DEET is the most common and effective active ingredient in insect repellents. It does not kill insects; instead, it creates an invisible barrier that makes it difficult for biting insects like mosquitoes, ticks, and flies to locate and land on you.

How Does It Work?

The exact mechanism is still debated, but the leading theory involves confusing the insect's senses:

Insect Attraction: Insects, particularly mosquitoes, are highly attracted to the carbon dioxide (CO2) and other chemicals (like lactic acid) that humans and animals exhale and emit from their skin.
DEET's Role: DEET is believed to either:

Block Odor Receptors: It binds to the insect's antennae, effectively blocking the receptors that detect human scents. The insect knows you are somewhere but can't pinpoint your location.
Create an Unpleasant Odor: It acts as an "olfactory camouflage" or emits a smell that the insect finds repulsive.

The result is the same: the insect is discouraged from landing on you and biting.

Key Uses and Effectiveness

DEET is used to protect against the bites of various insects, which is crucial for:

Preventing Discomfort: Avoiding itchy bites from mosquitoes, fleas, and gnats.
Preventing Disease: This is its most critical function. DEET helps prevent the transmission of insect-borne illnesses such as:

Mosquito-borne: West Nile Virus, Zika Virus, Dengue Fever, Malaria, Eastern Equine Encephalitis (EEE).
Tick-borne: Lyme disease, Rocky Mountain Spotted Fever.

Its effectiveness is directly related to its concentration:

Lower concentrations (10-30%): Provide protection for a few hours.
Higher concentrations (up to 100%): Provide longer-lasting protection, often for 10-12 hours. For most situations, a concentration of 20-30% is considered sufficient.

Safety and Precautions

DEET has been used by millions of people since its development by the U.S. Army in 1946 and registered for public use in 1957. It has a very strong safety profile when used according to directions.

Regulatory Approval: It is extensively regulated by agencies like the U.S. Environmental Protection Agency (EPA) and considered safe for adults, children, and pregnant women when used properly.
Proper Use is Key:

Apply to clothing and exposed skin only. Avoid applying under clothing.
Do not apply to cuts, wounds, or irritated skin.
Avoid contact with eyes and mouth.
Do not allow children to apply it themselves.
Wash hands after application and wash treated skin with soap and water after returning indoors.

Potential Issues: Improper overuse can sometimes cause skin irritation. In very rare cases of ingestion or extreme overapplication, more serious neurological effects can occur, which is why following label instructions is critical.

Summary

In short, N,N-Diethyl-m-toluamide (DEET) is a highly effective and widely tested insect repellent that works by interfering with an insect's ability to smell its human hosts. Its primary importance lies in its ability to prevent bites and reduce the risk of serious insect-borne diseases, making it a vital tool for public health.
