While you may want your yard to be a tranquil place for kids or pets to play while you prepare meals on the grill or enjoy a morning coffee, mosquitoes and other flying pests can quickly take over a yard, forcing you inside.
Eliminating and preventing these pests can be accomplished with the best mosquito yard spray or fogger. Mosquito yard sprays are designed for concentrated pest extermination, while foggers apply a low volume pesticide or repellent over a larger area, allowing you to treat the entire yard. Beyond the size of the area, the best mosquito solution for a home also can depend on the severity of the infestation. A spray may be easier to use, but a fogger can be refilled as many times as necessary.
This guide includes important factors to consider when deciding on mosquito pest control solutions. Below is a list of some of the top products that can help control mosquito infestations in and around a home. We scoured the market and researched top-rated mosquito yard sprays and foggers in a variety of categories.

Types of Yard Sprays and Foggers
Based on the method used to apply the pesticide and the power source for the fogger, mosquito yard sprays and foggers fall into three categories: spray, electric foggers, and thermal foggers. All three types can be used interchangeably, and many users may have both a fogger and a spray that they turn to when mosquitoes begin to appear.
Sprays are a common option for those who are only dealing with a small infestation, though they also are suitable for more precise targeting alongside a broad-treatment fogger or mister. These products typically contain a concentrated form of pesticide with a range of different active ingredients, each intended to kill mosquitoes and other insects.
These products don’t require premixing or filling like foggers and misters, so spraying the infested area can begin immediately. However, these products are not typically reusable, so they can become more expensive in the long run to treat a recurring pest situation.
Electric (or Cold) Foggers
Foggers are designed to disperse a small amount of pesticide over a broad area, helping to ensure maximum coverage. Electric foggers, also known as cold or nonthermal foggers, utilize a series of swirling nozzles within the machine that separate the pesticide, vaporizing it as high-powered air pressure forces the pesticide out of the fogger. These devices can be used inside or outside, though they typically require a direct connection to a power outlet through a power cord, which limits their mobility.
One clear shortcoming limits their versatility for outdoor applications: the power cord. The motors for these machines operate through a direct connection to a power outlet, so the range of application is impacted unless a portable generator is used. When used near an outlet, these devices are much better equipped for long periods of operation because they run out of fuel only if the power goes out.
Powered by propane or gasoline, thermal foggers have a heating element that heats and vaporizes pesticide as it’s pumped out of the fogger, allowing the vapor droplets to spread across the yard for about 5 to 10 minutes.
Due to the high temperatures produced by this fogger, it isn’t advised to treat indoor insect infestations with a thermal fogger. Commonly used by and sold to professional pest extermination companies, these machines are considered commercial devices that usually carry a high price tag. The machine’s power and cordless versatility allows it to disperse a broad application of pesticide.
These gas-powered machines operate with a finite amount of fuel, so they will need to be refilled regularly to continue working. Also, before storing these foggers for long periods of time, the fuel should be completely emptied.
What to Consider When Choosing the Best Mosquito Yard Spray or Fogger
Mosquito yard sprays are designed to quickly and effectively treat mosquito infestations. However, before deciding on which product is best for treating your mosquito situation, consider the coverage of the treatment, the active ingredients of the pesticide, and a few additional factors that are mentioned below.
The coverage of a spray and a fogger can vary widely because sprays are typically used for precise treatment of a nesting area, while foggers are made for a broad application. Sprays can have coverages ranging from 500 square feet to 5,000 square feet, depending on the amount of spray in the bottle and the dispersal system.
Foggers make it easier to apply a pesticide over a broad area. This allows the entire yard to be treated within an hour, instead of the user having to walk around with a small spray bottle. Foggers can extend from about 5,000 square feet to more than 30,000 square feet, depending on the size of the fogger, the range of the power cord or fuel, and the amount of pesticide.
After dispersal, it takes between 5 and 10 minutes for the fine mist to settle, so it’s important to use breathing protection to avoid inhaling airborne pesticide droplets.
There are many different active ingredients used in mosquito yard sprays and in the pesticides loaded into foggers. These include sodium lauryl sulfate, lambda-cyhalothrin, gamma-cyhalothrin, permethrin, and various essential oils.
- Sodium lauryl sulfate is a common ingredient in shampoo and detergent, so there isn’t a concern about dangers to pets and kids. However, it’s still a powerful insecticide that kills mosquito larvae and is effective against spiders, gnats, ants, and yellow jackets.
- Lambda-cyhalothrin is a synthetic pyrethroid derived from pyrethrin, which is a naturally occurring insecticide present in chrysanthemums. This active ingredient kills both adults and larvae, quickly preventing infestations.
- Gamma-cyhalothrin is another common synthetic pyrethroid that attacks the central nervous system of adult and larval mosquitoes, destroying the problem at the source while treating the ongoing infestation.
- Permethrin is a synthetic pyrethroid, though it isn’t as potent as the other two pyrethroids listed. Permethrin is actually more frequently found in repellent products than in pesticides, due to its lower level of toxicity. However, in high enough concentrations, permethrin will act in the same way as other pyrethroids, killing mosquito adults and larvae.
- Essential oils, like peppermint, lemongrass, citronella, and cedar oil, are natural alternatives to chemically based synthetic pyrethroids. In high enough concentrations, these oils act as powerful deterrents to mosquitoes and will kill both adult and larval mosquitoes. The oils are relatively safe for homes with kids and pets, though these natural pesticides are not as effective and do not usually last as long as chemical solutions.
Fuel Type (If Applicable)
Thermal foggers can use propane, gasoline, or a mixture of gas and oil that is similar to the mixture used in gas lawn mowers or string trimmers.
- Propane-operated foggers are equipped with a port to connect a portable propane tank, like those used for portable propane grills. There isn’t a lot of potential power difference between propane and gasoline, but the ready-to-use compact propane tanks can be simpler.
- Gasoline-operated foggers have a gas tank that needs to be filled before the fogger will operate. After use, it’s advised to empty the tank before storing it for an extended period. While there are more steps involved in setting up and filling this style of fogger, money can be saved on bulk gasoline purchases.
- Gas and oil mixtures are common with larger gas-operated tools and appliances. By incorporating the oil into the gasoline, the entire system can be properly lubricated every time the gas tank is filled and the fogger is operated. The drawback with these machines is that it takes time and effort to properly mix the gas to oil ratio before the fogger can be filled. If you are regularly in a hurry to complete tasks, this may not be the best option.
Ease of Use
It’s a good idea to look for mosquito yard sprays and foggers that come with features that make them easier to use, like adjustable nozzles, backpack straps, and wide-mouth tank openings.
- Hose attachments (especially when combined with a pre-mixed solution) on yard sprays can simplify the application process by removing prep from the equation and delivering the exact amount of mosquito spray necessary.
- Adjustable nozzles allow the user to change the spray density of the fogger or spray can so the amount of pesticide being applied can be increased or decreased. Some products have built-in adjustable nozzles, while others may use interchangeable nozzles to achieve the same results.
- Backpack straps are ideal for carrying a heavy fogger, especially if the user will be treating a large area. The straps allow users to support the weight of the fogger with their entire body, reducing muscle strain and fatigue that can be caused by trying to carry and operate a device that can weigh more than 40 pounds.
- Wide-mouth tank openings are a simple feature that can save time and money. Foggers need to be filled with a pesticide, so a wide-mouth opening makes it easier to quickly fill the tank. It also makes spills less likely so users aren’t wasting the pesticide or making a mess.
Safety is a priority whenever dangerous chemicals or machines are involved to ensure that a job can be completed without putting anyone at risk. With this in mind, it’s important to always read and follow the directions for use listed in the product information, on the product container, and on the manufacturer’s website.
Chemical pesticides can cause adverse symptoms including irritated eyes, rashes, dizziness, nausea, diarrhea, headaches, shortness of breath, and vomiting. It’s necessary to wear proper eye and breathing protection, and it isn’t a bad idea to wear gloves, long pants, and a shirt with long sleeves as well. Usually, it’s recommended to wait at least 30 minutes to 2 hours—or longer—before using an area that was sprayed.
