There are over 800 kinds of ticks, and one or more varieties could be living in your yard or lawn, where they are waiting for a host to come by. When it does, they grab on and use that host, whether it be an animal or person, to feed upon its blood and lay their eggs. Some ticks carry diseases, the most notable being Lyme disease. If you find a tick in your lawn, or it attaches to you or another host after being in your lawn, it is best to take care of the problem immediately.
Put on protective clothing. Wear a long-sleeve shirt, long pants and a hat. Tuck your pants into your socks and your shirt into your pants.
Apply insect repellent to your skin and clothing. Use one that contains DEET on exposed skin and one that contains permerthin on your clothing. Always follow the instructions on the label for proper application. Usually, insect repellents come in a spray form, but some come in a lotion that you rub into the skin.
Test to see if ticks are infesting your lawn. Take a large flannel fabric and drag it across your yard. The ticks will adhere to the fabric when it goes by. If many ticks are present, treating your yard for ticks may be the right choice. If there are little to no ticks on the fabric, perhaps the tick you saw was an isolated incident.
Apply a liquid pesticide labeled to kill ticks, such as one that contains the active ingredient permethrin, in large sweeping motions to your lawn. Liquid pesticides usually only kill adult ticks out in the open, but they can kill some ticks, such as deer ticks, that are still nymph or larvae stage.
Apply a granular pesticide, such as one with the active ingredient bifenthrin, to kill ticks that are hatching or waiting out the winter in your yard. Wear chemical-proof gloves and spread the granules over your yard with a spreader, such as a drop spreader.
