DEET is a synthetic chemical that has been used for many years as an effective mosquito repellent. It is used in products such as insect sprays, lotions, and creams to keep mosquitoes away from the skin. DEET works by blocking the signals that female mosquitoes use to find and detect humans as their blood source.

The benefits of using DEET as a mosquito repellant are clear: it is highly effective at keeping mosquitos from biting and potentially transmitting disease-causing viruses or parasites. However, although DEET is considered safe when used appropriately, there are still some risks associated with its use. Prolonged exposure may cause irritation or burning sensations on the skin and eyes, and there have been rare reports of neurological symptoms associated with frequent or excessive use.

In order to make sure you reap the benefits of DEET without running any unnecessary risks, it’s important to follow the label instructions when using products that contain this chemical: apply sparingly and in a well-ventilated area, don’t use under clothing, and wash off after returning indoors. Additionally, be aware that DEET is most effective at repelling mosquitoes when used in concentrations of 20-30%. Anything above 50% will not increase its effectiveness against mosquitos but may increase your risk for irritation or other side effects.
