How to Choose and Use Mosquito Control Repellents Wisely
Mosquitoes know when humans are nearby. Even from a distance they can sense the heat and carbon dioxide that we give off. The way mosquito repellents typically work is by masking those cues that attract mosquitoes. Because several important diseases are transmitted by mosquitoes, it’s important to use a good mosquito repellent.
Mosquito repellents work better for some people than others. The level of protection is not equal. The age and level of activity of the person involved vary as do the gender and type of mosquito. Another important point is that these repellents only work on the surface they’re applied to. Good coverage is a must.
One of the most effective repellents is DEET. Another good one is picaridin. The Center for Disease Control (CDC) recommends these products because they work well and offer long lasting protection. DEET was first offered for sale in 1957 and has an excellent safety record.
The length of time you’re outside can help you determine what concentration your mosquito repellent needs to be. If you’re often outside 3-4 hours, you’ll need a product with 20% or more of DEET for good protection. If you’re typically outside for less than 3 hours, consider a product with less than 20% DEET or 7% picaridin. Products with more than 50% DEET do not offer any extra protection.
According to various agencies and organizations, these mosquito repellents products are safe. Environmental Protection Agency (EPA) says DEET does not pose any health threat and is not a human carcinogen. The CDC recommends not combining sunscreen products with other products containing DEET. According to the American Academy of Pediatrics products that contain DEET are safe to use on children over two months old.
There are two other active ingredients recommended by the CDC. These ingredients provide good protection but not for the length of time as higher concentrations as DEET. The two products are oil of lemon eucalyptus and IR3535. Testing by EPA says that oil of lemon eucalyptus provides protection that lasts as long as lower concentrations of DEET. Children under the age of 3 should not be exposed to this ingredient, so be sure to read the label of the specific product you choose.
In spite of widespread advertising, there is no scientific evidence that the ultrasonic mosquito repellent devices work. Current beliefs that eating garlic, vitamins, onions, or any other food can repel mosquitoes are not true. The portable mosquito traps that emit carbon dioxide are too new to have been thoroughly tested yet.
Here are the ground rules for using mosquito repellents safely: Read and follow the instructions on the label. Only apply these products to exposed skin. Don’t use these products under clothing. Don’t apply to cuts, wounds or rashes. Don’t apply near eyes or mouth, and apply lightly around the ears. Don’t allow children to apply these products. When you return indoors, wash with soap and water or bathe.
