What Plants Do House Spiders Hate?
It’s not a new idea to use plants to repel spiders. People have been using natural ways to repel mosquitoes and other flying insects for years, much like moth balls used to repel spiders.
People find that plants that keep spiders away are also effective against cockroaches and other pests. However, while using such aromatic plants can help stop spiders from entering, it may not be enough to coax them back outdoors if they are already in your home.
One of the key advantages is using the plants to create an indoor garden or enhance your outdoor landscape.
Here are a few plants that spiders hate and are suitable to grow if you have a green thumb or not.
1. Dill (Anethum graveolens)
Dill is well-known for its culinary purposes. Because it isn’t a vigorous plant, many people don’t realize it may repel spiders and other bugs. Plant dill straight in your garden or in containers on your windowsills to repel unwelcome pests.
2. Osage Orange (Maclura pomifera)
The Osage orange is a hedge or hedge apple tree. This medium-sized tree or large shrub is ideal in regions where spiders are abundant, rather than just a few. The fruit is the most intriguing feature of this tree.
The fruit skin exudes an oily substance with a citrus scent. The fruit of the tree repels spiders and other insects, not the tree itself. You’ll see fruit blossom in April and June.
To prevent pests, cut ripe fruit in half and arrange it on windowsills and flower beds. It needs full light and regular watering, but let the soil dry between waterings.
3. Lemon Balm (Melissa officinalis)
Lemon balm plants can repel fruit flies as well as deterring spiders. Lemon balm is a member of the mint family and is commonly used to flavor food and beverages. The lemon-scented leaves are used to flavor drinks, salads, and meat.
Lemon balm thrives in temperate settings, not hot and humid ones. In cold areas, it dies back to the ground and reemerges in the spring. But it prefers full sun.
The plant needs well-draining moist soil with a pH of 6.7-7.3. In a container, the plant prefers slightly damp soil. Overwintering in a protected environment is required.
4. Rosemary (Rosmarinus officinalis)
No matter how many rosemary plants you use, you will still get spider mites and whiteflies. But cats despise rosemary. In colder locations, rosemary should be grown in pots or containers as it does not survive cold. Using a few pots, you can bring plants indoors throughout the winter.
Plant outside in zones north of 7 against a south-facing wall as brick keeps the plant warmer and protects it from hard winter winds. Rosemary needs full sun to thrive. Soil evenly moist with a pH of 6–7.
5. Citronella Grass (Cymbopogon citratus)
Citronella is a member of the lemongrass family and a great spider and mosquito repellent plant. This plant is the source of citronella oil, which is used in many insect repellents. Lemongrass or citronella is easy to grow but not winter-hardy. It should be grown in pots so it can be brought indoors during bad weather. Lemongrass thrives in full light and well-drained soil, whether planted in the ground or pots and containers. (Read Plants That Repel Skunks)
Brushing against the leaves or breaking them releases pest-repellent oils. Make a natural fly spray with crushed leaves.
6. Eucalyptus (Eucalyptus spp.)
Eucalyptus has a distinct smell and can grow impressively in Zones 8 through 10. The scent can help deter spiders and most other bugs. Gardeners opt for dwarf varieties of garden plants rather than a full-grown eucalyptus tree.
Indoors they need continuous trimming as a plant or shrub. Bring the plant indoors or grow it annually for winter protection and place it in a southern-facing window for full sun in well-drained soil with liquid food once per week.
7. Lemon Verbena (Aloysia citrodora)
Lemon Verbena is a fantastic insect repellent. Use well-draining organic fertile soil in pots or outdoors. The secret to keeping this plant alive is good drainage; if the roots get moist, the plant dies.
Too much shade causes spindly leaves and low essential oil levels. Like many herbs, Lemon Verbena requires frequent fertilization. You can overwinter lemon Verbena, but it’s better for the plant if you don’t.
What Do Spiders Hate?
Mint plants make up a large family, and all of them make excellent spider repellent plants. Mint plants may swiftly expand, so monitor their growth.
Mint plants are low-maintenance, and outdoors, a small layer of mulch helps keep them hydrated. Keeping indoor plants hydrated is vital, yet don’t overwet the soil. (Read Can Dogs Eat Mint Leaves)

Outdoors, choose a site that receives at least six hours of direct sunlight per day. The soil should have a pH between 7 and 8, making it alkaline rather than acidic.
Add lime to your soil to reduce acidity. Plant lavender in dry, well-draining soil. Bushes need pruning at least once a year to promote fresh blooms and prevent woodiness.
Chives (Allium schoenoprasum)
Easy to grow and maintain. Chives are a terrific addition to any herb garden. One of the best things about chives is their adaptability. Growing chives need a lot of sunlight and water.
Using chives in cooking is simple: snip off what you need and leave the stem to grow. Chives produce blooms on separate branches from the main stems, which are stronger.

For people who do not live in a subtropical region, dwarf citrus trees are a great alternative. Dwarf lemon trees are around ten feet tall and produce the same size fruit as conventional trees. Many individuals think dwarf trees produce more fruit.
Dwarf trees can be grown indoors or in gardens where a full-size tree would be too big. The key to growing dwarf citrus trees in pots is lots of sunlight. These trees need eight hours of daylight per day.
Keep the soil moist but not soaked. Feed your citrus tree as directed by the manufacturer. Bring trees inside during cold weather or wrap them in burlap, plastic, or a blanket.
Onion (Allium cepa)
By planting onions, you’ll have one of the few plants that repel spider mites and keeping spiders away. Onions are a hardy cold-season crop that is easy to grow. Sow onions in the spring and harvest in the fall.

Consider Chrysanthemums, formerly known as Pyrethrum, are plants that repel spiders and almost every other bug. This includes Japanese beetles, silverfish, ticks, roaches, ants, bed bugs, and spiders. This flower’s effectiveness as an insect repellant has led to its inclusion in several products.
These flowers demand well-draining soil but can adapt to other soil types. They do well in light shade but prefer full sun.
If you are repelling spiders in your flower beds or from your vegetable garden or discouraging rabbits from eating the rest of your plants, planting marigolds is the way to do it. Marigolds also repel gnats with their attractive foliage. Marigolds, an annual flower, add color and charm to any garden and are easy to grow and can be added to hanging baskets.
Plant tall American Marigolds after the last frost. Start the seeds indoors, but since they germinate swiftly outdoors, there is no real benefit.
What Scent Do All Spiders Hate?
Place cotton balls soaked in peppermint oil in the corners of your house to repel spiders. They are stunning to look at and have the benefit of a cotton ball.
Mint, chives, basil, lemon thyme, and other herbs are effective spider repellents. These herbs are used in cooking and can be dried and used as natural pest control methods.
