Does Aloe Vera Repel Mosquitoes? Science Says Only Slightly

By James Wilson · January 23, 2026

Does Aloe Vera Repel Mosquitoes? The Direct Answer

Yes, aloe vera has mild mosquito-repelling properties due to its natural compounds like saponins and anthraquinones, but it is not as effective as commercial repellents containing DEET or picaridin. While aloe vera can soothe bites and provide light protection, it should be combined with proven repellents for reliable mosquito defense.

Why People Believe Aloe Vera Repels Mosquitoes

Aloe vera is widely associated with skin health and natural remedies, leading many to assume it also deters mosquitoes. This belief stems from:

Its strong, bitter scent that may discourage some insects
Natural bioactive compounds such as aloin and emodin, which have shown insecticidal effects in lab studies
Traditional use in tropical regions where both mosquitoes and aloe are common
Post-bite soothing effect, creating the impression of prevention

Scientific Evidence Behind Aloe Vera and Insect Repellency

While limited, some research supports aloe vera's role in pest management:

A 2014 study found aloe vera gel mixed with other plant oils reduced mosquito landings by up to 70% for 4 hours 1
In vitro tests show aloe extracts disrupt mosquito sensory receptors 2
No standalone clinical trial proves pure aloe vera gel repels mosquitoes effectively over time

How Aloe Vera Compares to Proven Mosquito Repellents

To understand aloe vera’s real-world effectiveness, we compare key repellents using duration, active ingredients, and efficacy data.

Repellent Type	Active Ingredient	Protection Duration	Efficacy (%) Against Mosquitoes
DEET (25%)	N,N-Diethyl-meta-toluamide	Up to 10 hours	99%
Picaridin (20%)	KBR 3023	8 hours	98%
Oil of Lemon Eucalyptus	PMD (para-menthane-3,8-diol)	6 hours	95%
Aloe Vera + Essential Oils	Saponins, Aloin	1–2 hours	60–70%
Pure Aloe Vera Gel	Aloin, Polysaccharides	Less than 30 minutes	~20%

Table data source:3, 1, 4

The data shows that while aloe vera-based formulations offer moderate short-term protection when blended with essential oils, they fall significantly short of synthetic or EPA-approved natural repellents. Pure aloe vera gel provides minimal repellency and is unsuitable as a primary defense.

Using Aloe Vera Effectively: Tips and Blends

If you prefer natural solutions, enhance aloe vera’s repellent power through strategic blending:

Mix with essential oils: Combine aloe vera gel with citronella, eucalyptus, or lemongrass oil (10 drops per ounce of gel) for improved results
Apply after sunscreen: Use aloe only after sun protection, never as a substitute
Reapply every 1–2 hours: Due to rapid evaporation and degradation of natural compounds
Test on small skin areas first: Some individuals may experience irritation from concentrated aloe or oil mixtures

Limitations and Safety Considerations

Despite its popularity, relying solely on aloe vera poses risks:

Lack of standardized concentration in commercial gels
No EPA registration or regulatory oversight for repellency claims
Potential allergic reactions, especially in people sensitive to Liliaceae plants
Inadequate protection in high-risk areas for diseases like dengue, Zika, or malaria

Frequently Asked Questions About Aloe Vera and Mosquito Repellency

Can aloe vera keep mosquitoes away naturally?

Aloe vera has mild natural repellent properties due to compounds like saponins and aloin, but it does not provide strong or long-lasting protection. It works best when combined with known repellent oils such as citronella or eucalyptus.

Is pure aloe vera gel effective against mosquito bites?

Pure aloe vera gel offers little to no mosquito repellency. However, it is excellent for soothing itching and inflammation after bites due to its anti-inflammatory and moisturizing properties.

How can I make a natural mosquito repellent with aloe vera?

Mix 1 ounce of aloe vera gel with 10–15 drops of essential oils like lemon eucalyptus, lavender, or peppermint. Store in a cool place and reapply every 1–2 hours for best results.

Does aloe vera attract any insects?

No evidence suggests aloe vera attracts mosquitoes or other biting insects. However, its sugary sap may attract ants or non-biting pests if spilled or over-applied outdoors.

Are there any scientific studies proving aloe vera repels mosquitoes?

Some laboratory and field studies show aloe vera enhances the efficacy of plant-based repellent blends, reducing mosquito landings by up to 70% for short durations. However, no major health authority recognizes pure aloe vera as a standalone repellent 1.
