Fuck that OP, get a Hitachi Magic Wand, attach it to a metal stake, ram that stake into the ground (the earth is a dirty slut, she wants it) and shock & awe those little burrowing rodents

Your circuit is notorious for touchiness.
Most of the time it will work but if you change the load usually it will fuck up.
Try simulating it, I have never seen it simulated first time because it relies on imperfections.
An alternative would be a 555 timer circuit.
If you want to learn build both. If you just want your problem solved then don't build either because your plan is insane.
In theory the supply voltage would match whatever motor you used however if it draws too much current you will need a driver like a transistor or something, maybe a relay too at which point the motor voltage can be different

Great idea. You should simulate it first and learn a little bit more about the species of mole that lives in your area and you should be fine.

I must be fucking retarded because I don't know what the fuck any of that means
