I seem to have become infested with them (well not me personally, but my veg patch). I've got a 4 month old veg patch with a few things growing nicely in thee including lettuces, capsicums, carrots and a few herbs amongst other things.
The past few days I've noticed a lot of my leaves showing signs of being eaten, and yesterday I picked 3 caterpillars of my lettuce and 1 off my basil. This mornings watering flushed 2 white butterfly's out from under the capsicums.
Does anyone have a good organic way of getting rid of these blighters and preventing them coming back?
