When planning an exciting trip abroad – whether it’s a tropical beach escape, a safari adventure, or a business visit to warmer climates – insect protection should be at the top of your checklist. Many destinations around the world are home to insects that can carry serious diseases, including mosquitoes that spread malaria, dengue fever, and Zika virus, as well as ticks and sandflies that can transmit other infections. Choosing the right insect repellent and knowing how to use it effectively can make a huge difference to your travel health and comfort.
At Brixton Travel Clinic, we provide expert advice on protecting yourself from insect-borne diseases and offer a wide range of travel vaccinations to ensure you’re fully prepared for your journey.
Why Insect Protection Matters When Travelling
Insects are more than just an inconvenience when travelling. In many parts of the world, they pose a significant health risk. Mosquitoes, for example, are responsible for transmitting several potentially serious illnesses, including:
-
Malaria – found in parts of Africa, Asia, and South America
-
Dengue fever – common in tropical and subtropical regions
-
Zika virus – reported in some parts of South America, Central America, and the Caribbean
- Yellow fever – prevalent in parts of Africa and South America
These diseases can cause severe illness and, in some cases, may be life-threatening. Using an effective insect repellent alongside other protective measures significantly reduces your risk.
Choosing the Right Insect Repellent
Not all insect repellents are created equal, and selecting the right one for your destination is essential. The effectiveness of a repellent depends on its active ingredient, concentration, and duration of protection.
The most widely recommended active ingredients include:
-
DEET (N,N-diethyl-meta-toluamide) – Considered one of the most effective repellents, DEET provides long-lasting protection against a wide range of insects. A concentration of 20–50% is generally recommended for high-risk areas.
-
Picaridin (also known as icaridin) – A good alternative to DEET, picaridin is effective, odourless, and less likely to irritate the skin.
-
Oil of Lemon Eucalyptus (OLE) – A natural option suitable for areas with lower risk, though protection time may be shorter than DEET-based products.
- IR3535 – Often used in sensitive-skin formulations, offering good protection in some regions.
At Brixton Travel Clinic, we can advise on the most suitable insect repellent based on your destination, duration of stay, and personal needs.
Tips for Effective Use of Insect Repellent
Even the best repellent won’t work if it’s not applied properly. To get the maximum protection, keep the following tips in mind:
-
Apply generously and evenly to all exposed skin, ensuring full coverage.
-
Reapply as directed, especially after swimming, sweating, or towel-drying.
-
Combine repellent with sunscreen carefully – if you’re using both, apply sunscreen first, allow it to absorb, and then apply the repellent.
-
Use repellents on clothing if needed – some products are suitable for spraying on fabrics, adding another layer of defence.
- Avoid applying near eyes or mouth, and wash hands thoroughly after application.
Other Protective Measures Against Insect Bites
While repellents are highly effective, using them alongside other protective measures provides even better protection. Brixton Travel Clinic recommends:
-
Wearing long sleeves and trousers, especially in the evenings when mosquitoes are most active.
-
Sleeping under insecticide-treated bed nets in areas where malaria and other mosquito-borne diseases are common.
-
Choosing accommodation with screened windows and doors to minimise exposure.
-
Using plug-in insecticide vaporisers or coils where appropriate.
Combining repellents with these extra steps helps create a strong barrier against insect bites and reduces your risk of infection.
Insect-Borne Disease Vaccinations and Travel Health Advice
Vaccination also plays an important role in protecting against some insect-borne illnesses. For example, yellow fever vaccination is required for travel to certain countries and strongly recommended in many high-risk areas.
At Brixton Travel Clinic, our expert team can advise you on which travel vaccinations you need based on your destination and planned activities. Some common vaccinations related to insect-borne diseases include:
-
Yellow fever – essential for many parts of Africa and South America
-
Japanese encephalitis – recommended for extended stays in parts of Asia
-
Tick-borne encephalitis – relevant for certain parts of Europe and Asia
We also provide comprehensive malaria prevention advice and can prescribe antimalarial medication where necessary.
