1. Ground Squirrels Climb Trees
They don't spend as much time in trees as Tree Squirrels do, but they do run up trees to escape predators. Ground Squirrels also strip the bark of of young trees and eat fruit and nuts.
2. One Acre of Land Can Be Home to 100 Squirrels
It's like an over-populated underground squirrel city! Imagine all of the burrows and holes - and rodents! Large populations of ground squirrels lead to disease, erosion, and their holes are a dangerous liability.
3. Ground Squirrels are Cannibals
They are not vegans. A small part of their diet is cannibalizing their own kind, and eating road kill. Quail and pheasant eggs are also on their menu.
5. You Can't Trap & Release
California Fish and Game Code specifies it is illegal to release ground squirrels elsewhere without a written permit. That means, even though you treat the ground squirrel problem on your land and squirrels keep invading from your neighbor's property, you cannot trap them and return them to your neighbor's side of the fence. It also means that you can't drop off trapped ground squirrels at a nice park or school. (People actually do this!)
Another option is visiting me in person. If you need California DPR continuing education units, I'll be speaking at the upcoming PAPA Seminars:
