Insect repellent DEET explained

What DEET is?

DEET or diethyltoluamide (N,N-Diethyl-meta-toluamide) in its official chemical name is the most popular active ingredient used in many insect repellent products, and for now also the most effective one. DEET is used for repelling not only mosquitoes, but also other pests that carry diseases such as ticks. DEET has got an oil consistency with a yellowish color. The history of DEET actually goes more than 50 years back and it was developed by the U.S. Army in 1946 and was used during the World War II by U.S. Army in areas with high mosquito activity such as jungles, where was a higher chance to get infected with mosquito-borne diseases. Today DEET is used in many commercial insect repellent products as an active ingredient in combination with other substances and are available to purchase for all people. Some research says that DEET is used by over 30 percent of Americans each year to protect themselves from insect and pest problems, which is a significant number and shows how large actually the mosquito problem is in the USA.

How it works

DEET should be applied directly on skin or clothing. How DEET works is that is doesn’t kill mosquitoes, but just repels them for certain amount of time. For insect killing you must use a mosquito fogger with a special insecticide formula. DEET makes us invisible to mosquitoes, by blocking signals mosquitoes can detect from our body such as heat, moisture and carbon dioxide. The interesting part about DEET is that there are no certain evidence of how DEET works and why mosquitoes aren’t able to detect humans when DEET is applied to the skin, but the most believable explanation is that DEET simply blocks our body scent to mosquitoes. For now, DEET is the most effective active ingredient for insect repellents and there are no other substances that can hide us so well from mosquitoes.

Concentrations

DEET in mosquito repellent products can be found in concentrations up to 100%. The higher concentration of DEET a mosquito repellent contains, the longer time it is going to provide protection. For example, 100% DEET is going to provide protection up to 12 hours, while DEET with 20% concentration will provide protection for couple of hours. In comparison, more natural insect repellents that contain citronella oil, which is a natural mosquito repellent will provide just half an hour to hour long protection. Most insect repellents contain DEET in concentration between 20 and 50 percent. The best way to find a suitable insect repellent for different outdoor activities is to know for how long time you are going to be outdoors, the longer you’ll need a protection against mosquitoes, the higher DEET concentration repellent you need to buy. After protection of repellent has been vanished you can reapply repellent again to the skin to renew the protection. lotion containing DEET
