I found this website and thought it was slightly amusing.
Urban IPM: Rodents: Ground Squirrels and Chipmunks
the top is pretty boring (animal descriptions, etc.), however, the bottom is kinda funny. the elaborate trapping devices, etc.
"No effective ground squirrel or chipmunks frightening methods are available." - Ha! I beg to differ.
"Truck-mounted, vacuum devices that suck rodents out of their burrows have not shown sufficient efficacy to justify their use." -Ok, that just sounds funny. The thought of a big rodent vacuum. Ha! Whooump! Hahahaha!
Alright, enough of that.
