For centuries, people have looked for safe and simple ways to keep venomous snakes away from their homes. While scientific evidence is limited, several traditional remedies are widely believed to discourage snakes from coming too close.

1. Lemongrass – The Herbal Barrier

Lemongrass is well known for its sharp, citrus-like fragrance. Many households in Asia plant it around their gardens not only for cooking but also because its strong aroma is thought to deter snakes.

• Essential oil use: If you don’t grow lemongrass, its essential oil can be used. Diffusing the oil indoors two to three times a week may create an environment snakes avoid.
• Cotton ball method: Soak cotton balls in lemongrass oil and place them near doors, windows, or dark corners. Replace them once the scent fades.
• Spray method: Mix lemongrass oil with water in a spray bottle and apply it to entryways or areas where snakes might hide.

2. Salt and Garlic – A Simple Household Mix

A more accessible option is a mixture of coarse salt and crushed garlic, combined in equal parts. Sprinkled around doors, gardens, or outdoor spaces, this blend is believed to discourage snakes from crossing.

• If a snake has already entered the house and is hiding in confined spaces like cabinets or drawers, do not attempt to handle it. Evacuate the area and contact professionals for safe removal.

• In less dangerous encounters, a gentle spray from a garden hose can sometimes encourage a snake to leave on its own.

3. Realgar Powder – A Traditional but Risky Deterrent

Realgar, or arsenic sulfide, has historically been used as a snake repellent because of its strong odor and toxic nature. The bright orange-yellow powder was once sprinkled around homes and paths to keep snakes away.

Important caution: Realgar is toxic not only to snakes but also to humans and pets. Direct contact or contamination of food and water can be dangerous. If used at all, gloves and protective handling are essential, but many experts advise against it due to safety concerns—especially in households with children.

4. Preventive Measures – The Most Reliable Approach

While natural scents and powders may help, the most effective way to reduce snake encounters is by making your environment less inviting:

• Keep grass trimmed short and remove piles of wood, debris, or thick vegetation where snakes may hide.
• Seal cracks, gaps, and entry points around the home.
• Maintain a clean yard and limit rodent activity, since snakes often follow prey.

Final Note

Folk remedies like lemongrass, realgar, and garlic-salt mixtures are widely discussed in communities, but they should not replace practical prevention or professional help when dealing with venomous snakes. A combination of natural deterrents and good property maintenance is the safest way to minimize risk.
