hi crinkle, For myself ….yes the snails are a problem. Here is how I see it…
#snails are not what is meant to be growing in the farm
#snails are a pain in the arse when it comes to gardens
#snails need to go.
So what I’d do is the following……
With the feed tray that all the food is being dumped into…..tip it onto a table (not in the sun) and sort through it and remove snails, food and crap until only worms are left on the table……or pick through it all in little piles and remove worms.
Do the same with the other trays….. then start the worm farm off fresh with a coca coir soaked in water for their bedding…….
Sound too hard???? Not really…done this a few times in my 9 years worm farming…when ants had raided a farm. Not hard…just time consuming.
Then pick out as many snails as you can and add the worm farm contents to your garden….. cover it though with soil as the sun will leach out the goodness from the worm castings.
Snail either feed to chooks or bin and removed on garbage day.
Hope this helps.:)
Any questions???? Just as away.
