    A mosquito coil is a special type of mosquito repelling solution made from dried pyrethrum powder. As its name implies, a mosquito coil is a spiral that burns slowly when lit. The smoke produced by the slowly burning coil is an effective mosquito repellent. The coil is suspended in the air by a mosquito coil holder to keep it burning all throughout.

    Mosquito coils are usually 4 to 6 inches in diameter and can last within 4 to 7 hours. This special type of repellent in is common in countries in the tropical and sub-tropical countries where there is a warm and humid environment.

    How Does A Mosquito Coil Work?

    Basically, there are two types of mosquito coils with regards to their main function. Mosquito coils formulated with an insecticide produce an incense smoke that can knock mosquitoes down effectively. On the other hand, coils formulated with an essential oil extract such as citronella deliver a repelling effect against mosquitoes.

    The following video will take you deep into the manufacturing process of mosquito coils.

    Mosquito coils are often used with holder to suspend it horizontally in the air. The outer end is then lit, burning the incense slowly from the outside of the spiral towards its core.

    The smoke produced by the burning coil either knocks the mosquitoes down or repels them. Depending on the wind condition of the environment, mosquito coils can cover an area of up to 100 square feet.


    Are Mosquito Coils Effective?

    Yes! As mentioned earlier, there are two types of coils based on its content. A coil formulated with insecticides has the capability of killing or knocking mosquitoes down.

    However, the downside of such coil is that it gives off a rather strong and irritating scent that can be very unpleasant.

    The second type of mosquito coil is made of a plant-derived ingredient such as citronella extract. But unlike the former, this new type of coil is more a repellent than a mosquito-killing incense.

    Did You Know

    A female mosquito will stop biting only if her abdomen is already full. After that, the mosquito rests for two to three days until she is ready to lay her eggs.


    Are Mosquito Coils Safe?

    Smoke produced from burning mosquito coil is indeed in killing and repelling mosquitoes. But does it pose a risk on human health?

    Recent studies have shown that being smoke coming from a single mosquito coil is equivalent to that produced by 75-137 cigarettes. And such risk is increased if mosquito coils are used indoors to eliminate blood sucking insects that have penetrated into the house.

    This is definitely the main reason why mosquito coils are recommended for outdoor use. In some cases, mosquito coils are used inside the house but it is best to first make sure that the area is well ventilated.


    How To Use Mosquito Coils?

    In most cases, mosquito coils are paired together in packaging. You should be very careful in separating the two since mosquito coils are fragile and may easily break. The technique is to loosen the two coils from the center and slowly working your way outwards.

    Most mosquito coil packages come with a coil holder or stand to suspend the coil in the air. Raise the center part of the holder and insert it into the preshaped slot of the coil.

    Light the tip of the coil and secure it on a metallic plate to collect the ash. Place the burning coil on your patio, yard, or garden to kill or eliminate mosquitoes.

    Murphy’s Naturals incense sticks not only smell great; they also make mosquitoes beat a hasty retreat! I know most of the list is based around coils, but this is just a coil that got straightened out, and with it using all natural-oils to do its work, I thought it deserved a place here.
