Ticks carry diseases such as Lyme, monocytic ehrlichiosis and Rocky Mountain spotted fever. Ticks are not insects as many people think. Instead, they are arthropods that need hosts in order to survive and reproduce. To rid your yard of ticks, you must get rid of the hosts or else it will be a losing battle. In the meantime, cover your body with clothing and carefully apply insect spray that contains DEET to your clothing and exposed skin.
Bathe your outdoor animals with an acaricidal soap for pets. This will help kill any ticks on them and help keep the ticks at bay. Put tick and flea collars on your pets.
Rid your yard of unwanted animals. Keep trash can lids on tightly, and install fencing. Remove wood piles where mice and other small animals may be living. Remove bird feeders where squirrels may be feeding, and don't feed wild animals. Plant deer-resistant plants such as dicentra and iris.
Mow the grass frequently and at a height of 3 inches or less.
Cut down brush, and get rid of piles of leaves and other debris. If your yard borders woods, cut down all the underbrush for the first 5 to 10 feet. Then, add a foot-wide gravel or wood chip border between the woods and your yard.
Spray your yard with an acaricide spray. This will kill ticks that are directly hit. Always follow the manufacturer's directions when using a pesticide. Do not allow people or animals to enter the sprayed area until after it dries.
