Although most of the estimated 800 species of ticks usually live in high grass, forests and overgrown areas, ticks can drop from host animals into your lawn. A female hard tick will feed only once and then drop up to 10,000 eggs. Ticks can carry and transmit diseases through their saliva, making them a potentially dangerous pest in your lawn. Ticks often carry diseases like ehrlichiosis, Lyme disease and Rocky Mountain spotted fever. Although ticks won't harm your lawn itself, they are certainly pests that you don't want around your home. You can get rid of ticks in your lawn using certain repellents and insecticides.
Mow your lawn to remove all tall grass. Rake up any fallen dead leaves and other debris from your yard, because this is where ticks like to hide.
Fill a pump sprayer with a garlic-based mosquito, tick and flea repellent spray, such as Mosquito Barrier. Spray the outside of your house, working your way out to the lawn.
Spray the repellent around areas of standing water in or near your lawn, such as garden ponds. Perform four monthly applications during the tick season, which begins in the warmer spring months and lasts through summer.
Apply a permethrin-based insecticide to your entire lawn area using a hose-end sprayer. Spray from your house out to the lawn as you did with the repellent spray.
Keep all pets, children and people away from the area that you have treated until it's completely dry.
