Can Salt Kill Lizards

When it comes to lizards, salt can be a deadly substance. Salt absorbs moisture from the lizard’s body and causes them to become extremely dehydrated, which can lead to death. Another way that salt can kill lizards is by burning them.

If the salt gets into their eyes, it can cause them to swell and turn white.

This can eventually lead to blindness.

While salt is often used as a natural remedy for pest control, it is not recommended for getting rid of lizards.

Instead, there are more humane and effective ways to keep lizards out of your home.

Some natural remedies include using lemongrass or peppermint oil, which are known to repel lizards.

You can also use physical barriers such as mesh screens or door sweeps to keep lizards from entering your home.

It is important to note that not all lizards are harmful.

In fact, many species of lizards are beneficial to the environment as they eat insects and other pests.

Therefore, it is important to take a humane approach when dealing with lizards and to only use methods that do not harm them.

How Salt Affects Lizards’ Bodies

Salt impacts lizards by causing dehydration and irritation. When lizards come into contact with salt, it absorbs moisture from their bodies, leading to extreme dehydration.

This can be fatal to the reptile as it loses essential fluids necessary for survival.

Moreover, salt can also cause burns and irritation to the lizard’s skin and eyes.

In cases where salt gets into their eyes, it can cause swelling and a white appearance.

This may eventually lead to blindness, significantly impacting the lizard’s quality of life and ability to search for food or avoid predators.

It is important to note that not all salts or chemicals will have the same effect on every lizard species.

Different lizards may show varying levels of sensitivity to these substances, depending on their size, habitat, and overall physiology.

However, in general, excessive exposure to salt or other harsh chemicals can be detrimental to the health and well-being of lizards.

There are many other effective and humane methods to get rid of lizards, such as using natural repellents or sealing off entry points.

What Happens When Lizards Ingest Salt

If lizards ingest salt, it can lead to severe health problems.

Salt can cause an imbalance in their electrolytes, which can affect their nervous system and lead to seizures, tremors, and even death.

Additionally, salt can cause kidney damage and other internal organ damage in lizards.

It is important to note that using salt to kill lizards is not a humane method and should be avoided.

How to Keep Lizards Away with Salt

Lizards are harmless creatures, but they can be a nuisance when they invade your home.

If you’re looking for a natural way to keep them away, salt can be a useful tool. Salt is an effective repellent that can help keep lizards away from your home.

Here are a few ways to use salt to keep lizards at bay:

1. Salt Barrier

One way to use salt to keep lizards away is to create a salt barrier around your home. Sprinkle a line of salt around the perimeter of your home, especially near doors and windows.

This will create a barrier that lizards will not want to cross. However, be careful not to use too much salt, as it can be harmful to plants and grass.

2. Salt Solution

You can also create a salt solution to spray around your home.

Mix salt and water in a spray bottle and spray it in areas where lizards are likely to hang out, such as near windows, doors, and other entry points.

This will create an unpleasant environment for lizards and discourage them from coming into your home.

3. Salt Lamps

Salt lamps are another way to keep lizards away.

These lamps are made from Himalayan salt and emit negative ions that can repel lizards and other pests.

Place a salt lamp in areas where lizards are likely to enter, such as near windows and doors.

While salt can be an effective way to keep lizards away, it’s important to remember that it can be harmful to plants and grass.

Use salt sparingly and avoid using it in areas where it may come into contact with plants or grass.

Additionally, be sure to clean up any salt residue to prevent damage to your home or yard.

Other Natural Lizard Repellents

Garlic and Onion

Garlic and onion are excellent natural repellents to get rid of lizards.

The pungent aroma of these plants is known to irritate the lizards’ olfactory system, causing them to avoid areas where the smell is present.

Placing crushed garlic or onion pieces near windows, doors, and other entry points can effectively deter lizards from entering your home.

Pepper Spray and Hot Sauce

Another effective method to repel lizards is by using pepper spray or hot sauce.

Capsaicin, the compound responsible for the hot sensation of peppers, can also irritate lizards.

Create a mixture of water and hot sauce in a spray bottle, or alternatively, mix crushed hot pepper with water.

Spraying this solution around the perimeter of your home, particularly near entry points, can help keep lizards at bay.

Eggshells and Coffee Powder

Lizards are repelled by the smell of eggshells, so strewing these around your house can help keep them away.

Save the shells from eggs you consume, then place them near doors and windows to serve as a deterrent.

Additionally, combining coffee powder with tobacco powder can create an effective mixture to kill lizards. Roll them into small balls to make your own lizard death-balls.

Lemongrass Essential Oil

Lemongrass essential oil is another natural lizard repellent.

Its strong citrus scent is unappealing to them. You can make a repellent spray by mixing a few drops of lemongrass oil with water in a spray bottle.

Frequently spraying this solution near potential entry points can help deter lizards from entering your home.

Peacock Feathers

Peacock feathers are also an effective way to keep lizards away.

Lizards are instinctively afraid of peacock feathers, as they resemble the feathers of a potential predator.

You can place peacock feathers near windows and doors to discourage lizards from approaching those areas.

By using these natural lizard repellents, it’s possible to humanely keep lizards away from your home without causing harm to them.

Try one or a combination of these methods to develop a lizard-free living space.

Cold Water and Tabasco Sauce

Cold water can be an effective method to repel lizards.

When lizards come into contact with cold water, they may become sluggish and eventually retreat to a warmer area.

Along with cold water, Tabasco sauce can be used as a powerful, spicy deterrent.

Lizards are repelled by strong, spicy scents like Tabasco sauce, so mixing it with cold water and spraying it in strategic areas can help keep them away.

Just be sure to spray it in nooks and crannies where lizards are likely to hide and refresh the mixture periodically to maintain its effectiveness.

Naphthalene Balls and Phenyl Tablets

Naphthalene balls are also an effective home remedy for lizard control.

By placing them around your home, especially near doors and windows, you can create an unpleasant environment for lizards that will discourage them from entering.

Similarly, phenyl tablets emit a strong smell that is unappealing to lizards.

Placing these tablets in areas where lizards are likely to hide can also help to keep them at bay.

Diatomaceous Earth

Diatomaceous earth (DE) is a natural, non-toxic substance made from the fossilized remains of tiny, aquatic organisms called diatoms.

It works as an effective desiccant, which means it can effectively dehydrate lizards by absorbing the moisture from their bodies.

Sprinkle DE in areas where lizards frequent, such as near entry points, along baseboards, and in cracks and crevices.

Be sure to wear protective gloves and a mask while handling DE, as it can cause irritation to the skin and respiratory system if inhaled.

Safety Considerations and Precautions

When dealing with the use of salt to potentially exterminate lizards, it is essential to take certain safety measures to protect oneself, pets, and children.

The following paragraphs outline the necessary precautions to keep everyone safe.

First and foremost, wearing gloves is highly recommended while trying to apply salt to lizards.

Gloves play a crucial role in protecting you from potential bites and scratches.

Ensuring that you do not touch your face or mouth with the gloves on can prevent the spread of any germs or bacteria from the lizard to your body.

In addition to gloves, it is advised to wear protective clothing such as long sleeves, pants, and boots while handling chemicals or substances that could harm lizards.

This will help minimize the risk of direct contact with potentially harmful substances, especially when using different chemical pesticides.

If pets or children are present in the area where the extermination is taking place, it is crucial to keep them at a safe distance.

Lizards and some chemical substances can pose a threat to their health.

It may even be beneficial to remove pets and children from the area until the extermination process is complete and the space has been thoroughly cleaned.

Preventing Lizard Infestations

Eliminate Food and Water Sources

One effective way of preventing lizard infestations is to eliminate their food and water sources.

Lizards feed on various insects like ants, flies, and bugs, so it’s essential to keep these insect populations under control. Some practical steps to achieve this can include:

  • Regularly clean your home and its surroundings.
  • Dispose of food waste properly and store food in sealed containers.
  • Use insect repellent sprays or traps to manage insect populations.

In addition to controlling insects, ensure there are no water sources available for lizards.

Fix any leaky pipes or faucets, and do not leave water in containers or pet dishes overnight.

Seal Entry Points and Hideouts

Lizards may enter your home through gaps, cracks, and other openings, so it’s crucial to seal off these entry points.

Identifying and sealing all possible lizard entry points will greatly reduce their chances of invading your living space:

  • Inspect walls, doors, and windows for small openings or cracks.
  • Seal spaces around pipes, vents, and utility lines.
  • Close off unused floor drains and openings in your basement or crawlspace.

Additionally, remove any potential hiding spots and shelter for lizards by decluttering your home and yard.

This includes pruning overgrown vegetation and maintaining a clean, organized outdoor area.

Install Window Screens

Another effective way to keep lizards out of your home is by installing window screens.

These provide a barrier against not only lizards but also various insects, which serve as their primary food source. Make sure to:

  • Measure your windows properly and choose screens that fit snugly.
  • Opt for fine-mesh screens to prevent even small insects from entering your home.
  • Make it a habit to close your doors and windows at night to keep both insects and reptiles out.


Overall, while salt may seem like a quick and easy solution to get rid of lizards, it is not recommended due to its inhumane nature. There are many other effective and humane ways to get rid of lizards that should be considered instead.
