The organic way to tell biting insects to buzz off!

Learn more about our Mosquitos Barrier

Is Mosquito Barrier safe for my children and pets?

Yes! There are no poisons or harmful chemicals. It's just 99.3% garlic juice with some food grade preservatives added.

Will my yard stink like garlic?

A few minutes after being sprayed, the garlic odor becomes undetectable to humans.

Does it repel fleas, ticks and chiggers?


Is Mosquito Barrier harmful to birds or good bugs like bees, ladybugs and butterflies?

No, not at all. Birds, bees, butterflies and ladybugs are not bothered or repelled by the garlic spray. To be safe, we avoid spraying directly onto butterflies.

Will animals be able to eat treated grass?


How long does a treatment last?

It depends on the weather and insect infestation. Typically, a treatment will last 3-4 weeks. Heavy rainfall and high insect infestations may require more frequent treatments. If there is a heavy infestation at the time of the first treatment, we may need to repeat in 7 days and then every 3-4 weeks thereafter.

What else can I do to keep mosquitoes out of my home and garden?

Help reduce the number of mosquitoes in outdoor areas by draining standing water. This will reduce the number of places mosquitoes can lay their eggs. At least once or twice a week, empty water from flowerpots, pet food and water dishes, birdbaths, swimming pool covers, buckets, barrels, and cans. Check for clogged rain gutters and clean them out. Remove discarded tires and other items that can collect water.

Put up a bat house. Bats are a welcome ally to combat mosquitoes and other insect pests. They work while we sleep, eating up to 600 mosquitoes and other night flying insects like cucumber beetles, June bugs, stinkbugs, leafhoppers, and moths in just one hour. Providing them a home on your property during the day will benefit them as well as everyone around you.

Insect repellents used on our bodies play an incredibly important role in helping prevent mosquito-borne disease. Researchers studying the toxicity of DEET have found that it inhibits the activity of a key central nervous system enzyme, acetycholinesterase, not only in insects but in mammals, too. Scientists report it to be a neurotoxin. Our EcoCoaches use oil of lemon eucalyptus (Cutter® or Repel® Lemon Eucalyptus Insect Repellent) while we care for your home and garden.

What else can Squeaky Green Organics do to help reduce the number of mosquitoes in my yard?

If you have a water feature such as a pond, we can apply Bacillus thuringienis (Bt), a bacterium that infect and kill mosquito larvae. These bacteria are highly selective, killing only mosquitoes and do not harm other insects, fish, birds, worms or mammals.

Another organic product that kills mosquito larvae is spinosad, which is derived from a naturally occurring soil bacterium. Like Bt, spinosad does not significantly affect beneficial organisms including ladybugs, green lacewings, minute pirate bugs, and predatory mites. However, it is toxic to bees for the first three hours after it has been sprayed. So we use this product very selectively and avoid spraying it on nectar- or pollen-producing plants. Spinosad is also toxic to aquatic invertebrates so it cannot be used in fishponds.

Bt and Spinosad are listed by the Organic Materials Review Institute (OMRI) as acceptable for use during organic farming and gardening.

Keep away mosquitoes and other insects organically

Repel mosquitoes, including the ones that may carry West Nile Virus and other mosquito-borne diseases. Take back your yard, remove your shoes, and stroll bare foot in the grass all summer.

We use a unique formulation of powerful garlic extracts that repel even the most stubborn of biting insects. When sprayed on lawns, gardens and landscaping it repels mosquitoes, ticks, fleas, black flies and certain harmful garden insects like aphids. It does not, however, harm humans, pets, plants or beneficial insects such as honeybees, ladybugs and butterflies. Sorry, we cannot guarantee our garlic formula will repel vampires.

We know what you're thinking: "I don't want my yard stinking like garlic!" Don't worry, the garlic odor is undetectable to humans within 30 minutes after being sprayed. Mosquitoes have extremely sensitive odor sensing antennae, as much as 10,000 times more sensitive than a human's sense of smell. So, while the odor of sprayed garlic juice becomes undetectable to humans, the mosquitoes still detect the garlic for up to a month! Generally, four applications are enough for the entire mosquito and tick season. At Squeaky Green Organics, we believe in full disclosure, so below you'll find detailed information about the garlic formulation.

The cost for four treatments is $0.04 per square foot. Call 402-575-7988 or request a quote and get more information about the organic way to keep away mosquitoes and other insects.

What's in It

The variety of garlic used in this formula is unique and much more potent than regular cooking garlic. It was selected for its super high concentration of allicin and sulfur-containing compounds. It is believed that the pungent smell of garlic overwhelms the mosquito's sense of smell and prevents them from finding us.

garlic juice 99.3%
citric acid from corn 0.5%
potassium sorbate to preserve freshness 0.2%
Total 100.0%

This product is approved by the Organic Materials Review Institute (OMRI) as acceptable for use during organic farming and gardening. OMRI is a national nonprofit organization that determines which products conform to the rules of organic production and processing. OMRI Listed - or approved - products may be used on operations that are certified organic under the USDA National Organic Program.

What's NOT in it:

Synthetic insecticides. Insecticides such as malathion (an organophosphate) and synthetic pyrethroids that indiscriminately kill beneficial insects such as honeybees, ladybugs, and butterflies. Pyrethroids are also toxic to fish. Since there's no DEET in this formula, it's safe for children, pets, and expecting mothers.

If you are looking for an insect repellent to spray on your body, consider oil of lemon eucalyptus as an alternative to DEET. Endorsed by the CDC, oil of lemon eucalyptus is available under the Repel® brand name and offers protection similar to low concentrations of DEET.

How it Works

The juice does not harm humans, pets, plants or beneficial insects such as bees, ladybugs and butterflies. But to mosquitoes, it can be deadly. It coats the leaf surface of the grass, ornamentals and lower leaves of the trees with the natural sulfur contained in garlic juice. The odor chases biting insects out of the area and they stay away for as long as they can detect the odor. While the odor of sprayed garlic juice becomes undetectable to humans a few minutes after application, mosquitoes will still detect it for weeks. That's because mosquitoes have extremely sensitive odor-sensing antennae. They can detect the garlic extract for much longer periods of time and will stay away from the sprayed area 24 hours a day for up to a month.

It's not clear why garlic is an effective mosquito repellent. Some believe the strong smell of garlic overwhelms the mosquito's sense of smell and prevents them from finding their prey (us). Whatever the mechanism, garlic's ability to repel a variety of pests has been proven scientifically.

When is it applied

The first treatment should occur when mosquitoes start to show up, typically in late May. Treatments are repeated every 3-4 weeks until September, or as requested. If there is a heavy infestation at the time of the first treatment, we may need to repeat in 7 days and then again every 3-4 weeks thereafter.

Where is it applied

We spray liberally on grass, shrubs, plants and tree trunks in the yard.

We also spray the siding on your home and perimeter wood/vinyl fencing up to a height of about 4 feet. The product does not leave a stain.
