DEET is one of the most common repellents used by consumers. Although it is widely considered safe, there are a number of precautions you should follow before using it. In particular, you should be careful to avoid applying it to cut or inflamed skin. You should also wash your hands after applying it.
A study by the University of Florida determined that DEET is the most effective mosquito repellent. It interferes with the sense organs of mosquitoes. That means they will not recognize you. This means you can go outdoors with confidence.
The study did not address the ultimate measure of disease prevention, but it was found that the sprays provided maximal protection after 240 minutes. If you are at risk of malaria, it is recommended to reapply the repellent more frequently.
For most people, applying DEET directly to the skin is not a good idea. There are many potential side effects associated with it. One of these is the potential for chemicals to discolour cotton clothing.
Before purchasing a repellent, you should do a patch test. Apply the product to an exposed area of skin, such as a wrist, to see how it reacts. Be sure to read the label for instructions.
For best results, you should apply the product before dusk. Mosquitoes will bite at dawn and dusk. Using DEET before dusk will reduce your risk of getting bitten by mosquitoes during the day.
DEET-containing mosquito products are pleasant to smell. They confuse mosquitoes and leave behind a fresh scent.
