As mosquito season approaches, controlling mosquitoes in yards is a top priority for many homeowners. After all, mosquitoes can be more than just annoying—they can pose health risks due to the diseases they carry. One potential method for controlling mosquitoes in your yard is the use of a garlic barrier. But does it work? And what other methods can you use to reduce mosquitoes in your yard?

Understanding Garlic Barrier

A garlic barrier is a natural mosquito repellent made from concentrated garlic extract. The theory behind its effectiveness is based on the idea that the strong odour of garlic can repel mosquitoes. The active compounds in garlic, such as allicin, are believed to interfere with mosquitoes’ sensory perception, deterring them from entering an area where the barrier has been applied.

Does Garlic Barrier Work?

The effectiveness of garlic barrier in controlling mosquitoes is somewhat debated. While there are anecdotal reports from homeowners who claim it works well, scientific evidence supporting its efficacy is limited. Some studies have shown that garlic can act as a natural repellent, but its effects may be short-lived, especially in outdoor environments where the barrier can be washed away by rain or irrigation.

Additionally, the application of a garlic barrier can be time-consuming and may require frequent reapplication to maintain its effectiveness. The smell of garlic can also be strong, which might be off-putting to some people.

At GreenLeaf Pest Control in Toronto, we use a three pronged approach to mosquito control. Garlic Barrier as a natural repellant, Health Canada registered pesticide for quick kill and specialized mosquito traps to target egg-laying female mosquitoes by replicating breeding sites.

Alternative Methods for Reducing Mosquitoes

If you’re looking for ways to reduce mosquitoes in your yard, there are several alternative methods you can consider:

Eliminate Standing Water:

Mosquitoes breed in standing water, so removing sources of stagnant water is crucial. This includes emptying containers, cleaning gutters, and covering rain barrels.

Use Mosquito-Repelling Plants:

Certain plants, such as citronella, lavender, and marigold, are known for their mosquito-repelling properties. Planting these around your yard can help keep mosquitoes at bay.

Install Screens and Netting:

Use screens on windows and doors to prevent mosquitoes from entering your home. Outdoor seating areas can be protected with mosquito netting.

Use Mosquito Traps:

Various types of mosquito traps are available on the market, including those that use light, heat, or CO2 to attract mosquitoes. These traps can help reduce the mosquito population in your yard.

Apply Insect Repellent:

When spending time outdoors, applying insect repellent containing DEET, picaridin, or other approved active ingredients can help protect you from mosquito bites. Always follow the label of the product before applying.

Keep Your Yard Tidy:

Mosquitoes can hide in tall grass and overgrown vegetation, so keeping your yard well-maintained can reduce hiding spots.

Install Fans:

Mosquitoes are weak fliers, so installing outdoor fans can create a breeze that makes it difficult for them to fly and bite.

Consider Professional Treatments:

If you’re struggling with a severe mosquito infestation, you may want to consider professional mosquito control treatments. These services can apply targeted treatments to reduce the mosquito population in your yard. Consider GreenLeaf’s triple threat program for mosquito control in Toronto to maximize your summer fun.


While a garlic barrier may provide some level of mosquito control, its effectiveness may vary and may not be the most reliable method for managing mosquitoes in your yard. Instead, a combination of alternative methods such as eliminating standing water, using mosquito-repelling plants, and maintaining your yard can help create a less attractive environment for mosquitoes. By taking a proactive approach and employing multiple strategies, you can enjoy your outdoor space with fewer mosquito interruptions.
