Will Eucalyptus Oil Kill Bed Bugs? (How To Use it?)

Will Eucalyptus Oil Kill Bed Bugs? (How To Use it?)

The pungent odor of eucalyptus oil, made from eucalyptus leaves, is disliked by bedbugs. It’s a natural way to get rid of bedbugs for those who don’t want to use insecticides that contain chemicals.

An infestation of bedbugs in your home can make things hard for you, your family, and pets. They’re annoying little pests that can prevent you from sleeping. Their bites are itchy and nasty. Bedbugs leave feces stains on your sleeping wear and your bedsheets.

When applied correctly, eucalyptus oil can help you get rid of bedbugs. You can spray eucalyptus oil once you’ve identified the areas they frequent. Make sure the oil is diluted to avoid irritation.

Does Eucalyptus Repel or Kill Bed Bugs?

Bedbugs can be repelled and killed with eucalyptus oil. If you have a minor infestation, you can keep the oil in your home until you need it. Add a few drops to your bedside table, and you can also add the oil to your cleaning detergents.

To kill bedbugs and any eggs laid by them, mix a few drops of eucalyptus oil into your laundry detergent and use it to clean your beddings. Insecticides or a professional pest controller would be more effective in cases of severe infestation.

In most cases, you will not have completely eradicated the bedbugs. You will still see a few after using insecticides or having a pest control professional come to your home. You’ll need to keep applying eucalyptus oil to get rid of the remaining ones.

How To Use Eucalyptus Oil For Bed Bugs?

While dealing with a bedbug infestation might be time-consuming. It’s a process that can take days before you’re entirely free of them. Don’t get tired of applying methods to help you reduce and eventually eliminate them.

Because you’ll be doing this multiple times, consider using eucalyptus oil, cheaper and more natural. We’ll outline five different ways to use eucalyptus oil to get rid of bedbugs.

  1. Eucalyptus oil burner: Fill your oil burner with water and a few drops of eucalyptus oil before lighting the candle. Place the oil burner near your bed or any other area where bedbugs have been spotted. To avoid burning down your house, keep an eye on your burner until the candle burns out.
  1. Eucalyptus oil mixture: Fill a spray bottle partly with water and add 30 drops of eucalyptus oil. Spray in all areas where you’ve seen bedbugs, including your bed.
  1. Add to cleaning equipment and products: Eucalyptus oil can be added to cleaning products such as detergents and sprays to ensure that places where bedbugs are spotted, are constantly sprayed. You can also dab some eucalyptus oil on the cleaning tools, such as sponges or cloths.
  1. Tea tree oil + eucalyptus oil: In a spray bottle, add 10 drops of tea tree oil, 20 drops of eucalyptus oil, and a cup of water. Mix thoroughly and spray the mixture on your bed and other areas that bedbugs seem to frequent. This mixture is more effective due to the addition of tea tree oil.
  1. Use a diffuser: Add a few drops of eucalyptus oil and some water to the diffuser. Place it near your bed or anywhere else where you have spotted the bedbugs.

Essential Oils To Get Rid of Bed Bugs

While eucalyptus oil is a highly effective way to get rid of bedbugs, you can also use other essential oils. Essential oils are liquid extracts from aromatic herbs that you can use as insect repellents or killers.

Essential oils are popular with people since they are non-toxic and chemical-free. Because of these two properties, you can spray around pets and children and on clothing and furniture. However, make sure to buy the ones that have been certified, as some may contain dangerous substances.

You can spray these essential oils on the areas surrounding your bed, such as the headboard and legs and your bed, bedsheets, and sleeping wear. Remember to spray them sparingly because they can be toxic if sprayed in large quantities.

When sprayed directly on bedbugs, essential oils are deadly and kill them immediately. Because not all essential oils are effective, we will only list a few.

1. Lavender Oil

While lavender oil is most commonly used to keep bedbugs away, it can also kill them on contact. Bedbugs are repelled by the oil rather than killed by it. It has a pungent odor that bedbugs dislike.

You can use the oil in cleaning detergents, laundry, mattress spray, and carpet cleaning.

Applying a lavender-scented lotion to your skin is an effective way to keep the pesky pests at bay. Because it is non-toxic, you can use it around children and pets. Lavender is also well-known for its calming effects.

2. Lemongrass/Lemon Oil

Lemongrass or lemon oil can be used to refresh your thoughts or to kill bedbugs. Citrus is included in both, making the oil effective. Because of its high acidity, you should dilute the oil to avoid harming your skin.

Citronellal and citronellol, powerful insect repellents, are high in lemongrass. Spray on your beddings, carpets, and mattress every few days, and add a few drops to your laundry load.

Applying a few drops of lemongrass oil to your bed can also help keep bedbugs away.

3. Peppermint Oil

Peppermint has a strong, pungent odor that keeps bedbugs away. While bedbugs loathe the smell, humans find it highly soothing for the body and mind.

After spraying, the pungent odor will keep bedbugs away for several hours. Peppermint should be blended with other insecticidal essential oils to make it more potent. In a spray container, mix 20 drops of peppermint oil with water and thoroughly shake.

Take the mixture and spray in all the areas that bedbugs frequent in your home. When you want to apply it to your skin, it is best to add some lotion or carrier oil to avoid irritating your skin.

Does Tea Tree Oil Kill Bed Bugs?

Tea tree oil is the next best essential oil after eucalyptus oil. It’s well-known for its insecticidal properties, and it can quickly eliminate bedbugs and their larvae.

Tea tree oil is a highly effective insecticide that kills bedbugs and other insects when they contact it. The bedbugs’ ducts are blocked, and they are unable to breathe. Experts recommend diluting it because it might cause skin irritation and allergic responses.

Simply combine a few drops of tea tree oil with some water in a spray bottle and spray the affected areas. To make mixing the tea tree with water easier, add a few drops of a soap dish.

You can eliminate bedbugs by spraying a few drops around your bed, closets, or any other location where they are likely to be found.

Do Bed Bugs Come Out In Light?

Bedbugs detest light and will not come out if the lights are turned on unless they are starving. They are nocturnal, meaning they prefer to hunt for food at night. However, leaving your lights turned on will not keep them away; they still need to eat.

Bedbugs will still emerge in daylight if your sleeping routine changes. They will come out to feed during the day if you work at night and sleep during the day.

When the infection becomes very large, there will be a lot of competition for hosts. Those who were unable to obtain a meal throughout the night will return during the day to try their luck.

Can Bed Bugs Kill You?

The worst a bedbug can do is give you a few itchy bites, but they won’t kill you. You might miss a few hours of sleep because you’re frightened that the bedbugs will bite you as you sleep. Most people are afraid of bedbugs, but this does not mean they will kill you.

When a person has pre-existing ailments, bedbug bites might well be dangerous. Bed bug bites only cause significant health problems in a small percentage of cases. While bedbug bites are unlikely to kill you, they can make you sick. If you do not get treatment, your condition could worsen and even become fatal.

Sepsis is one of the diseases that might be lethal due to bedbug bites. Failure to treat bedbug bites causes sepsis. If not treated quickly, it can lead to septic shock, which can be deadly.

People who have strong allergic reactions to bedbug bites are also at risk, especially if the reaction is severe. Don’t take allergic reactions lightly; they can quickly turn into anaphylaxis, a life-threatening reaction.


Don’t panic if you discover a bedbug infestation in your home. Bedbugs, as annoying as they are, can be eliminated. Eucalyptus oil is one of the most effective natural ways to get rid of that infestation.

You can use other essential oils such as lavender, lemongrass, peppermint, tea tree, and lemon. Cleaning detergents and products can be infused with essential oils to help in killing bedbugs.

Unless you have underlying health issues, bedbug bites will not kill you. While a single sting will not cause severe injury, a series of stings may not leave you so lucky.
