No season, purely vermin/pests. One rancher we shoot for runs 600 head of cattle by himself and has no time to deal with his pests, one quarter section last year we cleared about 700 gophers so its good for a few years, couldn't find anymore. Another quarter had my best guess of about 4000 and we shot it all summer and it seemed like we only got half. Badger holes 10' in every direction and the gopher holes you couldn't begin to count...swiss ground(as opposed to swiss cheese). That one quarter is about as nasty as it can get...then in late spring there's a whole new batch of the young which average about 5 per female! So if you really want to do the best work you gotta deal with as many as possible before the young come...even then its like you hadn't done a dang thing. It always pleases the pc/ethics folks to know that they don't just go to waste either. The birds get most, magpies, crows, ravens, hawks and even eagles will land in the fields to eat the dead. The rest get cleaned up overnight by the coyotes and badgers. In 24 hours that pile of gophers was gone believe it or not, not even so much as a blood stain was left on the ground as we went back the next day to shoot. Even i was amazed at that.
