DEET (diethyl-meta-toluamide) has been used for many years now as an effective insect repellent. However, some people experience irritation or an allergic reaction to repellents containing the chemical. If swallowed DEET is toxic and potentially fatal. This means that great care should be taken when applying to the hands or face or anything a child may put in the mouth. DEET should not be applied to areas of broken skin or around the eyes. It can also damage some plastics and synthetic fabrics, such as nylon and acetate.

DEET enters the bloodstream through the skin. Many people can use a repellent containing the chemical without incident. However, some people will suffer side effects ranging from rashes to severe muscle twitching.

Campers using DEET should be aware that using for a few days and not washing could lead to serious reactions.

What is Neem?
The Neem tree or Indian Lilac tree has been used for centuries for the protection of people and animals against insect pests. Extracts from the Neem tree have distinct therapeutic properties. Neem oil is cold pressed from the seed of the Neem tree and is a powerful natural insect repellent. The oil has been tested extensively on the Highland midge by a team of leading experts in Edinburgh. They found that midges have highly sensitive antennae and could detect Neem oil from the air. The scent of Neem oil prevents the midges from biting. Neem leaf extract is a tincture of shade dried Neem leaves and has soothing properties to help heal damaged skin.
