How to use lemongrass oil to keep lizards away: Easy tricks to stop these unwanted guests from climbing your walls

House lizards are common in many homes, especially during warmer months when insects become more active. While they are mostly harmless, plenty of people would still rather not see them crawling across walls at night.

One natural remedy that may help is lemongrass oil. Its strong citrus scent can make certain areas less attractive to lizards and may also reduce the insects they feed on.

Here’s how to use lemongrass oil properly to help keep lizards away from your home.

Why Lemongrass Oil May Help Repel Lizards

Lemongrass has a strong citrus scent
Lemongrass oil contains compounds such as citral, which give it a powerful smell. While there is limited scientific research specifically proving that lemongrass oil repels house lizards, many people use it as a natural deterrent.

The stronger benefit is often indirect, the scent may help reduce insects in some areas, making your home less attractive to lizards looking for food.

Best Places to Use Lemongrass Oil

Apply it near:

• Windows
• Balcony doors
• Kitchen corners
• Behind cupboards
• Near tube lights or outdoor lights
• Cracks and wall gaps where lizards appear

Avoid spraying directly onto pets, food surfaces or electrical outlets.

How to Make a Lemongrass Oil Spray

Simple DIY lemongrass spray recipe
You will need:

• 10–15 drops of lemongrass essential oil
• 1 cup of water
• A small spray bottle
• A few drops of mild liquid soap (helps the oil mix with water)

Steps

• Pour the water into the spray bottle
• Add the lemongrass oil
• Add a few drops of liquid soap
• Shake well before each use
• Spray lightly around entry points and problem areas

Reapply once or twice daily for the best results.

Use Cotton Balls for Stronger Scent

Another easy method is soaking cotton balls in lemongrass oil and placing them in spots where lizards usually appear.
Good locations include:

• Behind furniture
• Under sinks
• Near windows
• Inside cupboards
• Around shoe racks

Replace the cotton every few days once the smell fades.

Combine Lemongrass Oil With These Tips

Lemongrass oil works better when combined with basic lizard prevention methods.

Reduce insects indoors
Lizards stay where insects are available. To reduce bugs:

• Keep food covered
• Don’t leave dirty dishes overnight
• Use window mesh
• Switch off unnecessary lights at night
• Fix damp corners and leaks
• Seal entry points

Small gaps around windows, pipes and doors make it easy for lizards to enter.

Use:

• Silicone sealant
• Door sweeps
• Fine mesh screens

Is Lemongrass Oil Safe Around Pets and Children?

Lemongrass oil should always be used carefully.

Important safety tips

• Do not let pets lick concentrated essential oil
• Keep oils away from cats, birds and fish tanks
• Avoid spraying directly onto skin
• Use diluted oil only
• Store bottles out of children’s reach

If anyone in the home has asthma or scent sensitivity, use small amounts first.

Does Lemongrass Oil Actually Work?

Lemongrass oil is not a guaranteed fix, but many people find it useful as part of a broader pest-control routine.

It works best for:

• Mild lizard problems
• Preventing lizards from returning
• Keeping balconies and windows less attractive to insects

If you have a serious infestation, you may need professional pest control along with home sealing and insect reduction.
