You left out their specialty: POISON IVY.
Park services in this area use them to clear out poison ivy without using an herbicide that kills everything.
I have heard that they also enjoy kudzu.
That’s true. They do eat Poison Ivy as well.
I recall when Round-Up came on the market. Amazing. It seemed almost too good to be true. Turns out it was, too much collateral damage to other plant life, and contamination of the soils.
Sigh!...Sometimes you just can’t have Nice Things!
