planting green beans again

My garden was invaded by snails. They comes in variety. big, small and medium size. I can easily see ten of them at one place. All my vegetables was eaten and damaged by this pest!

All my seedling were gone in a night. I planted 15 green beans seedling but only left is 2 green beans climbing on the trellis.

After putting so much effort like salt, egg shell, etc....nothing work out. Finally with advice from nursery guy, I put snail poison. The next morning I found about 60++ of them death! I feel very guilty but I have no choice...... I think the soil I bought from the nursery might have contain a lot of snail eggs........ phew.....

Here is the 2 green beans....climbing safely at the moment.....
