Midges are a flying plague that any walker in Scotland will no doubt dread meeting while exploring the countryside.

These tiny flying insects can make a summer stroll the most miserable and irritating experience in the space of just a few minutes.

Last year we tested a number of different repellents from various suppliers to help you pick one that may do the job for you. In this second of our series of reviews we are looking at a product that I personally have used for a number of years and one that is always found in my day pack.

Life Systems Midge and Mosquito Repellent Spray

Life Systems is a well respected manufacturer of numerous products that aid in making your outdoors adventures more bearable. Their Midge and Mosquito Repellent Spray combines myrtle extract (a small plant known for it’s essential oils)  with DEET to provide protection from small biting insects which Life Systems claim can last for up to 8 hours.

So what is DEET?

DEET (or diethyltoluamide) is the most common active ingredient in insect repellents and was originally developed for use as a pesticide for agricultural use. It provides protection against mosquitoes, ticks, fleas, chiggers, leeches, and many more biting insects.

There are a few things you should consider before using a DEET based substance…

  • DEET is effective but it does not agree with everyone especially those suffering with respiratory problems such as asthma.
  • It can also irritate people with sensitive skin and this the reason that it is normally diluted down to 50% in most repellents.
  • Repellents containing DEET are not suitable for children under 16 years old.
  • DEET is also known to have a corrosive effect on some modern fabrics (e.g. light shell jackets) and plastics so care has to be taken when applying it.

Tough design

The repellent is supplied in a 50ml pump spray bottle. The bottle is made from a metal alloy and is tough enough to survive the toughest of trips with a  few knocks along the way. Having tough packaging is must in my eyes as opening your pack to discover that your spare kit and snacks have been covered with insect repellent is guaranteed to spoil a day’s walking.


Apply carefully to all exposed clean and dry skin except for eyes and lips. For use on face, spray into palm of hand before applying. Re-apply as necessary depending on conditions such as temperature, humidity and other environmental factors can reduce the duration of protection of all insect repellents.

Is the repellent any good?

Yes. The repellent does a good job of driving away midges and flies and is effective for quite a while. The repellent’s smell is fairly innocuous which is good as some formulas have a distinct chemical tinge to the smell which can be just as annoying as midges (not quite though!). When used in conjunction with a midge net, the repellent works very well in even the most dense of midge swarms just remember to make sure you don’t spray it on to your favourite trekking jacket!
