What You'll Learn
Electric fly swatters can cause burns
Electric fly swatters are considered safe devices for eliminating insects and are used widely in many countries, including Greece and Thailand. They are designed to kill mosquitoes and other insects by generating an electric flash of light when the screen touches the insects, incinerating them. However, they can also cause burns if not used properly.
There have been several reported cases of burns caused by electric fly swatters. In one case, a 31-year-old female presented to the Accident and Emergency Department with a 15% partial-thickness flame burn to both lower limbs. The patient had rubbed her lower limbs with an alcohol solution to relieve itching from mosquito bites. She then attempted to kill a mosquito with an electric fly swatter, holding the device approximately one meter away from her legs. The flame produced by the insect incineration ignited the alcohol, and her lower extremities were engulfed in flames.
In another case, a 2-year-old boy in Thailand sustained superficial partial-thickness burns to his face, neck, left upper extremity, posterior trunk, and bilateral lower extremities. The boy had been sitting near his father, who was painting the floor with flammable adhesive shoe glue. The boy used the electric fly swatter to kill a mosquito, and the hot device then ignited the glue and the boy's clothing.
To prevent burns, it is important to follow the specific instructions for use that come with electric fly swatters. These instructions include preventing the application of the metallic mesh to flammable surfaces and allowing the mesh to cool sufficiently after use. Adhesive shoe glue, in particular, is a known flammable substance that should be used with caution around electrical equipment. It should be stored in closed airtight safety containers after use. Additionally, electric fly swatters should be kept out of the reach of children to prevent accidents.
While electric fly swatters can be effective insect eliminators, it is important to be aware of the potential risks associated with their use. Proper handling and caution around flammable substances are necessary to prevent burns and other injuries.

They generate a high voltage
Electric fly swatters are battery-powered and generate a high voltage—between 500 and 3000 volts—when a button is held down. The voltage is applied between two grid or mesh electrodes. When an insect bridges the gap between the electrodes, a current passes through it, incinerating it. The capacitor attached to the electrodes discharges during the spark, usually stunning or killing the insect. If the button is kept depressed, the continuous current will rapidly kill and incinerate a small fly.
The capacitor is charged to a high voltage by a transformer, which boosts the voltage. The capacitor stores energy until an insect comes along to discharge it. A discharge resistor across the capacitor drains the capacitor when not in use, preventing accidental shocks.
Electric fly swatters are considered safe for humans, with a limit on the net charge stored in the capacitor. A discharge of less than 45 microcoulombs is considered safe, even if the current passes from one arm to the other, passing through the heart. The maximal continuous current of most fly swatters is less than 5 milliamperes, which is also safe.
However, there have been cases of people receiving burns from electric fly swatters. In one case, a woman received burns to her legs after using an electric fly swatter near her legs, which had been treated with an alcohol solution to relieve itching from mosquito bites. The flame produced by the insect incineration ignited the alcohol. In another case, a boy received burns after placing the electric fly swatter, which had recently been used and was still hot, onto a floor painted with adhesive shoe glue, igniting the glue and his clothes.

They are safe for humans
Electric fly swatters are considered safe devices for humans to use to eliminate insects, and they are used widely in many countries. They are designed to be safe for humans, with specific instructions for use, such as preventing the application of the metallic mesh to flammable surfaces and allowing the mesh to cool for a sufficient time after use.
The electric fly swatter consists of a racket-shaped electrical screen that is free of toxic and other chemicals. The device is activated by a push button, which charges the capacitor to a high voltage. The voltage is high enough to incinerate insects on contact, but the current is not strong enough to harm a human.
While the voltage of an electric fly swatter is high, the current is low, and the duration of a shock is very brief. For a shock to affect the human heart, there would need to be a path of electricity passing over it. In the case of an accidental shock from an electric fly swatter, the current is localized to the point of contact, such as a finger, and does not travel across the body. Therefore, while it may hurt and sting, it is not dangerous to the heart.
There have been rare reports of burns caused by electric fly swatters. In one case, a patient suffered a 15% partial-thickness flame burn to both lower limbs after using an electric fly swatter while having an alcohol solution on their skin. In another case, a 2-year-old boy suffered a 25% flame burn when he placed the electric fly swatter, which was still hot, onto a floor with adhesive shoe glue, which ignited. These incidents highlight the importance of following safety instructions when using electric fly swatters.

They are lightweight and easy to use
Electric fly swatters are an effective way to kill insects without the need for toxic bug sprays. They are lightweight and easy to use, making them a handy tool for camping trips or keeping your home insect-free.
The electric fly swatter is designed to be lightweight, with a handle made of lightweight materials such as wire, wood, plastic, or metal. This lightweight design allows for quick acceleration, helping you to overcome the fast reaction time of flies and other insects. The swatter typically has a small rectangular or round sheet of flexible, vented material attached to the handle, which is also made of lightweight, thin metallic, rubber, or plastic mesh. This mesh material is essential for minimizing air resistance, making it easier to target fast-moving insects.
The electric fly swatter is easy to use, requiring just the push of a button to activate. When the button is held down, the swatter generates a voltage of between 500 and 3,000 volts, creating a current that passes through any insect that comes into contact with the mesh. This initial discharge is designed to stun or kill the insect, and if the button is held continuously, it will rapidly incinerate smaller insects.
The lightweight and easy-to-use design of electric fly swatters makes them a convenient and effective alternative to traditional fly swatters or bug sprays. They are simple to operate and can be used both indoors and outdoors to keep your environment insect-free. However, it is important to follow the safety instructions provided with the device, such as keeping it away from flammable substances and allowing it to cool down sufficiently after use.

They are more effective than traditional fly swatters
Electric fly swatters are more effective than traditional fly swatters for several reasons. Firstly, they do not require the user to mechanically crush the fly against a surface, which can be a messy and unhygienic process. Electric fly swatters kill insects when they are airborne, rather than waiting for them to land on a surface. Insects on a surface will often take flight as the swatter approaches, making them easier to target.
Secondly, electric fly swatters are more effective at killing small insects. The voltage generated by the battery-powered high-voltage generator in the handle of the swatter, typically between 500 and 3000 volts, is enough to stun or kill small insects like mosquitoes, flies, and gnats. The capacitor attached to the electrodes discharges during the spark, stunning or killing the insect.
Thirdly, electric fly swatters are more effective at preventing insects from escaping. The speed and agility of flies make them difficult targets, but electric fly swatters only require contact with the insect to be effective, whereas traditional fly swatters require more accuracy to generate enough force to crush the insect.
Additionally, electric fly swatters are more effective at avoiding damage to other objects. Traditional fly swatters rely on force to crush the insect, which can result in accidental damage to surrounding objects. Electric fly swatters, on the other hand, only require contact with the insect, reducing the force needed and minimizing the risk of damaging other items.
Lastly, electric fly swatters are more effective at maintaining hygiene and avoiding the use of toxic chemicals. They eliminate the need for toxic bug sprays, making them safer for both the user and the environment. This eco-friendly aspect of electric fly swatters is a significant advantage over traditional fly swatters, which do not offer a chemical-free method of insect control.
