Tick season varies depending on the region and climate, but generally, it is during the warmer months when people spend more time outdoors. The peak tick season varies by species and location, but it is typically from spring through fall.
Ticks are most active when temperatures are above 45°F (7°C) and less than 90°F (32°C). During these months, ticks are most prevalent, and people are more likely to encounter them. In some regions, ticks can be active year-round, depending on the climate.
In the United States, the peak tick season can vary depending on the region. In the Northeast, mid-Atlantic, and upper Midwest regions, tick season is typically from April through October. In the southern states, tick season can be year-round, but it is most active during the warmer months from April through September. In the western states, tick season typically starts in the spring and lasts through the summer and fall months.
Tick species also vary by region, and some species are more active during certain times of the year. For example, the black-legged tick, which is a carrier of Lyme disease, is most active from May through July in the northeastern and upper Midwest regions. The lone star tick, which can transmit ehrlichiosis, is most active in the southeastern and eastern United States from March through September.
