If you want to stop the bed bug bites and find out if peppermint oil repels bed bugs, please read on.

What are bed bugs and what do they look like?



Bed bugs are flat, oval-shaped insects, around 5-7 mm in length. A bed bug is reddish-brown and will appear redder after a blood meal. They are slow at reproducing, laying one to five eggs a day, 250 in their lifetime, compared to a fly who lays over 500 eggs in 4 days.

They like to feed on human blood if available, but if not they will bite other mammals. Bites occur mainly at night, as bed bugs are nocturnal. However, if they need a meal they will bite during the day.

When a bed bug bites, it releases an anesthetic and anticoagulant into the bloodstream. The anticoagulant allows blood to flow and the anesthetic is released so you cannot feel the biting.

They do not have wings so they cannot fly. However, they can move very quickly.

Does peppermint oil repel bed bugs?

One of the best essential oils to use for bed bugs is peppermint oil. Peppermint oil is very versatile and works as a repellent and a contact insecticide. Peppermint oil comes from the middle east and is a mix of water, mint, and spearmint.

Peppermint oil is natural and great for a bed bug problem. Peppermint essential oil is also good as a repellent for cockroaches, and spiders will stay away.

Peppermint essential oil contains menthol, giving a cooling feeling.

To use peppermint oil, it needs to be diluted with a carrier oil. Because of its strength it can irritate the skin and eyes. The oil on contact with the skin will leave a burning feeling. For a bed bug, contact with peppermint oil is agonizing death.

A carrier oil can be coconut, jojoba, olive oil, or almond.

Use peppermint oil mixed with water – 10 drops of oil to 30 ml of water – and use a spray to apply to bed sheets and mattress.

Do not use too much peppermint oil in a child’s room, as it could affect sensitive skin.

Peppermint essential oil is also great at keeping bees, ants, and mosquitoes away.

Peppermint oil can also be mixed with other essential oils and used for aching muscles.

How to make Thieves oil

Does Tea tree oil repel bed bugs or kill bed bugs?

Another one of the best essential oils to use is tea tree oil. The tea tree is from the Melaleuca Alternifolia plant native to Australia.

It is an essential oil that is natural and is known for its antibacterial properties. You can use a spray bottle and spray it over your bed and furniture to repel bed bugs.

The oil is also used to treat acne and bites.

How does it work for bed bug control?

The oil is a natural repellent and insecticide, and it will kill insects like mosquitoes, ants, lice, parasites, and other biting and stinging insects.

Bed bugs do not like the smell of it. The oil can damage their exoskeleton, causing suffocation.

Bed bugs can only die from the oil by direct contact, and it must be diluted as it is not good for humans.

Some people can be allergic to tea tree oil, so you need to be careful where you spray it. Also be aware it may cause staining on some items.

The oil can be used as a treatment for bites, but do a patch test first. Place a tiny amount on the back of your wrist and leave for 24 hours. If there is no irritation or rash on the skin, it is a safe oil for bed bug bites.

The oil acts as a temporary bed bug repellent, like rubbing alcohol, on a small infestation. It must be diluted before use.

Will Lavender oil keep bed bugs away?

This oil is one of the safest oils to use. Lavender essential oil is natural with a nice scent, and bed bugs repel away from it especially if it is pure oil. Add 6-10 drops in an atomizer and the bed bugs will run.

Atomizers are readily available to buy, so get some and place a few around the house and allow the strong scent to work all around to keep bed bugs at bay. Most people love the smell of lavender. However, with its strong scent, bed bugs and many other insects and household pests will soon disappear.

Is Eucalyptus oil effective against bed bugs?

What about other essential oils that act as a repellent?

With clove oil, bed bugs find the strong scent hard to suffer, so it makes a good repellent. This oil contains eugenol, which is toxic to all insects and therefore will provide good pest control.

How to use it: Mix 10 drops of oil with 30 ml of water into a bottle and spray on bedding, sheets, and on the mattress to see off bed bugs.

Neem oil

Can Diatomaceous earth kill a bed bug?

Yes, it will kill bed bugs. It is a very good form of pest control and commonly used.

Diatomaceous earth is a naturally occurring white crystalline powder, made of fossilized algae and other fossilized water plants.

It is non-toxic, but not to bed bugs and other insects. Its silica base and rough crystals penetrate the waxy exoskeleton of an insect, drying their bodies out, which kills bed bugs.

Apply along the seams of your mattress, to the bed frame, and other furniture.

Vacuum after a couple of days and reapply straight after vacuuming.

Does rubbing alcohol get rid of bed bugs?

Steam and vacuum cleaning

Buy a steam cleaner and a good vacuum cleaner, ones that can clean in tight spots and crevices. You can steam clean your mattress regularly and clean various other furniture with a steam cleaner. Always follow manufacturers advice. Vacuum regularly to remove bed bugs and eggs, put contents in a sealed bag, and throw them away.carpet-steam-cleaning
