DEET is best

 

The DEET repellent was the most effective in our test. It was seven hours before any of the volunteers received a bite.

 

Picaridin products

 

The two products containing picaridin (Apex Repel New Era and Skin Technology New Generation) were the best of the non-DEET products. It was two hours before a mosquito attempted a bite on two of the volunteers and three hours before all four received a bite. These two products clearly outperformed the natural repellents.

 

Natural products

 

The natural products offered limited protection. The Kiwicare Safari wipes repelled the mozzies well for a short time after application but a bite was recorded within an hour. The MozzyOff and Tui Bug Balme products offered the least protection.

 

There was some protection, with fewer landings once the products were applied. While you could use them at a backyard barbecue, we wouldn’t advise taking them on the Milford Track – or on a South Pacific holiday during the rainy season.

This was a very demanding test – you’re unlikely to find so many mosquitoes in such close proximity in the wild. So our results should be treated as guidelines. How long a repellent’s effect lasts will depend on the conditions and on your activities – sweating will shorten your protection time.
