Mosquitoes live all over the world, though their concentration is higher in some places than others. Tropical areas, swamps, and warm places with high humidity are more likely to experience heavy infestations. In the United States, the three states that experience the worst mosquito infestations are Florida, Georgia, and Alaska.

In addition to being a nuisance, mosquitoes can be dangerous. They carry potentially deadly viruses, which tend to be more dangerous for people with frail immune systems like the elderly, young children, and immunocompromised individuals.

You should be able to enjoy the summer without worrying about itchy bites and potential illness. In addition to wearing mosquito repellent and protective clothing, there are many objects you can use to keep your home free of mosquitoes. Certain fragrances and chemicals are known for disrupting the ability of mosquitoes to sense humans.

One of the most common solutions to keeping mosquitoes away is to burn citronella candles. It’s true that the smell of citronella has a repelling effect on mosquitoes. But there are other substances that may have a more pronounced effect. One question is whether burning substances and inhaling the smoke is worse for your health than a mosquito bite.

Strongly smelling plant material has been used to keep mosquitoes away in many countries for centuries. The burning of different plants has a well-documented cultural history throughout countries all over the world. In the early 1900s, a pair of Japanese entrepreneurs created the world’s first traditionally-shaped mosquito coil in the distinctive spiral that these coils take today.

The first mosquito coils used incense created from pyrethrum paste. Today, though, the majority of models have evolved to incorporate plant-derived substances or pyrethroid insecticides. These materials are cheaper to produce and incorporate. The coils are highly portable and do show effectiveness in reducing mosquito bites.

How Mosquito Coils Work

There are a number of different mosquito coils on the market. They all incorporate the same basic principle of burning substances to create smoke that deters mosquitoes. The mix of substances can vary from design to design. The active ingredients are substances that deter mosquitoes from biting, while the coil also has materials to hold the shape together and slow down the smoldering process.

The coils can work in two different ways. If the coil contains insecticides, then the smoke it emits will kill or stun the mosquitoes. Meanwhile, coils that have aromatic plants help to repel mosquitoes by confusing their sense of smell. They make it more difficult for mosquitoes to sense you and bite.

There have been multiple studies regarding the role mosquito coils play in killing mosquitoes and preventing the spread of disease. Regardless of the exact chemical formula used, the majority of coils on the market will reduce a mosquito’s ability to bite a person. The question is whether mosquito coils are effective enough to prevent bites entirely, which is what helps prevent the spread of disease.

Health Concerns Regarding Mosquito Coils

Some health concerns have been raised regarding the burning of mosquito coils. As with any type of smoke, people are worried about the effects that the chemicals inside can have on their lungs when they inhale. In addition, experts are concerned enough about indoor mosquito coil burning that you should only burn these outdoors.

For the most part, the insecticides within the product are considered to be safe. However, there are other particles that make up the coil itself. When the coil smolders, it creates particulate matter. If the coil is burned indoors, and the air is given no way to vent, then the smoke can have the same ill effects on your lungs as smoking dozens of cigarettes.

According to the results of one study, a single mosquito coil gave off enough smoke matter that the particles reached the equivalent of between 75 and 137 cigarettes. Exposure to this much smoke immediately increases your health risks. However, there hasn’t been a great deal of research regarding long-term mosquito coil exposure while outdoors. It’s not clear whether mosquito coils might increase the risk of lung cancer or not if used frequently.

Choosing the Right Mosquito Coil

When you’re picking a bug spray, you’ll often see concentrations of active ingredients that make up at least ten percent of the bottle. But with mosquito coils, the coil is so densely constructed with slow-burning matter that it’s common to see active ingredient concentrations of less than one percent.

Coils all tend to follow the same basic principle. When you’re picking the right ones for you, keep in mind the amount of time you want them to burn. Slow burns of four hours are good for afternoons spent outdoors, while longer burns are good for camping trips.

Check Price

With these mosquito coils, each package includes eight full coils. They’re longer burning timewise than many of the other options on the market, and the eight coils per pack can last for a long time. Every coil provides between five and seven hours of bug repellent.

The packages are available as a single box that contains eight coils, two boxes containing 16, or three boxes containing 24. If you’re planning to spend standard periods of time outside, a box of 16 can last for more than two weeks. If you’re working in an area of greater than 100 square feet, you should place a coil at the center of every 100 square foot radius to maximize protection across the grounds.

The coils are designed for use on cabanas, campsites, and patios. They create smoke barriers that drive away mosquitoes and other flying insects.

#2. SC Johnson Country Fresh Scent Mosquito Coil

These mosquito coils are available in refill packages so you can replace your original coils when they burn down. SC Johnson is well-known for creating multiple products for use around the household and family. These coils come with six refills per package, and they have the freshest scent of any of the formulas on the list.

Each coil can burn for up to four hours and offers one hundred square feet of protection. As such, you’ll need to replace them more often than the previous item on the list. However, the scent is pleasant enough that you may consider the cost of replacements worth it. Many other mosquito coils can be scented too strongly.

#3. Coghlan’s Mosquito Coil 8686

Coghlan’s is a brand that creates insect repelling and camping equipment that can protect you during your outdoor adventures. They create mosquito netting and tenting in a variety of different packages. These mosquito coils are some of the best on the market. They do have a rather strong scent, and you should keep the product out of reach of children. In addition, there are warnings that some of the chemicals and substances used can increase the risk of disease if you inhale them for too long.

Every box comes with ten coils, and every coil can last for eight hours. If you burn just one at a time, a single box will give you eighty hours of outdoor protection. In addition to having the coils themselves, the original box includes two metal stands to mount them on as they burn. If you already have the metal stands, you can get a simple refill for the package.

Final Thoughts

If you want a package of coils that burn for long periods of time, the Pic burners are a great option. Each coil can smolder for between five and seven hours, which is significantly longer than the four hours of the toughest competition. You’ll just need to place one coil within the center of every 100 foot radius, which is true of the other two options as well.

The Country Fresh coils from SC Johnson are a great option from a family-friendly manufacturer. Though they don’t burn as long, and you’ll need to buy replacements more often, they have a much more pleasant overall scent than the Pic burners.

Each of the coils in the Coghlan’s package can last for up to eight hours, outstripping even the Pic coils. They also come with two metal stands that allow you to mount and burn the coils with ease. With that said, they also tend to be one of the most expensive. Because of the unusually long burn time, the Coghlan’s coils are best suited for people who will be outside for most of the day. Campers in particular might benefit.
