8 plants snakes tend to avoid—plant these to make your yard less inviting

Quick truth check: no plant “repels” snakes like a force field. What actually helps is (1) making the area uncomfortable to travel through, (2) reducing cover, and (3) lowering food sources (insects/rodents). The plants below are popular because their scent, texture, or structure helps on one or more of those fronts. Use them as part of a tidy-yard strategy (short grass, sealed gaps, no debris piles).

1) West Indian lemongrass / citronella grass (Cymbopogon citratus / nardus)

• Why it helps: Strong citrusy oils can mask scents and reduce insect activity (less prey = fewer snake visitors).

• How to use: Full sun, well-drained soil. Plant in clumps along paths or near patios.

• Notes: Sharp leaf edges—wear gloves when trimming.

2) Marigold (Tagetes spp.)

• Why it helps: Pungent foliage and root compounds discourage some pests; bright borders also keep ground open and visible (snakes avoid exposed crossings).

• How to use: Edge beds and foundation lines 20–30 cm apart for a low, continuous band.

• Notes: Deadhead blooms to keep a dense, tidy border.

3) Garlic (and other alliums)

• Why it helps: Strong sulfur scent; can deter rodents/insects that attract snakes.

• How to use: Interplant garlic, chives, or ornamental alliums around sheds and along fences.

• Notes: Mildly upsetting if pets chew bulbs—plant where pets don’t dig.

4) Rue (Ruta graveolens)

• Why it helps: Bitter, resinous aroma; long used in folk gardens around perimeters.

• How to use: Full sun; drought tolerant once established; space 40–60 cm.

• Notes: Phototoxic sap—can irritate skin if handled in sun. Wear gloves.

5) Wormwood (Artemisia absinthium and relatives)

• Why it helps: Silvery, aromatic foliage; discourages many insects and creates a dry, open understory.

• How to use: In poor, well-drained soil where you want sparse ground cover (less hiding).

• Notes: Avoid overplanting—can spread. Keep away from edible beds.

6) Peppermint / spearmint (Mentha spp.) (in containers)

• Why it helps: Strong mint oils; can help push back rodents near garbage or compost areas.

• How to use: Pot only (mint is invasive). Place containers along walls, near bins, or gaps under stairs.

• Notes: Refresh regularly and trim to prevent runners.

7) Rosemary (Salvia rosmarinus)

• Why it helps: Woody, aromatic shrub that forms dense, scratchy hedges—uncomfortable to pass through and easy to keep low around walkways.

• How to use: Full sun; hedge spacing 50–80 cm; light annual shear for a tight barrier.

• Notes: Drought tolerant; great for coastal or warm climates.

8) Thorny barrier shrubs (e.g., bougainvillea, barberry, pyracantha)

• Why they help: Physical deterrent. Thorns + dense branching create a hostile edge snakes dislike crossing.

• How to use: Plant as a perimeter hedge beneath windows/fence lines where you want a living barrier.

• Notes: Keep clear of walkways; wear protective gloves when pruning.

Where to put them (simple layout that works)

• Perimeter band (first line): alternate rosemary and a thorny shrub every 60–80 cm to build a dense, low hedge.

• Scent band (second line): in front, dot lemongrass, marigold, and alliums to add scent and reduce insect/rodent appeal.

• Hot spots: containers of mint near bins, sheds, or stair gaps; a few clumps of wormwood/rue where ground tends to stay weedy.

---

Yard habits that multiply the effect

• Cut cover: Keep grass short, trim the base of shrubs so you can see the soil, and avoid deep groundcovers that create tunnels.

• Remove magnets: Clear wood/rock piles, stacked tiles, and unused lumber. Elevate firewood off the ground.

• Rodent control: Secure trash, use tight-lidded bins, and harvest fallen fruit—remove the food, remove the hunters.

• Seal entries: Fill gaps under steps, around sheds, and along fence bottoms with gravel or hardware cloth.

Important caveats & safety

• These plants reduce attractiveness; they don’t guarantee a snake-free yard.

• Some are irritating or mildly toxic if touched/ingested (especially rue, wormwood, barberry). Keep out of reach of curious kids and pets; wear gloves to prune.

• If you see a snake inside the home or an aggressive species outdoors, don’t attempt removal—contact local animal control or a licensed wildlife handler.

Quick starter list (shopping card)

• 3–5 lemongrass clumps

• 12–20 marigold seedlings (border pack)

• 6–10 garlic or ornamental allium bulbs

• 2 rue, 2 wormwood (sunny, dry spots)

• 2–4 rosemary shrubs (hedge)

• 2 thorny barrier shrubs suited to your climate (e.g., bougainvillea, barberry)

• 2 large mint pots (for containers)

Bottom line: Choose aromatic, structural, and thorny species to make paths open, edges uncomfortable, and prey less abundant. Combine smart planting with tidy yard habits, and your property becomes a place snakes are far less likely to visit.
