Why Are Ticks So Bad in St. Louis This Year?

If it feels like ticks are everywhere in St. Louis this summer, there’s actual science to support that notion.

In April 2026, experts from University of Missouri reported that changes in weather patterns are responsible for creating more favorable conditions for tick survival. And ticks have took full advantage.

Winters are warmer. Springtime weather comes earlier each year. Humidity followed March and April showers in 2026. All these things make life better for pest populations and ticks are no different. This year gave St. Louis ticks a notable head start.

Warm St. Louis Spring Means Early Tick Activity

Missouri’s late-winter and early-spring temperatures were well above average in 2026 – here in Greater st. Louis and across the entire state. This March was the fourth warmest ever recorded. When temperatures increase above 45°F, ticks might begin seeking hosts – much sooner than you might expect tick activity in St. Louis.

Springtime rains provided ample moisture and paired with warm temperatures to create ideal tick conditions around wooded edges, among brush and ground litter, along fence lines, and other areas of vegetation. Those types of tick habitats can be found across the Greater St. Louis area, which has resulted in a notable increase in ticks in 2026.

Missouri Ticks Have Moved Beyond the Woods

You no longer have to go backpacking or camping to encounter ticks in Missouri. Wildlife moves through neighborhoods. Deer often enter residential properties. Dogs and cats explore along fences and shrubs. People work in gardens and spend evenings outdoors.

Ticks move where their hosts move – but are often left behind when the hosts move on. If deer, rodents, and other wildlife move through your yard, they are apt to leave ticks in their wake.

This doesn’t bode well for Greater St. Louis residents.

From lone star ticks to blacklegged ticks and American dog ticks, all pose potential negative health consequences to families and pets, including Lyme disease and alpha-gal syndrome.

Fight St. Louis Ticks Where They Hide

There are a few ways you can fight back. Keeping yards tidy by moving and reducing leaf litter are part of a more comprehensive tick prevention strategy. It’s also wise to perform regular tick checks on yourself, your kids, and your pets after spending time outdoors.
