10 Essential Oils For Bug Bites That Give Fast Relief

When it comes to essential oils for bug bites, picking the ones that actually relieve the discomfort, irritation, swelling, pain, and redness is important. Though essential oils are plant-derived, natural, and pure, they are potent and not all work the same in treating a condition.

On that note, let’s understand what essential oils truly help treat bug bites. But before that, here is a little important information that you should know.


In practice, the term “bug” generally addresses tiny creatures with legs. These crawling creatures are often confused with each other.Bugs and insects share the same Phylum “Arthropods” and Class “Insecta” in the Taxonomical Classification of Animals.

Arthropods are joint-footed animals with an external skeletal system. The term “Insecta” refers to the body segmentation seen in the creatures. Both Bugs and Insects belong to this category.

So this means, bugs are a specific type of insects, but all insects are not bugs. A true bug has straw-shaped mouth called stylet, hardened forewings and one set of wings.

There are about 75000 species of Bugs. The familiar ones include Leaf-hoppers, Water Bugs, Stink Bugs, Bed Bugs, Cicadas, Aphids, Lice, and Boxelder bugs. They belong to the Order “Hemiptera” meaning “Semi-developed wing.” Since the wings are half developed, they are partly hard and partly membranous.

Bugs use “Stylet” to suck plant juices or blood. 

All bugs carry a chemical, which is a mild venom. However, a group of assassin bugs found in tropical regions are highly venomous and transmit Chagas disease, which may even be fatal. Few of them are intentional biters and others bite when threatened.

Assassin Bugs: These belong to the family Reduviidae. They paralyze the prey using toxins. They do not eat the whole prey. Instead, the fluid inside the prey’s body is sucked through stylet. Few of the assassin bugs are ambush bugs, wheel bug and cone-nosed bug.

How does your body react to a bug bite?

Your immune system responds rapidly to the venom injected by the bite or sting. The immune system pushes histamine and other inflammatory mediators to that affected site. This causes inflammation. The immediate response thus includes redness and swelling at the site, while itchiness occurs after some time.

Symptoms Of Bug Bites

The symptoms vary with the type of venom injected by the bug.

  • Mild venom attack may cause redness, rash, swelling, itching, pain in the affected area or tingling
  • Severe immediate reactions may include fever, vomiting, breathing difficulty, loss of consciousness.
  • If you undergo any of the severe reactions or shortness of breath, do visit a doctor immediately.

Essential oils are used since ancient times for various purposes. They aid in curing bug bites because application of oil on the affected site prevents us from itching and soothes the pain. Moreover, essential oils have compounds that are highly anti-inflammatory, analgesic, antinociceptive and antiseptic.

1. Lemongrass Oil

essential oils for bug bites

Lemongrass is an aromatic perennial herb widely distributed in tropical and sub-tropical regions. Cymbopogon citratus and Cymbopogon flexuosus are commonly known as Lemongrass.

Cymbopogon flexuosus are significant in Perfume industries while Cymbopogon citratus is known for its aromatic as well as medicinal properties.

A thin, amber or light yellow colored consistency and a strong lemony scent characterize Lemongrass oil (1). The oil is obtained through Steam distillation of dried leaves.  The essential oil thus obtained is purified with anhydrous Sodium sulphate (2).

The oil contains 75 to 85% Citral. The Citral content determines the quality of lemongrass oil. There are about 23 chemical components found in the oil. Of those, the major ones are geranial, neral, β-myrcene. Geranyl acetate and isopulegol are found in minor quantities yet significant.

According to the researchers, Lemongrass Oil inhibits the skin inflammatory response in animals. Geranial and neral are the primary compounds responsible for the oil’s anti-inflammatory and anti-nociceptive properties. The oil also possesses anti-allergic property because of the presence of Z-asarone.

The antinociceptive property soothes the pain caused due to bug bite and sting. Also, allergies and inflammation reduce significantly with the application of Lemongrass oil on the affected area. However, you should make sure you follow a correct method of application.


  • Dilute 2-3 drops of lemongrass oil with a tablespoon of coconut oil. Apply it on the infected area twice a day to prevent itching.
  • In case of acute pain, you can also apply the same oil blend on the skin and leave it overnight to soothe pain and irritation.


  • Not safe for children under 6 and pregnant women.
  • Conduct a patch test before use.
  • People with estrogen-dependent cancer should avoid Lemongrass oil.

2. Basil Oil

Basil (Ocimum sanctum) an indigenous Indian annual herb is often revered as an “elixir of life” for its healing properties (3). They are treated as ‘the Mother Medicine of Nature’ since ancient times due to their power to cure various ailments.

Sweet, herbaceous, slightly camphorous odor, thin consistency and a clear liquid characterize Basil essential oil.

Researchers have found about 25 active compounds in the Basil oil, of which, the significant constituents are linalool, citral, 1,8-cineole, methyl chavicol, camphor, methyl cinnamate, thymol, methyl eugenol, eugenol, elemicin, and methyl isoeugenol (4).

Linoleic acid present in the oil blocks the mechanism that is responsible for causing inflammation in the body. This makes it an anti-inflammatory, antinociceptive and analgesic.

Basil in its crude extract contains compounds like Civsilineol, Civsimavatine, Isothymonin, Apigenin, Rosavinic acid and Eugenol which are responsible for its anti-inflammatory properties (5).

Basil oil prevents immune reactions thus reducing the redness and swelling on the inflamed areas.


  • Blend 2-3 drops of basil oil with a teaspoon of coconut oil and apply it on the skin twice daily.
  • To reduce pain, dilute the Basil oil with water and use as a cold compress.
  • Massage the infected place using a cotton ball dipped in the oil blend.


  • Pregnant and lactating mothers should not use Basil Oil.
  • Basil oil is not recommended for internal use.
  • People who have epilepsy and cancer should avoid Basil oil

Geranium oil is extracted from Pelargonium species. The plants are appreciated for their vivid pink blooms. Oil is obtained from the leaves and stems of the plant through the steam distillation process. The leaves have various applications like flavouring, insect repellents, perfume and pharmaceuticals. Yellowish-green liquid and strong lemon-rose odour characterise Geranium oil.

The oil has about 42 different compounds of which the prominent ones are Linalool, Citronellol, Geraniol, 6-Octen-1-ol, 3,7-dimethyl-, formate, and Selinene (9).

Citronellol and Geraniol are considered as the major compounds in Geranium oil and are responsible for anti-inflammatory properties. Research evidence in mice shows that Geranium oil inhibits one or more signalling pathways in the effects caused by inflammatory mediators thus reducing the inflammation (10).

Geranium oil is highly recommended to treat bug bite. Lice is one of the most commonly occurring problems among people of any age. Lice, the minuscule creatures are pesky. Lice infestation quickly spreads and cause itching and tiny red bites on the scalp.  Germanium oil is considered one of the best method to remove the head lice.

Tea tree oil is one of the popular and efficient essential oils for bug bites. Melaleuca alternifolia, the source of Tea tree oil is a native to Queensland and Australia. Oil is extracted from dried leaves and terminal branches through the steam distillation method.

Research shows that Tea tree oil has about 100 compounds of which terpinen-4-ol and α-terpineol, are significant components of the oil. Other significant compounds are α-pinene, β-pinene, 1,8-cineole and linalool. Teat tree oil is anti-bacterial, anti-viral and anti-inflammatory.

There is evidence that the Tea tree oil affects various immune responses. Terpinen-4-ol, α-terpineol, and 1,8-cineole are found to be the main components responsible for the anti-inflammatory property of Tea tree oil (11).

In an evidence-based study, it was inferred that 1% concentration of tea tree oil was effective against head lice with 100% mortality in just 30 minutes (12).


  • To remove head lice, apply 20 – 40 drops of tea tree oil diluted with coconut oil or apply it on the scalp. Leave it for around 40 minutes and then shampoo the hair. Do this until lice are entirely eradicated.
  • Dilute 4 – 6 drops of tea tree oil in water and apply on the inflamed skin to reduce inflammation.


  • Tea tree oil is strictly not for ingestion.
  • Skin irritation if caused should be addressed immediately.

6. Peppermint Oil

Peppermint oil is extracted from Mentha x Piperita, a cross between watermint and spearmint. It is a watery pale yellow with crisp methanol fragrance. Peppermint is known for its antiseptic, analgesic, antiphlogistic properties.

51 compounds are identified by the chromatographic analysis of peppermint oil purified after hydrodistillation of peppermint leaves. Methanol, menthone and menthyl acetate are found predominantly (13).

Neomenthol, pulegone, cineol and caryophyllene are other significant compounds present. However, the active components vary with the region where peppermint is grown, harvest season, temperature, radiation and humidity.

Peppermint inhibits the inflammatory mediators thus reducing further inflammation. Spathulenol, cadinene, caryophyllene and caryophyllene oxide are the compounds responsible for the anti-inflammatory property of the oil (14).

The inhibition of inflammatory mediators is crucial in treating bug bites. Peppermint oil is one of the best choices.

Thymus vulgaris, a perennial herb is the source of Thyme oil. Thyme is one of the oldest medicinal plants. Thyme has a wide range of applications in Pharmaceutical and cosmetic fields as well.

Thymol, carvacrol, γ-terpinene and p-cymene are significant components of thyme oil.  The other minor components present are geraniol, linalool, gamma-terpineol, carvacrol, thymol and terpinen-4-ol (15).

Thyme oils are known for its antimicrobial, antitumor, antimutagenic, antigenotoxic, analgesic, anti-inflammatory, angiogenic, antiparasitic, antiplatelet, antihepatotoxic, and hepatoprotective properties

When a bug bites you, your immune system responds immediately to it. This causes inflammation. Carvacrol and thymol present in Thyme oil inhibit the enzyme responsible for inflammation thus preventing you from further inflammation (16).

In addition to anti-inflammatory properties, Thyme oil exhibits anti-lifestyle related disease properties (17).


  • Blend 6 – 10 drops of Thyme oil with 2 or 3 drops of Lavender oil and apply it on the infected skin to heal.
  • Add 10 drops of thyme oil with water and bath in it. This calms the body reducing itchiness and pain.


  • Pregnant women should avoid this.
  • Sometimes may cause skin irritation.

8. Eucalyptus Oil

essential oils for bug bites

Eucalyptus oil is derived from the distillation of dried eucalyptus leaves from Eucalyptus radiate, E. globulus and so on. Research says that there are about 700 species of Eucalyptus trees. Eucalyptus oil is registered insecticide and miticide (18).

Eucalyptus oil is used since ancient times to treat respiratory diseases, allergies, asthma, heal wounds and also as an insect repellent. They are known for their antiseptic, antimicrobial, antiviral, antibacterial and antifungal properties.

Eucalyptus is widely used to ease pain and inflammation.

Studies show that α-pinene, 1,8-cineol and pinocarveol-trans are significant components found in Eucalyptus oil. There are about 100 chemical compounds found in it of which 1,8-cineol is the major one (19).

When your body gets exposed or bitten by a Bug, your immune system considers it as an allergen and starts reacting to it. The mechanisms of your immune system deploy inflammatory mediators. 1,8-cineol and α-pinene present in the Eucalyptus oil inhibits these inflammatory mediators preventing further inflammation (20).


  • Blend 4-6 drops of Eucalyptus oil with a tablespoon of almond oil or coconut oil. Apply the concoction of the skin. Almond oil facilitates fast absorption and relieves pain immediately.
  • Using a few drops of Eucalyptus oil in steam therapy calms down the entire body.
  • You can also use it in warm water to take a bath.

The primary and active components of Chamomile oil are α-bisabolol oxide A & B, α-bisabolol, sesquiterpenes, chamazulene, umbelliferone, coumarins, flavonoids, apigenin, luteolin, spiroethers, quercetin, and en-yn dicycloether (21).

Components such as tannins, choline, anthemic acid, phytoestrogens, and polysaccharides are minor yet significant.

Chamazulene is produced during the distillation process and, gives the oil its blue colour. It is about 5% of the essential oil.

Bisabolol comprises 50% of German Chamomile oil. The flavonoids apigenin and luteolin are responsible for anti-inflammatory, carminative, and antispasmodic properties (22).

Chamomile oil is promising in treating bug bites and inflamed skin.


  • Blend a few drops of Chamomile oil with peppermint oil or lavender oil and apply it on the skin to reduce inflammation. Repeat it every night until the problem resolves.
  • Mix 2-3 drops of Chamomile oil and lavender oil with water. Use this as a moisturizer to prevent skin irritation.
  • Dilute it with water and use as a cold compress in case of severe pain.


  • Pregnant women should avoid this.

10. Rosemary Oil

natural treatment for bug bites

Rosemary (Rosmarinus officinalis) belongs to the mint family of Lamiaceae and native to Mediterranean regions. A thin clear liquid and mint-like herbaceous fragrance characterise Rosemary oil.

It is also one of the most popular oil with limitless applications. Rosemary oil possesses antispasmodic, analgesic, antirheumatic, carminative, cholagogue, diuretic, expectorant, antiepileptic, anti-inflammatory and peripheral antinociceptive activity (23).

Carnosic acid, carnosol and rosmarinic acid present in the oil are responsible for antioxidant and anti-inflammatory properties. These compounds reduce the number of White Blood cells at the site of inflammation, which results in anti-inflammatory response. The oil when applied inhibits inflammatory mediators. The anti-inflammatory activity of Rosemary is higher than indomethacin, a common anti-inflammatory drug (24).


  • Rosemary oil blends well with peppermint oil, thyme oil, tea tree oil and camphor oil.
