If you’ve ever used insect repellent, you’ve probably wondered how bad it is for humans. While no chemical is completely safe, it’s important to avoid inhaling it. Using repellent can cause allergic reactions, rashes, and even seizures in some people. To minimize these effects, it’s important to wash off the repellent before going indoors or sleeping.
To protect yourself and your family from insect bites, you should use insect repellent with DEET. DEET contains the active ingredient DEET, which has been proven to repel mosquitoes and ticks. It is best to use insect repellent with a concentration of no more than 50%.
Another common ingredient in fly repellents is permethrin, a synthetic derivative of chrysanthemum flowers that has been used for decades to keep off insects. Permethrin has also been proven to be effective in killing insects and mites. In fact, the US Army has been using permethrin on combat uniforms for over two decades.
Insect repellents with deet are safe for most people when used properly. It should be applied according to manufacturer instructions and follow basic precautions. While some products have 100 percent deet, it is not necessary to use them. The concentration of deet affects the effectiveness and duration of the repellent. Some products with a concentration of 25-30% DEET are effective for several hours. Higher concentrations increase the risk of exposure without improving repellency.
