Like the naphthalene in mothballs, ammonia is a chemical with a strong scent that snakes hate. Gardeners use it as a spray around homes and on rocks to keep snakes from crawling over them. It's scentless and invisible to humans, but that doesn't make it safe. Ammonia can kill snakes that crawl across it.
The truth is, snakes have a strong sense of smell, which they use to find accessible food sources. You can take advantage of this trait by using scents they dislike, such as cinnamon, clove oil, and eugenol. These are the only scents recommended by the Animal and Plant Health Inspection Service to repel snakes.
In locations where water is scarce, a diluted solution of nicotine sulphate is a good poison. Strychnine in eggs works for snakes that raid poultry houses. Calcium cyanide is a good chemical for killing snakes taking refuge in burrows, while there are several gases that sometimes work in fumigating dens.
Acrid oil, strong odor: Because snakes are creatures that do not like strong smells, so if you see snakes hanging around in the house, try to smell strong oils, such as engine oil, kerosene, turpentine, or car oil to the area around the house to help chase the snake away.
The fact remains that the scales of snakes are mainly designed to repel liquids. So, the chances of snakes absorbing the acidic content of vinegar are most likely not going to happen. However, snakes can stay away from white vinegar because it confuses their sense, (smell), and organs.
Sulfur: Powdered sulfur is a great option to repel snakes. Place powdered sulfur around your home and property, and once snakes slither across it; it irritates their skin so they won't return. Sulfur does give off a strong odour, so consider wearing a mask that covers your nose and mouth when applying it.
Some believe that pouring kerosene, diesel or concoctions made of garlic will stop snakes creeping into house premises. It is a myth. No chemical can act as a deterrent against such reptiles. Kerosene or other pungent substances may force snakes out of places where they are holed up when poured on them.
Other Natural Repellents
Essential oils — like Cinnamon, Eucalyptus, or Clove, mixed with water and sprayed around the area. Mothballs — place them around the perimeter, and their pungent smell will repel snakes.
Clove Oil: Snakes are sensitive to clove oil, which can be used as a natural repellent. Lemon Oil: Lemon oil contains citric acid and has a strong scent that snakes don't like.
If you have a snake in your house but you don't know where he is, sprinkle baby powder or flour lines across the entrances to each room. When the snake passes over the line, not only will he leave a track but he'll leave a trail for a short distance.
EnviroBug solar snake repellers are built to be the highest-quality, most powerful snake repellers available. Built to endure tough Australian conditions, Envirobug solar snake repellers are effective up to a 40-metre diameter - meaning you need fewer, and they will keep snakes further away.
Does Bleach Repel Snakes? The smell of bleach will repel snakes and if they drink it, it can kill them. However, you're more likely to cause harm to yourself, your pets, your children and your soil by using bleach than you are to deter snakes with it.
"Citrus fruits like lemons, oranges, and grapefruits contain a chemical called limonene, which is a natural snake repellent. Just place a few slices of citrus fruit around your home, or even rub the peel on the outside of your door and windows."
Ammonia can function as a snake removal agent as snakes hate its smell and won't come near it. Soak rags in ammonia and place them where you usually see snakes to drive them away. If you have a pool, you can use white vinegar to keep snakes away from it.
There are many scents snakes don't like, including smoke, cinnamon, cloves, onions, garlic, and lime. You can use oils or sprays containing these fragrances or grow plants featuring these scents to deter snakes from coming close to your property. This works as snakes also rely on smell to move around.
Exterminators Choice Snake Spray
One bottle of Exterminator's Choice Natural Snake Repellent is a bit more cost friendly and can make a 3 ft. barrier around a property. The product uses various essential oils (clove, peppermint, & cinnamon oil) and relies on a strong odor to keep serpents away.
A safe and effective snake deterrent is peppermint and other plants in the mint family. Because mint is such a strong smell, snakes hate the smell of it and will usually stay away. Mint can be planted in the ground or in pots. It's also effective as an essential oil or spray.
It's one of those fallacies that persist through the years and will undoubtedly continue to do so. The reason is simple—there is zero evidence that diesel works to repel a snake, or has ever worked. Though ingesting, inhaling, or otherwise absorbing it may be harmful to a snake, there is no evidence for that either.
Mothballs are commonly thought to repel snakes, but they are not intended to be used this way and have little effect on snakes.
If you want to deter snakes further, there are some natural plant essential oils that work when you combine them. These are 20ml each of tea tree oil, lavender oil, sandalwood, oil of cloves, and eucalyptus. You can add about 450ml of water to your spray bottle.
Keep all yards tidy and clear from loose ground cover: sheets of metal, hard rubbish etc. Remove overgrown weeds and creeping vegetation. Snakes love rock retaining walls especially where there are holes or access to water (such as a pool). Be sure to fill in all gaps with concrete or another hard substance.
Use natural materials, such as pine cones, sharp rocks, eggshells, or holly leaves, and lay out a surface that no snake would choose to slither across.
The best method to scare them is to make fast movements. A lot of times, just chasing the snake away works very well. Another thing to try is to stomp hard on the ground. The snake will not hear the noise, but it will get scared off by the vibrations the stomping makes.
