I am new to Pierce County and have discovered many ant mounds on and around our 5-acre property and the entire community. The area is dense with primarily Douglas Fir trees. I have identified the ants as thatching ants (black body, red head, medium size...not a "small" ant but not as large as a carpenter ant). They do bite. I see trails going from trees to their mounds made of tree needles. I know there are a bazillion miles of underground trails and a kazallion number of above ground ants. Ants are beneficial, but I can't have them biting anyone walking around our property or lazing on lawn chairs. Do I co-exist with them, try to move their mounds, or...? I don't think an exterminator would work because wouldn't they simply rebuild their mounds and maybe rebuild closer to our house? I know chickens will eat them, but there are simply too many ants unless I had 20 or more chickens that continually ate them. Chickens are what they eat and I'm not sure I'd like that taste after I harvest one. Help.
