There is a variety of options on the market, some of which are meant for outdoor use while others are safe for applying in the house.
Outdoor mosquito killers are the most common type and that makes sense because to rid your house of mosquitoes, you should start with their breeding sites outside it. With this in mind, the first thing you should do is to put larvicides in standing water in your yard. These are granules containing bacteria that prevent the larvae from developing.
Outdoor traps attracting bloodsuckers using carbon dioxide, heat, water, and the UV light will help you cut mosquito populations without the use of chemicals. If you are going hiking, camping or hunting, you will need an electric trap providing a smaller coverage. Fogging is a good way to create a mosquito-free space but it works only for a short time. This approach is particularly helpful for those who are going to host a party in the yard.
The most recommended option for indoor use is bug zappers . These are electric devices that lure insects with the help of ultraviolet light and instantly kill them by electric shock. Some products allow for adding chemical attractants, but such options are not recommended for installing indoors. An electric swatter equipped with an electric grid is a great choice for killing flying insects in the house.
Below, you will find a review of the 16 best mosquito killers. These are larvicides killing mosquitoes before they mature, liquid insecticides – both chemical and natural ones – and mosquito traps. The latter ones draw insects using ultraviolet light, CO2 or water and then kill them by electricity or through dehydration.
This 30-ounce bottle contains granules coated in Bacillus thuringiensis serotype israelensis (Bti) , which is bacteria used to control insects at the larval stage. These bacteria produce toxins, which, once ingested, destroy the insect’s gut. This causes paralysis and death of the larva or pupa. You will need to sprinkle these granules over the surface of the water at a ratio of one tablespoon per 75 sq ft. Choose water features and containers with standing water as it is where mosquitoes breed.
When is it effective? Actually, larvicides are a must for a successful mosquito control program. Since it is easier to kill these insects en masse at the larval stage, you should treat standing water with this solution as soon as the mosquito season starts. Experts from the UC Division of Agriculture and Natural Resources claim that applying larvicides in combination with other preventive measures prevents mosquito infestations in most cases. The insects will be killed within a day after ingesting the toxin.
Why is this product the best? Bti larvicides are also available in the form of liquids and powders, however, granules are considered to be the most convenient and safest option. It works fast, significantly reducing the mosquito population within less than a week. The product does not cause damage to the environment and is safe for humans, pets, bees, and birds.

Fogging may turn out to be more expensive than other approaches because it requires special equipment. Despite this, it is still highly popular among homeowners and there are reasons for that. The device is powered by propane and does not require cords or batteries. It transforms the insecticide into microscopic particles and sprays the fog into the air. The insecticidal particles fall on plants and other exposed surfaces in the yard, killing mosquitoes on contact.
When is it effective? The effect will last for up to six hours, so use it immediately before outdoor events to protect yourself and your guests from mosquito bites. However, the best time for fogging is at dusk. At this time of day, they are most active and flying around searching for food, becoming a perfect target for fogging.
Why is this product the best? It is made by a trusted brand, Black Flag. Foggers like this are used by professionals and are efficient in killing mosquitoes. The trick is that the Burgess produces particles 7 times finer than mist. With this device, you can use 40 ounces of insecticide at a time and treat up to 5,000 square feet in about ten minutes.

This Permethrin-based insecticide is an excellent choice for fogging. Why? Entomologists from Iowa State University note that this ingredient has low toxicity, which makes it a more suitable option for treating lawns and gardens. The other ingredient is Piperonyl butoxide, an organic compound that works by enhancing pesticide potency.
When is it effective? The Black Flag insecticide kills mosquitoes on contact and repels them for about six hours after application. That said, it is safe for people and pets. Just wait five minutes until the fog disperses. Use it to treat large areas because one bottle will be sufficient to cover half an acre of land.
Why is this product the best? This insecticide can be used with most foggers from well-known brands – Burgess, Cutter, Black Flag, Repel. The product will save your time as it comes as a ready-to-use fogging insecticide, meaning you will not need to dilute it in water.

If you are looking for a higher-capacity trap, try this powerful device that operates on propane. Once it is turned on, electronic ignition sparks the tank filled with propane. The fuel is transformed into carbon dioxide, the gas that attracts bloodsuckers as it resembles human breath. The insect is then sucked by a powerful vacuum inside the machine and captured with sticky traps. And this is where the poor guy finds his final resting place.
When is it effective? Use it to cover large areas as the trap protects up to one acre from mosquitoes. While the unit does not kill larvae, it efficiently eliminates flying pests. But make sure that you install it away from where people gather as it will draw insects. Turn it on when the temperature reaches 50°F or two days before an outdoor event.
Why is this product the best? It is significantly more expensive than other popular traps on the market, but it is really worth it. This mosquito-killing machine is nothing short of a beast. It produces at least 25% more carbon dioxide than other models in the same sort of price bracket. Also, the unit is cordless, meaning it can be easily moved around your yard. The manufacturer recommends moving the trap from one pace to another every few days to find the most effective location.

This one-pound pint contains a concentrate of strong insecticide. Mix it with water to make up to 64 gallons of ready-to-use solutions. The active ingredient in this product is Deltamethrin , a synthetic pyrethroid that is safe to humans but is highly toxic to insects and fish. Once digested, the insecticide kills the insect on contact, by damaging their nervous system.
When is it effective? You can use it both as a mosquito killer and as a repellent. For example, one of the most widespread uses of this ingredient is mosquito net treatment. Deltamethrin lasts long and provides an effective solution. Scientists from Duke Global Health Institute stress that bed nets treated with insecticides such as Deltamethrin are an important form of mosquito-caused disease prevention.

One pack includes four tubes containing sucrose (88.34%), yeast (0.18%), and sodium chloride (11.48%). To make it work, you will need to fill each tube with water. The yeast and sucrose produce CO2, which attracts mosquitoes as it is associated with human and animal breathing. Since standing water is their breeding ground, it will serve as a powerful attractant as well. Once in the container, the insect will drink the water mixed with salt and die in a while.
When is it effective? The manufacturer recommends installing the Spartan at the beginning of the mosquito season to obtain better results. It is a perfect choice for those who cannot or do not want to use chemicals in the yard. Keep in mind that proper placement is crucial for the product to be effective. The best locations include shady areas, such as under the trees and in dense vegetation. Hang the tubes on the trees, about 180 feet of each other.
Why is this product the best? This is the most environmentally friendly and safest solution as it includes only natural ingredients. Unlike typical mosquito traps using propane or electricity, this mosquito killer does not require a power source. When compared to plant-based sprays, the Spartan has the advantage of being a longer-term solution as each tube will last for about 90 days. On top of that, the product covers up to one acre, which makes it the best whole-yard solution.

Your fight against mosquitoes has never been so fun! Once you see a mosquito, swing the swatter towards it and the insect will be killed with the electric shock produced by the built-in grid. Charged to a voltage of up to 1500V, the unit is activated by pressing the button. The swatter is over 18 inches in length and has a wide zapping area. With a weight of just 5.4 ounces, it is easy to hold and operate. The device is cordless and comes with AA batteries.
When is it effective? In my view, electric mosquito swatters are a breakthrough in pest control. The most significant downside of other types of bug zappers is their relatively passive action. They may lure an insect or may not. It eventually depends on whether the insect has other attractants nearby. Mosquito swatters eliminate this shortcoming as you do not have to wait until the insect takes a decision. You just swat the bloodsucker, while the electric grid will instantly kill it. You can safely use electric swatter both indoors and outdoors, but not when it is raining as the device is not waterproof. It is a great choice for outdoor activities and a backyard party.
Why is this product the best? This is the most effective electric swatter on the market. Unlike other models, which have three layers, this model comes only with one layer and easily kills insects in one swat. The downside is that its one-layer design makes this bug racket less safe, therefore, make sure you keep it out of children’s reach.

Nematodes are tiny swarms that are widely used in pest control. They do the job by entering the mosquito through its openings, penetrating into the body and releasing toxic bacteria. As a rule, the host dies within 3 days. To apply the parasites, mix then with water and pour the mixture in a sprayer.
When is it effective? These beneficial insects can adapt to nearly any environment and can thrive both in soils and water — be it fresh or marine — and survive in cold and hot climates. Nevertheless, as Edward Platzer from the University of California University of California points out,, nematodes are less effective against mosquitoes at a temperature lower than 69°F. Also, studies have shown that almost half of nematodes infect mosquitoes in freshwaters, whereas higher salt concentrations inhibit infection.
Why is this product the best? This is the safest and most natural way to get rid of mosquito larvae. These nematodes target more than 200 pest species and are sufficient to treat about 4,000 sq. ft. One pack contains 100 million parasites and ice to ensure the high quality of the product.
