We use a .22LR. This one was particularly savvy - an older female, her fur was even turning grey. You could only slide open the slider a bit she had to turn her back to you for you to get a shot. Whenever she came out of the brush she watched the house. Hubby finally got her when her back was turned. About an hour later the smaller one came out and was looking for mama. The small ones this time of year are either the young or males, which are quite a bit smaller than the females. This year I planted no green beans which has been their favorite. She still bothered the broccoli and lettuce but we foiled her early on with collars and chicken wire covers.
I have one, but we are in a cul-de-sac unfortunately. So eighbors o ly 10 orzo feet awY we have to use a quiet tool to rid the critters. Yep woodchuck are very very hard to get. Any little noise or movement and they are gone. I had to put a tarp on our deck railing that I could duck down behind just to get out the door and over to where I could get a chance to see the wiley creature.
We tried havahart traps, but nope, they will not go in. No matter what bait we used
Now I think we have a rat in the garden. My eyes aren’t quite good enough to see them fro a distance though
