Why does insect protection matter?

Biting insects are more than just a nuisance. In many countries, mosquitoes carry diseases such as malaria, dengue fever and Zika. Even when disease isn't a risk, getting swarmed by midges in the Scottish Highlands isn't many people's idea of fun. Effective protection comes down to a combination of repellents, nets, clothing and accessories. We will break down these options and explain the benefits of each, whether you are off travelling or having an adventure closer to home.

What is the best insect repellent?

DEET

DEET is a highly effective active ingredient used in insect repellents. It has been used since the 1940s and offers reliable protection again mosquitos, ticks, fleas and biting flies. It is essential to use it in areas where malaria and other diseases are present. Rather than killing, DEET binds to insects' sensory receptors, making it difficult for them to detect human scents.

DEET is considered safe for pregnant and breastfeeding people and babies over 2 months old. When applying to children, you should apply it to your hands first and then gently rub it onto the child.

It is important to note that DEET is a strong solvent and can melt or damage synthetic fabrics like plastics. Contact with eyes can cause severe stinging, and DEET can irritate sensitive skin.

Higher concentrations of DEET do not make it work better, just last longer.

DEET concentration explained:

  • 20–50% DEET: general outdoor use, suitable for low-risk countries, reapply every 6–8 hours 

  • 20–40% DEET: endurance formulas, suitable for high-risk areas (Sub-Saharan Africa, South America, Asia), lasts 10–12 hours, suitable for children 2+ 

  • 50–95% DEET: maximum protection in high-risk areas, not suitable for children under 6, lasts 8–10 hours. You'll find this in products like Lifesystems Expedition MAX.

Alternatives to DEET

Some people may choose not to use DEET due to its smell and feel. It may not be suitable if you have sensitive skin, and some people prefer natural or more gentle alternatives. However, if you are travelling, it is important to note that using DEET-based insect repellent is highly recommended in malaria-risk countries, and alternative repellents may not offer adequate protection.

Image of Permethrin

Permethrin

This is a type of pyrethroid, a synthetic repellent and insecticide. It is chemically similar to natural pyrethrins derived from chrysanthemum flowers. It is used to treat clothing, nets and gear. It provides long-lasting protection by repelling and killing insects on contact. You will find this in Lifesystems EX4 AntiMosquito and Craghoppers' Nosilife collection.

Image of Prallethrin

Prallethrin

Is another type of pyrethroid. It is an insecticide that is known for its rapid knockdown of mosquitoes, cockroaches, bed bugs and fleas. You’ll mainly find this used in mosquito coils.

Image of Saltidin (Also known as Picaridin/Icaridin)

Saltidin (Also known as Picaridin/Icaridin)

An effective DEET-free insect repellent. It works by throwing biting insects (like mosquitoes, ticks, and midges) off your scent and tastes unpleasant to them, protecting for up to 8 hours per application. It is also odourless and colourless, gentle on skin. It’s a good choice for children and sensitive skin. You will find this ingredient in Smidge.

Image of Citronellal

Citronellal

Citronellal is a naturally occurring monoterpinal aldehyde that provides a fresh, lemon-citrus aroma. It is the primary active component distilled from citronella grass varieties. Citronellal works by disrupting the sensory receptors of insects, confusing them and deterring them from landing on human skin or fabrics. It is commonly used against mosquitoes, gnats, stable flies, ticks, and ants. While it provides short-term deterrence (typically 1–2 hours) when applied directly to the skin, scientific consensus notes that it is significantly less effective and shorter-lasting than synthetic alternatives like DEET.

Image of PMD Citriodiol

PMD Citriodiol

A highly effective, plant-based insect repellent derived from the oil of the Eucalyptus citriodora tree. It is widely recognised as one of the best natural alternatives to DEET. It emits a cooling, menthol-like vapour that masks your natural carbon dioxide and body odours, disorienting mosquitoes, midges, ticks, and other biting insects. You'll find this in products like Lifesystems Natural Mosquito Repellent.

Repellents vs. Insecticides

Insect repellents discourage bugs from landing on you, while insecticides actively kill them. DEET, Citriodiol, Citronella & Saltidin are insect repellents. While Prallethrin and Permethrin are insecticides. Typically, repellents are applied directly to the skin, clothing or gear, while insecticides are present on treated fabrics or sprayed into the air.

Mosquito nets

Your guide to mosquito nets

Mosquito nets provide a physical barrier against insects, making them essential for sleeping in high-risk areas.

If you are travelling to a country where insect-borne diseases are present, a mosquito net is a must-have piece of kit.

A mosquito net provides a physical barrier between you and insects while you sleep. Some nets are also treated with insecticides or repellents. Lifesystems nets are treated with EX8 repellent, lasting up to 2 years and are re-treatable.
