i had them for the first time last year and im pretty sure
@thumper60 who has grown in the swamps for ever,said hes just started seeing them over the past couple seasons.i know its not feasible for a lot of growers,but i put up a damn,old school bug zapper well away from the garden, in hopes to kill the moths that lay the eggs that turn into worms.i only found a few actual worms throughout my season,i checked every am/pm like D's but its damn shocking to find them,no doubt.they stick out pretty well.one other trick is lavender,thats a natural deterrent to those moths.i planted a window box full between my plants.infeasible for guerilla grows,though.
