Mosquitoes are discouraged from occupying a grassy recreational area by spraying dilute garlic juice on grass, shrubs and trees. Surprisingly, this treatment repels mosquitoes. More surprisingly, mosquitoes are repelled for many months. For reasons not wholly understood, mosquitoes are repelled by some component of garlic juice which may not be the odoriferous compounds. The equivalent of at least about .04 gallons of full strength garlic juice per acre is applied. Preferably, the garlic juice is applied in a concentration in the range of .04-.5 gallons of full strength garlic juice per acre and in a strength of 1/2-5% garlic juice.
