Making homemade snake repellent takes under 10 minutes and requires protective gloves, a face mask, two buckets, powdered sulfur, mothballs, a zip-top freezer bag and cat litter. Mixing the crushed mothballs with cat litter for indoor use and sulfur for outdoor use produces cost-effective and safe repellents.
- Prepare to make the snake repellent
Bring the supplies outside or into a well-ventilated room. Put on protective rubber gloves and a face mask.
- Crush the mothballs
Put 2 cups of mothballs into a zip-top freezer bag. Squeeze most of the air out of the bag and seal it tightly. Put it on the ground and crush the contents by walking on the bag. Pulverize the mothballs until no large pieces remain.
- Mix the indoor repellent
In one of the buckets, combine equal parts cat litter and mothball crystals. Toss the mixture with your gloved hands.
- Mix the outdoor repellent
In the other bucket, combine equal parts mothball crystals and powdered sulfur. Mix the repellent with your gloved hands.
- Place the repellents
Scatter the outdoor repellent around your property, including in crevices, covered areas and corners. Due to its strong odor, keep this repellent away from windows and air vents. Use the indoor repellent near windows and air vents instead. The indoor repellent is also effective on front porches and in basements and garages.
