Eucalyptus Oil For Bed Bugs

Can You Use Eucalyptus Oil For Bed Bugs?

Eucalyptus oil is an excellent way of controlling bed bug infestations right at the start. If you are tackling a severe bed bug infestation, I suggest using more powerful methods.

Insecticides are the only guaranteed way of treating a severe infestation, and even when using these, it still takes a while!

Eucalyptus oil is a scent that bed bugs do not like and can be used for mild infestations or can even be used to keep them away from your bed.

If you have a severe infestation, you can add other natural ways to the process. I would follow this process if you are looking for a natural way of getting rid of bedbugs:

  • Seal any wall holes that you can use to nest bed bugs. Use caulk.
  • Wash bedclothes in a hot wash. If you live in a hot climate, you can put the bedclothes in a plastic bag and leave them in direct sunlight for 1 day before washing them. After washing them, iron them too. Heat kills bed bugs!
  • Thoroughly clean your bed with a steam cleaner.
  • Spray eucalyptus/tea tree oil over your bed.
  • Repeat until the infestation is gone.

Battling a bed bug infestation takes a long time. It is not something that you can complete in one day or night. You have to keep going until they have gone. Take away the nests and clean areas where they like to nest, and the numbers will begin to go down.

Once the numbers are manageable, you can use other methods with eucalyptus oil, such as one of the following.

How To Use Eucalyptus Oil For Bed Bugs Infographic

Homemade Spray 1


  • 20 drops of eucalyptus oil
  • 10 drops of tea tree oil
  • 1 cup of water

Add this mixture into a spray bottle, and you have made a natural repellent and killer for bed bugs!

Not only does it have eucalyptus oil in it, but it also has a potent tea tree oil! Bed bugs will really struggle against this mixture.

Homemade Spray 2

  • 30 drops of eucalyptus oil
  • 1 cup of water

Add this mixture into a spray bottle, and you have made a natural repellent and killer for bed bugs!

The difference between this mixture and the homemade spray 1 (above) is that it doesn’t have tea tree oil.

Tea tree oil makes the mixture stronger and will give you more success in attacking the bed bugs.

Oil Burner

You will need to have at least 1 oil burner for this, and although it is not as effective as the spray, it is also a great option to deter and get rid of bed bugs naturally.

All you need to do it set up your oil burner with a little water, and drop in 5 or 6 droplets of eucalyptus oil before lighting the candle.

Make sure the oil burners are near the bed and other areas where you have seen bed bugs.

*Do not leave a candle alight while you are asleep; you should watch the candle until it is no longer alight*

Cleaning Equipment

As an additional cleaning product, you can add eucalyptus oil to other sprays or detergents to increase the chances of killing these pests.

You can also apply the essential oil to other cleaning equipment, such as a cloth or a sponge.


This is very similar to the oil burner idea. To work effectively, you will need to have the diffuser close to the bed and other areas where you have seen bed bugs.

It is a great deterrent, but you will also need to make the sprays or add to cleaning equipment to get rid of them first.

As I have already mentioned, you need to perform additional tasks to attack a severe infestation. Start by killing the bed bugs with heat. I use a hot wash, followed by running an iron over the sheets. I also steam clean the entire bed and fill any holes in the wall that you can use to nest for bed bugs.

You have to attack these problems from multiple angles!

Good luck!
