Travelling abroad can be exciting, but protecting yourself from insect bites should always be a priority. Mosquitoes, ticks, and other biting insects are not only uncomfortable but can also transmit serious diseases such as malaria, dengue fever, and Zika virus. One of the most effective ways to prevent bites is through the use of DEET insect repellent. At Market Harborough Pharmacy, we provide expert advice on travel health essentials, including insect repellents, to help you stay safe wherever your journey takes you.
What Is DEET?
DEET (N,N-diethyl-meta-toluamide) is a widely used active ingredient in many insect repellents. First developed by the US Army in the 1940s, it has become the gold standard for bite prevention worldwide. DEET works by interfering with the sensory receptors of insects, making it difficult for them to detect humans. This means mosquitoes, ticks, and other insects are far less likely to land and bite when DEET repellent is applied properly.
Why Use DEET Insect Repellent?
There are many types of insect repellents available, but DEET has stood the test of time due to its proven effectiveness. It provides strong protection in a wide range of environments, from tropical regions to temperate climates. Whether you are travelling for work, leisure, or adventure, DEET can help prevent insect-borne illnesses that can disrupt your trip and impact your health.
Benefits of DEET Repellent
- –> Highly effective against mosquitoes, ticks, and other biting insects
- –> Long-lasting protection, depending on concentration
- –> Suitable for use in areas with high risk of insect-borne diseases
- –> Recommended by health organisations for travellers
Choosing the Right Strength of DEET
DEET repellents are available in different concentrations, typically ranging from 20% to 50%. The percentage you choose will depend on your destination, the risk of disease, and the duration of protection you need.
- –> 20% DEET: Provides around 2–3 hours of protection. Suitable for lower-risk areas or short outdoor activities.
- –> 30% DEET: Offers longer protection, up to 6 hours. Ideal for moderate-risk regions and daily use.
- –> 50% DEET: Provides up to 12 hours of protection. Recommended for high-risk regions with diseases such as malaria.
For most travellers, a concentration between 30% and 50% is recommended, especially in tropical or subtropical regions. Our team at Market Harborough Pharmacy can help you choose the most appropriate option for your trip.
How to Use DEET Safely
DEET is safe for most people when used correctly. To maximise effectiveness and minimise risks, follow these guidelines:
- –> Apply repellent evenly to all exposed skin
- –> Avoid applying under clothing
- –> Do not apply to broken or irritated skin
- –> Wash off repellent with soap and water after returning indoors
- –> For children, use lower concentrations and avoid hands, eyes, and mouth
When using sunscreen and DEET together, always apply sunscreen first, allow it to absorb, and then apply the insect repellent.
Alternatives and Complementary Protection
While DEET is highly effective, combining it with other protective measures can enhance your safety. Alternatives such as picaridin or oil of lemon eucalyptus can provide protection, though often for shorter periods. In high-risk regions, it is best to use DEET as your primary repellent.
Additional measures to reduce insect bites include:
- –> Wearing long sleeves and trousers, especially at dawn and dusk
- –> Sleeping under insecticide-treated mosquito nets
- –> Staying in accommodations with screened windows or air conditioning
- –> Using permethrin-treated clothing for added protection
