Looking for something organic to get rid of caterpillars (cabbage white). We planted about 40 cabbages at various ages and put collars round, still lost four to cabbage root fly. We then made a cage of one centemetre square mesh bhut this week we now have the Bl***y caterpillars on the cabbages. I am squemish and dont like squashing them, as a child I had no problem and I used to jump on them oh how times change.
We have looked on the internet and found something called Dipel and or garlic spray.
Has anyone else used this method to treat cabbage white caterpillars.
We only have three days to treat the cabbages before we are away and the "the lunatics take over the asylum"

Any suggestions as we dont have anyone to check daily that there are any caterpillars.
