Exotic ticks appear to be establishing themselves in Alaska

While Alaskans have long endured dense mosquitoes and frigid air, we’ve always had the absence of venomous snakes and dog ticks.

But the latter may be establishing themselves here. Ticks that infest red squirrels, snowshoe hares and a variety of birds have always been present in Alaska, but a team of biologists and veterinarians recently found five non-native ticks on Alaska dogs and people.

In a recent study published in the Journal of Medical Entomology, researchers identified brown dog ticks, American dog ticks, Rocky Mountain wood ticks, deer ticks and Lone Star ticks in Alaska. A few of those creatures hitchhiked up on animals and humans that had recently visited the Lower 48. But some had not.
