I like a barrier with hardward cloth or traps. We could never get a trap to work.

There is one killer I would consider possibly, but didn't at the last minute. There is one that has a gas. The first critter that gets it is the one that dies. That could be a bird or pet. However, once the first critter dies, later ones could safely eat the first critter and be ok. The gas poison kills and goes away. (I called the company and asked specifically.)

If I had a large area to prepare, I would try to dig a trench around it, 12 inches deep, put in hardware cloth, and possibly run it across in certain places. The vole would not go that deep. If, by chance it went down from above, it would be stopped by the next barrier.

I don't know what one does in a large field.

We put hardware cloth around individual roses. Others put in large pots full of holes, and plant in them.

We have a creek behind our house, so we will always have critters.

Moles are the pitts. I have bought many boxes of Gopher Gas, and even screwed a 1/2" pipe into my lawn mower exhaust to gas them. All that I am sure of was burning the exhaust valve out of my mower. If I killed any it was not enough to miss.

Coons are never a problem since i have a 70 lb catahoula... bugs i fought last year and know how to win that battle but i have a 100x100 patch planned this year and we do our first till with the tractor and big 7 ft tiller and i would not be that upset but i want a huge crop and i know if the moles get to it bye bye.. And the dogs will kill the moles BUT then i will have huge holes in the garden and more damage..

i guess i could put those poisin stakes in the ground all the way around the garden? Hmmm

its a delema for sure!
