6 snake-repellent plants to naturally protect your home

Although no plant can completely repel snakes, some herbs and flowers are thought to make outdoor and garden areas less appealing to snakes. Some of these plants have strong scents or textures that snakes find less appealing. Combining these plants with proper garden maintenance, such as removing debris, mowing high grass, and patching holes, can help minimise the possibility of snakes being in or around your house.

Below are six plants often recommended for natural snake deterrence:

Marigolds are beautiful annual flowers that are easy to grow and have two uses: they are lovely to look at, and they have a strong scent from their leaves and roots that snakes are thought to dislike. Marigolds are also known to repel other garden pests like nematodes and insects, making them an excellent choice. Plant marigolds around the edges of your garden or near the entrance of your house to create a scented barrier around your home.

Lemongrass is a tall, tropical grass that has a strong citrus scent, which is overwhelming to many species of snakes. The scent of lemongrass is due to citronella oil, which is also used in many insect repellents. Planting lemongrass in a clump around the perimeter of your garden or entrance will help you create a scent-rich natural barrier that will keep snakes and other pests away. It is also a drought-resistant plant that thrives in tropical weather.

Members of the allium family, including garlic, onions, and chives, contain strong sulfur compounds that are distasteful to most snakes. Garlic can be grown in planters or in garden beds to offer both culinary and repellent functions. The smell of garlic is quite strong even in low light conditions, and onions are a good addition to the garden for aesthetic and functional purposes to help build an aroma barrier against snakes.

Cacti and other spiny succulents are not repellent by scent but by physical deterrent. The spines of cacti and other spiny succulents provide a hard terrain for snakes to slither through, making it less attractive to them. Planting cactus species around the foundation or paths can provide a thorny barrier that snakes will avoid. This makes cactus a very effective repellent in arid environments.

Wormwood is an herbaceous plant with silvery leaves and a very strong, bitter smell. The smell of wormwood, which comes from essential oils, can be used in folk gardens to repel pests, such as snakes. Wormwood performs well in garden borders or planters, and because it is drought-tolerant and hardy, many gardeners find it easy to maintain. Plant wormwood around entry points or fencing to help create a barrier against snakes.

Also known as Sansevieria, the snake plant has tall, stiff leaves with pointed tips. Although its common name doesn’t come from actual snake-repelling science, many gardeners believe that its sharp, vertical foliage makes snakes less inclined to pass through dense groupings of these plants. Snake plants are highly adaptable and can thrive indoors or outdoors with minimal care, making them a versatile addition near doors, paths, or patios.

Although scientific data on the efficacy of plants in repelling snakes is not extensive, many of these plants, including marigolds, lemongrass, garlic or alliums, cacti, wormwood, and snake plants, have characteristics that repel snakes by making certain areas less desirable to them. When paired with habitat modification, the use of these plants can help one adopt a more confident, natural method of snake repellent without relying on chemicals or snake traps.
