When it comes to mosquitoes, the biggest question most people have is how to keep them away. It can be challenging to know where to begin, with the number of products claiming to do this and repel that, and all the DIY methods that promise just as effective results

Repellent products can be hit and miss, and many popular DIY methods that work for some might not work for others. One way to repel mosquitoes that is supposedly effective is by using mosquito repellent coils—but do these actually work?

What are mosquito repellent coils?

Repellent coils are a popular DIY method for helping keep mosquitoes and other flying insects away. It’s an incense-like product that is spiral-shaped and made of dried paste that burns slowly to release smoke that repels flying insects from the area. The mosquito coil is typically suspended in the air, either hung or in a holder, to promote continuous burning.

How do mosquito repellent coils work?

Mosquito repellent coils produce smoke when burned, which contains chemicals that repel mosquitoes and other insects. Modern mosquito coils use pyrethrins, which are derived from chrysanthemums. Pyrethrins are insecticidal, meaning that they kill or repel insects, including mosquitoes. There are also other mosquito coils that use natural insecticidal oils such as citronella, rosemary, lemongrass, and eucalyptus. The burning usually begins at the end of the spiral, working its way to the middle of the coil and releasing smoke meant to help keep mosquitoes away.  

Are mosquito repellent coils effective? 

Though repellent coils are a popular DIY solution for mosquito prevention, there is still the outstanding question of whether or not they are effective. Even though these coils are easily available and inexpensive, they are not as effective as they seem. While they may provide some temporary relief from mosquitoes in a small area, mosquito coils are not effective in larger spaces and are not a long-term solution. Hiring a professional is always the most effective and safest option for mosquito control.

Risks with mosquito repellent coils

It's important to be cautious while using mosquito coils as there are many risks associated with them. Here are some of the most common risks to consider when using this product:

  • Respiratory issues: The smoke released from mosquito repellent coils can cause respiratory issues, especially for people with asthma or other pre-existing respiratory conditions.

  • Fire hazard: Repellent coils are a fire hazard, and they should never be left unattended. Make sure to keep them away from flammable materials and out of reach of children.

  • Toxicity: mosquito repellent coils contain chemicals that, when inhaled, may cause some health concerns, such as nausea, headache, dizziness, and skin irritation.

  • Environmental concerns: When burned, mosquito repellent coils can release pollutants into the air and may have harmful effects on the environment, including water sources, wildlife, and plants.

To minimize the risks, it's essential to use mosquito coils safely and follow the instructions on the package. Make sure to use them in well-ventilated areas, and do not use them indoors. If you experience any harmful reactions, seek medical attention immediately.
