Mosquito Repellents for Summer 2024

Mosquito season is here, and with it comes the need to protect ourselves from these pesky insects. Mosquitoes are not just annoying; they can carry dangerous diseases such as malaria, dengue, West Nile, and Zika. Therefore, it’s essential to know what to look for in mosquito repellents to ensure effective protection.

What to Look for in Mosquito Repellents

The Centers for Disease Control and Prevention (CDC) recommends repellents with the following active ingredients for long-lasting protection:

  • DEET: One of the most effective and widely used ingredients.
  • IR3535: Another strong repellent that provides hours of protection.
  • Picaridin: Known for its long-lasting effectiveness.
  • Oil of Lemon Eucalyptus: A natural option, but be sure it’s the EPA-registered product, not the essential oil.

It’s crucial to note that lemon eucalyptus essential oil is not recommended by the Environmental Protection Agency (EPA) as it hasn’t been tested for safety. Similarly, the CDC does not endorse other “natural” products that haven’t undergone evaluation.

Additional Tips to Avoid Mosquito Bites

While repellents are a key defense, other strategies can help minimize the risk of mosquito bites:

  • Wear long sleeves and pants: This reduces the amount of exposed skin.
  • Avoid peak mosquito activity times: Dusk and dawn are when mosquitoes are most active.
  • Eliminate standing water: Mosquitoes breed in standing water. Empty buckets, kiddie pools, and other containers regularly.
  • Treat clothing and gear with permethrin: This pesticide helps ward off mosquitoes and other pests.

How Insecticides are Tested

The CDC operates a mosquito lab in Fort Collins, Colorado, where it tests insecticides. Researchers coat the inside of bottles with insecticide and then introduce mosquitoes to see what percentage die within two hours. This method is simple and cost-effective and is used both in the U.S. and globally.

Scientists repeat these tests each season to monitor changes in mosquito resistance. Accurate results can be challenging due to variables like the amount of insecticide used, but repeated testing helps identify resistance patterns.

Mosquito Resistance to Chemicals

Like bacteria with antibiotics, mosquitoes can develop resistance to insecticides. Pyrethroids, including permethrin, are common insecticides that have shown resistance. Despite this, they remain popular due to their effectiveness in controlling adult mosquitoes.

Community programs, farmers, and homeowners use pyrethroids, though resistance varies by product and dose. The CDC is working with state and local officials to conduct real-world field tests, such as checking mosquito mortality after fogging trucks pass by.

In conclusion, choosing the right mosquito repellent and following additional precautions can significantly reduce the risk of mosquito bites and the diseases they carry. Stay informed and protected this mosquito season.
