There is a large mound getting larger on the side of my hill. There are many tiny holes all over it.?

Question

It is not sandy, but covered in grass. I am afraid to disturb it, but it's making me quite nervous as it is about 30' from my house. What could it be? It's about 16" high and 20" in diameter.

Answer 1

sounds like you need to get an exterminator or make a concoction of insect killers. It could potentially be ants or it can be a nest of termites, since they do come from underground.

Answer 2

Ants.
