The lone star tick has been making headlines across the country because of a link to a rare allergy called Alpha-Gal Syndrome (AGS). But what does that mean for Fort Collins residents? While the lone star tick isn't currently considered widespread in Colorado, occasional sightings have been reported, typically brought in by migrating animals or birds. The good news is that you can take steps now to help reduce your exposure, and Mosquito Squad of Fort Collins is ready to help.

What Is the Lone Star Tick?

If you spot a tick with a single white dot on its back, you've likely met a lone star tick. This tick is different from other species in one key way: it won’t wait around for a feast to come. Instead, it actively hunts for a host, and humans are a favorite target. Found mostly in warm, wooded, or brush-filled areas, the lone star tick hasn’t yet established itself in Colorado, but it has made a few appearances.

Why Is the Lone Star Tick a Concern?

The buzz around lone star ticks largely stems from their connection to Alpha-Gal Syndrome, a condition that can cause a delayed allergic reaction to mammal-based products like red meat and dairy. Symptoms of AGS can range from hives and digestive issues to severe anaphylaxis. The allergic reaction usually occurs several hours after consumption. Those who are affected will need to make significant lifestyle changes.

But AGS isn’t the only illness linked to the lone star tick. Other serious tick-borne diseases associated with this species include:

Ehrlichiosis – This infection affects both humans and pets and can result in flu-like symptoms, including fatigue, fever, and muscle aches. Dogs, especially those in boarding or kennel environments, may be particularly vulnerable.
Tularemia – Often called "rabbit fever," this bacterial illness affects a variety of animals and humans. Symptoms may include ulcers, swollen glands, and fever.

Are There Lone Star Ticks in Fort Collins?

Historically, lone star ticks have been concentrated in the southeastern U.S., but shifts in climate and increased mobility among wildlife have expanded their potential range. While Fort Collins hasn't experienced widespread infestations, the occasional presence of lone star ticks has been confirmed. That means residents should stay alert, especially those who spend time hiking, gardening, or enjoying natural green spaces.

Should I Be Concerned About Other Tick Species in Fort Collins?

Coloradans are vulnerable to multiple tick-borne diseases, and the following species thrive here:

Rocky Mountain Wood Tick: Colorado Tick Fever, a disease unique to the state, is spread by this species. The virus causes fatigue, body aches, and fever that can come and go in waves.
Deer Tick (Blacklegged Tick): Though relatively uncommon in Colorado, deer ticks are still present in some areas. The species spreads Lyme disease, the most common tick-borne disease in the United States.
American Dog Tick: This species is found in grassy areas and is known to transmit both tularemia and Rocky Mountain Spotted Fever.
