Gardeners have used homemade garlic mixtures to fight insects for centuries. Garlic Barrier is a product that takes that home concept and improved it by identifying the strongest variety of garlic and by growing it in soils with just the right minerals to make it as potent as possible. When the Garlic Barrier spray is applied to many plants and crops, most pest insects and most pest animals are repelled by the garlic smell and move on to someplace else. If the insect or animal actually takes a bite of a plant, the Garlic Barrier’s taste is just as fearsome.
Garlic Barrier will kill some insects but it is primarily a repellent
It is effective by being able to prevent a pest insect or pest animal from even approaching many of the plants in your landscape. It is the repelling function of this product that we will focus on in this file.
Garlic Barrier, when used on lawns against mosquitoes, actually kills the mosquito larvae. There is no evidence that it kills the adult mosquito at this point, but it repels them.
