Safer Bug Spray: Natural Bug Repellents

Natural Insect Control: Other Ways to Beat the Bugs

Natural bug sprays aren’t the only nontoxic ways that you can fight back against mosquito bites and other bugs. Here are some other approaches to natural insect control – see which ones work and which don’t.

  • Long sleeves and pants. Yes, it’s probably obvious. But one good form of natural insect control is to cover your arms and legs. While a mosquito might be able to get through very thin clothing, moderately thick fabric will stop them. “No mosquito is going to bite you through a canvass shirt,” says Lunder.
  • Fans. Here’s a natural insect control tip. Mosquitoes have trouble maneuvering in wind. So when you’re sitting out on our porch, think about using a window fan or overhead fan. The mosquitoes will have trouble getting near you.
  • Environmental control. Eliminate standing water in your yard, which will prevent mosquitoes from breeding. Empty bird baths weekly and fill puddles with dirt.
  • Citronella candles. Despite the lore, citronella candles – or other natural bug repellent candles – don’t seem to work very well. They could even have risks. “I’d caution people about burning bug-repellent products, like citronella candles,” says Lunder. “Inhalation is a very direct form of exposure, so you’re breathing in whatever chemicals are in the product.”
  • Bug zappers. Don’t bother. Sure, they may electrocute loads of bugs, but they usually kill beneficial insects that eat pests or serve as food for birds. One study showed that of all the insects slaughtered by bug zappers, a mere 0.13% were biting mosquitoes.
  • Ultrasonic devices. Again, don’t bother. They don’t work.
  • Traps. Relatively new on the scene, these devices use various methods to attract and then trap mosquitoes. Many give off carbon dioxide, mimicking a breathing animal or person. While they certainly do trap mosquitoes, experts aren’t sure how well they control mosquito populations in a given area. You’ll also have to decide whether the device itself – which might run on a gas-powered engine – is preferable to the bugs.
  • Permethrin-treated products. Permethrin is a kind of chemical repellent that’s added to some clothing, shoes, and camping gear. While the idea of wearing a shirt treated with an insecticide might make you uneasy, Lunder points out that it has an advantage.

    “It’s not being applied directly on your skin, so it could be a really good option,” she tells WebMD. However, Lunder cautions that you should probably wash permethrin-treated clothing separately from other laundry. Like DEET, permethrin is a neurotoxin that can affect the nervous system.  You may want to weigh using either chemical against the risk of disease-carrying insects.
