It's really just a probability thing.
And another factor is in the ticks themselves, right?
The animals that they feed on and the way they get to them is different.
In a number of studies that Jean and her colleagues worked on, they found that ticks in the north tend to feed on small mammals.
So birds, rodents like squirrels and mice and chipmunks, as well as humans.
And ticks in the South tend to look for hosts on the ground, below the layers of leaves on the forest floor.
So sometimes birds, but more often reptiles, like lizards.
Andrea Sway, who's the researcher that you heard at the beginning, says this is true of her California ticks as well.
They seem to prefer lizards.
And this is really important because it turns out some of these lizards have a superpower.
They can clear the ticks' systems of Lyme disease.
That's so cool.
Yeah.
So back in the 1990s, a group of researchers looked at a key host for ticks on the West Coast, the western fence lizard.
And they discovered that after feeding on this lizard, even previously infected ticks would become Lyme-free.
Later studies found a specific protein in the lizard's blood that killed the Lyme disease bacteria, Borrelia burgdorferi, completely.
Wiped it out.
Cured the ticks.
Cool.
And Dina, get this.
