When travelling abroad or spending time outdoors, insect bites can be more than just an irritation—they can also pose serious health risks. Using an effective insect repellent is one of the best ways to protect yourself from bites that can transmit diseases such as malaria, dengue fever, and Zika virus. At Townhead Pharmacy in Kilwinning, we provide expert advice on choosing and using DEET insect repellent to help you stay safe wherever you travel.
What Is DEET?
DEET (N,N-diethyl-meta-toluamide) is a highly effective ingredient used in many insect repellents worldwide. Originally developed for the U.S. Army in the 1940s, it remains one of the most trusted and tested solutions for preventing mosquito and other insect bites. DEET works by interfering with insects’ ability to detect human scent, making you less likely to be targeted by biting insects.
Whether you’re heading to a tropical destination or spending summer evenings outdoors in the UK, DEET can offer reliable, long-lasting protection.
How Does DEET Insect Repellent Work?
Insects such as mosquitoes and ticks are attracted to the carbon dioxide and body odour humans naturally produce. DEET works by masking these scents, effectively confusing insects and preventing them from locating you. It doesn’t kill insects—it simply keeps them at a safe distance, reducing the chance of bites.
Benefits of DEET-Based Repellents
–> Proven effectiveness: Decades of research confirm DEET’s ability to repel mosquitoes, ticks, and other biting insects.
–> Long-lasting protection: Higher concentrations of DEET can provide up to 8–10 hours of defence.
–> Suitable for travel: Ideal for regions with mosquito-borne diseases such as malaria, yellow fever, or Zika.
–> Versatile use: Available in sprays, lotions, and wipes for easy application.
Choosing the Right Strength
DEET repellents come in various concentrations, typically ranging from 10% to 50%. The right strength depends on your environment, activity level, and how long you need protection.
–> 10–20% DEET: Suitable for everyday outdoor use in low-risk areas. Offers around 2–4 hours of protection.
–> 30–40% DEET: Recommended for travellers to areas with moderate mosquito activity. Provides 6–8 hours of coverage.
–> 50% DEET: Ideal for high-risk destinations where mosquito-borne diseases are prevalent. Lasts up to 10 hours.
It’s important to note that higher concentrations do not make the repellent more effective—only longer lasting. Always choose the concentration best suited to your needs and follow usage guidelines carefully.
How to Apply DEET Insect Repellent Safely
Using DEET correctly ensures maximum protection while minimising the risk of irritation or product waste. Here’s how to use it safely:
–> Apply a thin, even layer to all exposed skin areas.
–> Use after applying sunscreen—DEET can reduce the effectiveness of sun cream if used first.
–> Avoid spraying directly onto the face; apply to your hands first, then rub gently onto the face and neck.
–> Do not apply under clothing or to broken or irritated skin.
–> Wash skin with soap and water once protection is no longer needed.
–> Keep out of reach of young children and avoid overuse.
When used correctly, DEET repellents are safe for adults and children over two months old. For infants and those with sensitive skin, your pharmacist can recommend appropriate formulations.
Alternatives to DEET
While DEET is the gold standard, other active ingredients can also provide effective protection:
–> Picaridin (also known as Icaridin): Offers similar protection to DEET with a lighter feel and less odour.
–> Citriodiol: A natural oil derived from lemon eucalyptus, suitable for short-term use or those preferring plant-based options.
However, for travel to regions where malaria and other vector-borne diseases are common, DEET remains the most recommended choice for reliable protection.
