Use |
Mainly used as an insecticide, it is often used to prevent and control the larvae of various insects such as mosquitoes and flies. It can be used in indoor, outdoor, home and public places and other environments. |
DEET is widely used as an insect repellent for personal protection against biting insects. It is the most common ingredient in insect repellants and is believed to work as such in that mosquitos intensely dislike its smell. And it can be formulated with ethanol to make 15% or 30% diethyltoluamide formulation, or dissolve in suitable solvent with vaseline, olefin etc.
Application
The principle of DEET: First of all, we must understand the reason why humans attract mosquitoes: female mosquitoes need to suck blood to lay eggs and lay eggs, and the human respiratory system produces carbon dioxide and lactic acid and other volatiles on the human surface can help mosquitoes find us. Mosquitoes are so sensitive to volatiles on the human surface. So it can run straight at its target from 30 meters away. When a repellent containing Deet is applied to the skin, Deet evaporates to form a vapor barrier around the skin. This barrier interferes with the insect’s antennae chemical sensors to detect volatiles on the body surface. So that people avoid mosquito bites.
When applied to the skin, DEET quickly forms a transparent film that resists friction and sweat well compared to other repellents. The results show that DEET has stronger resistance to sweat, water and friction than other repellents. In the case of sweat and water, it can still be very effective at repelling mosquitoes. Water splashing includes swimming, fishing and other opportunities for substantial contact with water. After a lot of friction, DEET still has a repellent effect on mosquitoes. Other repellents lose their repellent effect after half of the friction.

Attentions
1. Do not allow products containing DEET to come into direct contact with damaged skin or be used in clothing; When not needed, its formulation can be washed off with water. As a stimulant, DEET is inevitable to cause skin irritation.
2. DEET is a non potent chemical insecticide that may not be suitable for use in water sources and surrounding areas. It has been found to have slight toxicity to cold water fish, such as rainbow trout and tilapia. In addition, experiments have shown that it is also toxic to some freshwater planktonic species.
3. DEET poses a potential risk to the human body, especially pregnant women: mosquito repellents containing DEET can penetrate into the bloodstream after coming into contact with the skin, potentially entering the placenta or even the umbilical cord through the bloodstream, leading to teratogenesis. Pregnant women should avoid using mosquito repellent products containing DEET.
