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 don't work exactly the same for everyone. They work better for some and not as well on others. The factors involved include the age, gender and activity level of the person involved. The type of mosquito is a factor as well. Another important fact is that mosquito repellents only work on the surface they're applied to.
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 amount of active ingredient in a mosquito repellent is very important. The higher the concentration of active ingredient, the longer the protection lasts. If you're normally outside for 3-4 hours, a product with 20% or more of DEET offers good protection. If you're typically outside for less than 3 hours, products with less than 20% DEET or 7% picaridin offer 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.
The CDC recommends two other active ingredients that typically provide reasonably long protection, although not as long as the higher concentrations of DEET. They are oil of lemon eucalyptus and IR3535. Oil of lemon eucalyptus is a synthetic version of the real product. EPA's testing indicates that oil of lemon eucalyptus provides protection similar to low concentrations of DEET. Read the label however, as that product should not be used on children under 3 years of age.
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.
