Mosquito Barrier is a very strong liquid garlic made from very potent garlic cloves. The garlic used in Mosquito Barrier is a very powerful variety which is much more potent than the garlic found in grocery stores (in fact, our lab people here refer to it as "super garlic"). Garlic has a natural sulfur which repels insects, including mosquitoes, ticks, fleas and even black flies. Spraying garlic to keep insects away is not something new, farmers and master gardeners have been doing it for many generations (btw: do you like the smell of pizza?).

Since mosquitoes are soft-bodied insects the garlic juice can be very toxic to them in increased concentrations. The juice does not harm humans or pets or plants, but to mosquitoes it can be deadly. The odor of it chases them out of t e 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 within minutes, the mosquitoes will still detect it. Mosquitoes have extremely sensitive odor sensing antennae - as high as 10,000 times better than humans. They can detect the garlic extract for much longer periods of time and will stay away from the sprayed area for up to a month and more. If the mosquitoes aren't in your yard, they can't get into your house.

Additionally, Mosquito Barrier, when mixed with soybean oil (available at your local grocery store) plus the water, coats any standing water in the area with a very thin film of natural oil, including some garlic oil which is present in the garlic juice. This oil suffocates the mosquito larvae which are developing in any standing water. Mosquito Barrier, unlike harmful chemicals, doesn't kill bees or butterflies and is completely safe for children, fish, birds, dogs, cats and other pets.

Generally, four applications are enough for the entire mosquito and tick season. Even in the heaviest of infestations the gallon size is almost always enough for the entire year for most homes - including areas where the mosquito is the state bird.

Mosquito Barrier is a three pronged attack:

(1) It kills the adult mosquitoes on contact.

(2) The garlic coated plants keep mosquitoes out of the area.

(3) It suffocates any mosquito larvae in standing water, such as puddles, under decks, water in tin cans or depressions in lawn, etc.

Active Ingredients: Garlic juice 99.3%, Citric acid .5%, Potassium sorbate .2%


Professional lawncare specialists using Mosquito Barrier prefer this formula to all others:

If there is NO STANDING WATER in the area use this formula:

Mix 4 ounces of Mosquito Barrier into one gallon of water. Stir well and spray about an hour before sundown.
  • 1 gallon water
  • 4 ounces Mosquito Barrier
If there is STANDING WATER in the area - add a vegetable oil to the mixture using this formula:

For each one gallon of water, add 4 ounces of Mosquito Barrier plus 2 ounces of either Soybean Oil or Canola Oil (found in your local grocery store's cooking oil section) and 1 teaspoon of Ivory liquid soap or any other non-scented liquid soaps (not detergents). Stir well and spray about an hour before sundown (Mosquito Dunks can be thrown into standing water - gard039).

The oil is used to put a coating of oil on the standing water to suffocate mosquito larvae. Soap helps the garlic oil mix well with water.
      • 1 gallon water
      • 4 ounces Mosquito Barrier
      • 2 ounces soybean or canola oil
      • 1 teaspoon liquid soap

Do not spray if it has just rained, or if rain is expected within 24 to 48 hours of application. Apply on a dry lawn and do not run sprinklers for 48 hours after application.

To apply this solution, you can use a Hudson Sprayer available at Greener Country. They typically hold from 2 to 3 gallons of liquid. Canister sprayers must be pumped up with air pressure and they have a wand for spraying. The formula for a 2 gallon canister sprayer is to add 8 ounces of Mosquito Barrier and then fill canister with water. Mix well and spray.

Garden hose-end sprayers are not recommended because they are generally very inaccurate and the droplet size is larger than desired. However, if you insist on using a Garden hose-end sprayer - there are two types, one type has a dial for ounces per gallon and the other does not have a dial. For both types, mix 12 ounces of Mosquito Barrier with 20 ounces of water and use this mixture to completely fill the container. On the dial type, set the dial on 2 ounces per gallon, or 4 tablespoons per gallon. Normally it takes about 7 minutes to empty the container with the garden hose on full blast, so you need to be quick, or fill it again until you have covered everything we recommend.

One gallon of Mosquito Barrier is enough for the whole Summer mosquito season. Sprayed every 3 weeks, for the average half acre residential lot, one gallon is enough for 10 applications, if necessary.

To rid your yard of ticks, see our directions on the FAQs page on this website.

No harmful chemicals, safe around children and pets when used as directed, and is biodegradable.

Mosquito Barrier is patented.

It is important that 8 ounces of Mosquito Barrier be applied to each 6,000 square feet of yard. If you still have some spray material left over after spraying your yard, continuing your spraying until your mixture is completely used up.


1. When mixing (for use on standing water), mix the Mosquito Barrier and soap together and then add it to the water. Stir the entire mixture until homogenous. If you have very hard water, add a bit more soap to make everything mix well.

2. When spraying grass with the wand on the end of your pump-up Hudson pump sprayer, available at Greener Country, hold the wand nozzle about 8 inches above the grass and sweep it back and forth. Make sure the spray gets deep into the grass and use a small spray droplet size.

3. Spray all dark places such as under porches, in vents leading to basement or beneath the house, even spray sides of house, porches, driveways and areas that are not covered with grass - this all helps.

4. So long as you use at least 4 ounces of Mosquito Barrier per gallon of water you are okay. You may use more. Many of our professional spray people use 4 to 6 ounces of garlic per gallon of water. This does not harm plants or animals and works very well.


There are a few things you'll need to know to effectively repel ticks from your yard and around your house. Mosquito Barrier doesn't kill ticks on contact but it does repel them. Ticks are carried into your yard by animals such as deer or squirrels. A tick will "hang out" in tall grass and on tall weeds as well as on fence posts, wood siding on your home or shed and in shrubs and bushes. They like damp places. They will wait for you to brush against the tall grass or shrub and will cling to you. Knowing this, spraying for ticks is much like spraying for Mosquitoes with a few exceptions:

There's no need to spray standing water or the leaves in a tree. Ticks wait for their prey relatively close to the ground. Do make sure you spray the trunk of the tree. Also make sure you spray all wood fence posts in the area. Spray the wood siding on your home up to a height of about 5 or 6 feet from the ground.

You should also spray under porches and in dark, shaded areas (they rest there in heat of the day). Spray grass, shrubs and all greenery. Don't forget to spray woodpiles and re-stack any firewood - where they may be hiding. Keep grass cut and eliminate tall weeds. Try to keep children and pets inside a sprayed, fenced area. After the first spraying, which should be once over and then once over again, repeat spraying in 7 days and thereafter about every 3-4 weeks during tick season.


When you initially spray Mosquito Barrier it kills the mosquitos and chases away the ticks, fleas and gnats. It coats the leaf surface of the grass, ornamentals and lower leaves of the trees with natural sulfur contained in garlic juice and all of these insects, not initially killed, are repelled from the area by this juice. It also prevents entry of any neighboring mosquitoes that may consider wandering in from next door. Mosquito larvae which were in any standing water in the area are now suffocated by the spray which coats the water's surface and prevents oxygen from reaching the larvae. The Mosquito Barrier is odorless to humans, but not to the insects.

A mosquito's sense of smell is about 10,000 times better than yours and they are able to locate humans because they detect the carbon dioxide given off by us. Mosquito Barrier masks the carbon dioxide odor. If they can't find you, they can't bite you and they seek nourishment elsewhere. Another important fact to remember is that mosquitoes are also attracted to bright lights - as are a lot of other early evening or nighttime bugs. No matter what stands between them and the light - they don't care - they go right for the lights. It's always a good idea to turn down the lights in the evening to reduce your chances of being bitten by mosquitoes.

Have you ever wondered why there are no mosquitoes in a garlic field?
