Fire ants build up and out

Fire ants foraging.

Even dry land hasn't been so dry.

It's not your imagination that the fire ant mounds seem to be piling higher. The ants normally dig deep this time of year to ride out the cold. But when it rains, deep doesn't cut it.

"If you ever poured water on an ant hill in your yard, you know that it seems like you're getting rid of them, but they're just going somewhere else," said Laurie Reid, S.C. Forestry Commission entomologist. When rain saturates the ground, they build up and out, she said.
