Certain plants can help keep copperhead snakes away from your yard.
If you’ve been wondering what plants keep copperhead snakes away, the answer lies in strong-scented, thorny, or dense foliage that snakes naturally avoid.
Plants that keep copperhead snakes away work by disrupting their sensory cues or making areas uncomfortable for them to slither through.
Copperheads rely on smell and vibration to hunt and hide, so the right greenery can confuse or repel them.
In this post, we’ll explore what plants keep copperhead snakes away, how they work, and where to place them for the best results.
Let’s jump right into the most effective plants that keep copperhead snakes away from your home.
What Plants Keep Copperhead Snakes Away?
Several specific plants are known to deter copperheads, and they fall into a few key categories.
Here’s a look at the top contenders for what plants keep copperhead snakes away:
1. Marigolds
Marigolds are a classic choice among plants that keep copperhead snakes away.
Their strong, pungent scent, especially from the roots, is off-putting to copperheads.
The bright blooms also attract pollinators, which helps your garden thrive while repelling snakes.
Plant marigolds in borders or near entry points to create a natural snake barrier.
2. Lemongrass
Lemongrass is another powerful option when considering what plants keep copperhead snakes away.
It contains citronella oil, which masks the scents snakes use to find prey.
The tall, dense growth also makes it hard for copperheads to move through undetected.
Place lemongrass around garden beds or along fence lines for maximum effect.
3. Wormwood (Artemisia)
Wormwood has a bitter, strong aroma that copperheads dislike intensely.
As one of the most effective plants that keep copperhead snakes away, wormwood can be grown as a border plant.
Its silvery foliage also adds visual interest while serving as a natural repellent.
Just keep it away from edible crops since its oils can affect nearby plants.
4. Garlic and Onions
Garlic and onions release sulfur compounds into the soil and air.
These compounds irritate a copperhead’s sensitive Jacobson’s organ, encouraging them to leave.
What plants keep copperhead snakes away better than a double-purpose crop you can also harvest?
Plant them in clusters around patios or vegetable gardens as a living repellent.
5. Rosemary
Rosemary’s woody, aromatic scent is pleasant to us but unpleasant to copperheads.
Its sprawling, low-growing habit creates a dense mat that snakes avoid.
Rosemary is drought-tolerant and easy to maintain, making it a low-effort addition to your snake-deterring lineup.
How Do Plants Keep Copperhead Snakes Away?
Understanding the mechanism helps you pick and place these plants more effectively.
Here’s why these plants that keep copperhead snakes away actually work:
1. Strong Smells Overpower Snake Senses
Copperheads rely heavily on smell to hunt and sense danger.
The potent oils in plants like marigolds, lemongrass, and wormwood confuse their olfactory system.
What plants keep copperhead snakes away by simply being too pungent for their sensitive noses?
Any plant with a sharp, lingering scent can achieve this effect.
2. Prickly or Rough Textures Deter Movement
Snakes prefer smooth, open ground for easy slithering.
Plants with thorns, bristly leaves, or dense growth create physical barriers.
Another reason why certain plants that keep copperhead snakes away is the uncomfortable surface they create.
For example, holly or rose bushes (though not scented) also discourage snakes, but the plants listed above combine texture with smell.
3. Disrupted Habitat and Prey Availability
Copperheads hide in tall grass, leaf litter, and underbrush.
By replacing those hideouts with low-growing, aromatic plants, you remove their cover.
Plants that keep copperhead snakes away also reduce the presence of rodents and insects they feed on.
A well-planted yard becomes less inviting to both snakes and their food sources.
Best Placement for Plants That Keep Copperhead Snakes Away
Where you put these plants matters just as much as what plants keep copperhead snakes away.
Follow these tips to maximize their repellent power:
1. Ring the Perimeter of Your Property
Create a continuous border of these plants around your yard or garden.
Copperheads are unlikely to cross a thick, fragrant barrier to reach your home.
Make sure the barrier is at least a few feet wide for best results.
2. Focus on Entry Points
Place pots or beds near doors, garage entrances, and basement windows.
What plants keep copperhead snakes away from your house? The ones you put right where they’d try to enter.
Garlic and rosemary work especially well in planter boxes near entryways.
3. Mix and Match for Year-Round Coverage
Some plants die back in winter, so combine perennials like rosemary with annuals like marigolds.
This ensures you always have plants that keep copperhead snakes active in every season.
Also, consider using straw or hay as mulch—it’s a natural snake repellent too.
