The snails have been drowned in the beer traps. I now notice white
butterflies chopping away at the cos lettuce, cabbage and broccoli.

Is there a net of some kind that I can put over the vegi patch to keep
these butterflies out or is there any other method to keep them away
please.


These are cabbage moths, their grubs are very hungry and proliferate except
in very cold weather.

You can use nets to keep them out. You can use insecticide to kill them but
it will kill useful bugs and small creatures too.

You can use BT (Dipel) to kill them and it will not kill the other bugs.
