Planting specific plants in the courtyard can effectively prevent snake invasion. These plants usually have odors, shapes, or characteristics that snakes do not like, which can deter or drive away snakes. Here are some recommended anti snake plants:
1. Marigold: Marigold flowers are golden yellow in color, have a long flowering period, and can emit a strong odor that snakes do not like - thioethylene. The root system of marigold is lush, and its pungent odor can penetrate deep into the soil, preventing snakes from digging holes and hiding in the courtyard.
2. Impatiens: Impatiens, also known as fingernail flower, has bright flowers, a long flowering period, and can emit a special odor that has a strong repellent effect on snakes. Meanwhile, Impatiens also has certain medicinal value and is a plant that combines ornamental and practical use.
3. Wild Cassia Ming (Snake Mie Men): Wild Cassia Ming is widely recognized as the "snake killer star" in Chinese folklore. After flowering, its entire plant emits a special odor that is extremely sensitive to snakes. When snakes smell it, they will quickly flee. However, wild cassia has certain toxicity, and safety should be taken into account when planting and using it.
4. Gangbangui (Snake Backward): Gangbangui is a creeping plant with many thorns on its stem that can prick the snake's skin, causing it to feel pain and be afraid to approach. This plant is very common in rural areas and grows rapidly with strong reproductive ability. It is suitable for planting around courtyards to drive away snakes.
5. Holly tree: The prickly leaves of holly make it uncomfortable for snakes to glide over, and its strong scent also makes snakes avoid it. Holly trees also have certain ornamental value and are a good choice for courtyard greening.
6. Lemongrass: Lemongrass is known for its refreshing citrus aroma, but this scent is overwhelming for snakes and can deter them. Planting lemongrass outdoors can resist the invasion of snakes.
7. Cactus: Like holly trees, snakes also avoid prickly plants, so cacti are also a good choice for snake prevention. Planting cacti around the courtyard can protect your property from snake infestations.
8. Lilac basil: Lilac basil has a unique clove flavor that snakes do not like. Sprinkle clove and basil herbs around the soil and plants to effectively prevent snake invasion.
Although these plants have a certain anti snake effect, it cannot guarantee that snakes will no longer appear. While planting these plants, it is also necessary to combine other snake prevention measures, such as keeping the courtyard clean, repairing damaged fences, and conducting regular inspections, to create a safer living environment.
