environment becomes very cold. If we keep these apart, basil plants will do a great job of keeping your garden spider-free.

#4 Chrysanthemums

Looking at Chrysanthemums, you would never think of getting insects killed, right? But, as it happens, pyrethrins from these plants are common ingredients in natural pesticides. Therefore, keeping one of these plants in your garden can keep spiders far away. Here is the problem, though. Unlike other plants, you have to ensure that chrysanthemums are always flowering. Most of the scents are coming from the flowers and not the leaves. So, you would have to remove dead flowers so that newer ones can blossom. But, as long as you have a few flowers on the plant, a Chrysanthemum can effectively keep your garden free from spiders.

#5 Lemon Balm

Lemon Balm is another plant you can use to keep spiders away from your indoor or outdoor garden. Thanks to its strong smell, the plant can also keep fruit flies away. You would not be surprised if other insects also stay away from your garden after you have planted Lemon Balm. Like peppermint, though, Lemon Balm is also very aggressive in the garden.

#8 Onions

Onions are perfect when it comes to warding off spiders. Once again, we have to thank the smell of the plant and its components for the said effect on spiders.

#11 Eucalyptus

Eucalyptus is another plant that you can bring into your garden as a tool against spiders. The problem with Eucalyptus is that they are not small plants.

First, you can find a place where you would not mind having a Eucalyptus tree. The other option is to find a dwarf variety of the tree, which is common. Regardless of the size, the Eucalyptus tree will maintain the rich scent, keeping spiders away.
