There are mound after mound of these red ants on the sandy soiled hillsides in my area. In fact some of these ants are right in my front yard! Today I walked up Sheep Hill, which is due west of my house. The top of the hill has a lot of disturbed soil, with White Pines thriving. I saw many of these red ant mounds. The camera is alittle shaky because I couldn't stand in one place without the ants crawling on to my boots. I'm thinking a person, or animal could be quickly covered by ants in a matter of seconds if they stood even close to these ant hills. THAT is creepy! I didn't hang around long enough to see if they would bite, but I assume they would.
Ant bites not only hurt but if you have a tendency to be allergic to insect bites, these buggers will make you itch, and may even leave a scar.
