Spring is an appropriate time for tick education. Ticks may be active all year long if temperatures outside are above freezing, but May and June are the months when people pick up the most ticks. There are three tick species established in Nebraska that carry and spread diseases to humans and animals, including the lone star tick. Lone star ticks are widely distributed across the East, South and Central United States, extending across the southeastern portion of Nebraska (see figures at the end of the article).
