Warm weather brings more than ice cream and beaches. It also brings swarms of biting bugs. Families will do just about anything to stop bugs from ruining their summer or vacation fun. The trick is to use repellents that donít bite back.
At any moment, there are about 10 quintillion bugs on Earth. (Thatís a 10 followed by 18 zeros!) And the two insect repellents most commonly used to shoo them away are DEET, a chemical developed by the military, and permethrin, a synthetic version of substances found in chrysanthemums, which is used to treat clothing and other items.
Is DEET safe? Both DEET and permethrin strongly discourage mosquitoes, flies, ticks, and other pests, but they donít necessarily do it safely. Recent studies, for example, find that DEET is a neurotoxin that may cause long-term health effects on adults and children. Reports have linked DEET to rashes, headaches, seizures, and other conditions. For its part, permethrin is listed as a likely human carcinogen. Permethrin is suspected of disrupting the endocrine and nervous systems. Thereís also evidence that DEET and permethrin enhance each otherís effects when used together.
Another option is picaridin, a chemical based on pepper. Itís said to be slightly less effective than DEET but believed to have low toxicity. Additional, more complete information on it would be welcome.
For a healthier approach to repelling bugs, skip these chemicals and practice prevention instead. Cover up your children with long sleeves and pants tucked into socks, and wear colors that blend in with your background. Avoid wearing scented products, which can attract insects. When you or your children need a bug spray, try natural solutions like these:
- Repellents using soybean oil can protect against mosquitoes for up to eight hours.
- Oil of lemon eucalyptus-based repellents have been proven as effective as DEET (according to the CDC). One important note: do not use them on children under age three.
Remember that natural repellents may need to be applied more frequently. They also donít contain many of the other ingredients conventional sprays do, like petroleum byproducts and synthetic fragrance, which can also be harmful to human health. After all, the point is to harm the bugs, not the humans or other animals theyíre nibbling on.
If you do choose to use DEET to repel insects despite the body of evidence against it, never use it on newborns under two months of age. Everyone else should apply a solution containing 30 percent DEET or lessóstudies show that higher concentrations offer no additional protection. When applying DEET, use sparingly, donít let children apply it themselves, and always keep it away from their eyes, mouths, hands, and wounds. And don’t let kids hug or snooze with a freshly-sprayed family pet.
