Bear Grylls Mosquito Repellent is a DEET-free, eco-friendly repellent designed to keep mosquitoes away. It’s perfect for outdoor enthusiasts and anyone seeking a safe, non-toxic alternative to traditional repellents. We use Citriodiol® as the active ingredient in our sprays.

Citriodiol® is a registered brand name for a highly effective, plant-based insect repellent ingredient derived from the oil of the Lemon Eucalyptus tree. Its active repellent component is PMD (p-menthane-3,8-diol), which is the substance independently studied, tested and approved by regulators worldwide.

Bear Grylls Mosquito Repellent uses Citriodiol® at the highest concentration permitted for use on human skin, delivering strong, long-lasting protection without relying on harsh synthetic chemistry. This balance of performance, safety and reliability makes it well suited to real outdoor adventures.

Bear Grylls Mosquito Repellent provides broad-spectrum protection against many of the most common and troublesome biting insects, including:

• Mosquitoes (including species known to transmit disease)
  
• Ticks
  
• Midges and gnats
  
• Sand flies
  
• Horse flies and black flies
  
• Other nuisance biting insects
  

Scientific studies on PMD, the active component of Citriodiol®, consistently show effective repellency across multiple insect species, making it a dependable choice for varied outdoor conditions.

When applied correctly, Bear Grylls Mosquito Repellent can provide up to 6–10 hours of protection against mosquitoes and other biting insects. Actual duration depends on factors such as temperature, humidity, sweating and (of course) physical activity.

This level of performance places Citriodiol®-based sprays among the most effective non-synthetic repellents available and supports confident use during extended time outdoors.

Yes. While Citriodiol® is the commercial ingredient name, its active repellent component (PMD) has been extensively reviewed and approved by regulatory authorities around the world.

PMD-based repellents are recognised by organisations such as:

• UK and EU biocidal product regulators
  
• The US Environmental Protection Agency (EPA)
  
• Health and environmental authorities in Australia and Canada
  

These approvals are based on assessments of both effectiveness and safety, so you can be sure that our spray meets the highest of international standards.

Yes. When used as directed, Citriodiol®-based repellents are considered suitable for family use. Many health authorities permit PMD-based repellents for children from around 6 months of age.

Bear Grylls Mosquito Repellent is also strong enough to be used by adults, including pregnant or breastfeeding individuals, when applied according to instructions. As with all repellents, it should be applied by an adult when used on children and kept away from eyes and mouth.

For best results:

• Apply evenly to all exposed skin before going outdoors
  
• Spread gently and allow to dry before heavy activity
  
• Reapply if you’ve been sweating heavily, swimming, or after several hours of continuous exposure
  
• Avoid applying to broken or irritated skin
  

Using the product correctly ensures consistent protection throughout your adventure.

Yes. If you’re using both, apply sunscreen first and allow it to absorb fully. Then apply Bear Grylls Mosquito Repellent.

If you later reapply sunscreen, be aware this can reduce the effectiveness of the repellent and may require you to reapply it sooner.

Bracelets and clothing patches can offer additional or localised protection, particularly around gear or specific areas. However, scientific evidence shows that sprays applied directly to exposed skin remain the most reliable and effective form of insect repellent.

For environments with high insect pressure or for extended outdoor use, Bear Grylls Mosquito Repellent spray provides the most consistent, research-backed protection.

Consider purchasing a bundle including both bracelets and spray for the maximum adventure protection.

Scientific studies show that PMD-based repellents (the active component of Citriodiol®) can offer protection comparable to DEET products in most real-world situations.

Bear Grylls Mosquito Repellent also offers advantages valued by many users:

• Plant-based active ingredient
  
• Does not damage plastics or synthetic fabrics
  
• Biodegradable profile

• Suitable for use by families and children
  

This makes it a strong alternative for those who want proven performance with a more nature-derived formulation.

We’ve created a dedicated Active Ingredient page explaining how Citriodiol® works, the role of PMD in insect repellency and how global regulatory approvals support its use.

Summary:

Citriodiol® is the branded formulation, while PMD is the scientifically studied active repellent. Together, they deliver a trusted, globally approved solution for effective insect protection; this is aligned with Bear Grylls’ ethos of dependable performance in the outdoors.
