Keep mosquitoes out of your yard and away from your home for nearly a month with just one spraying of all natural, liquid garlic-based Mosquito Barrier®. Mosquitoes can't tolerate garlic - that's why there are no mosquitoes in a garlic field. It can be applied with with just about any pump-up sprayer.

Mosquito Barrier® is a very strong liquid garlic made from very potent garlic cloves. The garlic used is more potent than garlic found in grocery stores. Garlic has a natural sulfur which repels mosquitoes.

Since mosquitoes are soft-bodied insects, the garlic juice can be toxic in increased concentrations. The juice does not harm humans, pets or plants, but can be deadly to mosquitoes. Garlic odor chases them away. The odor of sprayed garlic juice becomes undetectable to humans within minutes, but mosquitoes can detect odor as much as 10,000 times better than a human. So even though you can't smell the garlic, they can and they will stay away for up to a month or longer.

Additionally, Mosquito Barrier®, when mixed with canola oil (available at your local grocery store) plus water, coats any standing water in the area with a very thin film of natural oil. This oil suffocates the mosquito larvae which can develop in standing water. Unlike harmful chemicals, Mosquito Barrier® is a natural insect repellent that 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 season. Even in the heaviest of infestations, the gallon size is almost always enough for the entire year for most homes.

Three Pronged Attack:

  1. Kills the adult mosquitoes
  2. Garlic coated plants keep mosquitoes out of the area
  3. Suffocates any mosquito larvae in standing water

This gallon size jug is best for homes on a half acre for the entire season. One gallon covers 5 acres. 99.3% pure garlic extract.

      • 1 gallon water
      • 4 oz Mosquito Barrier®
