I am running into a new outdoor pest issue this year that i haven't ran into before. Each day i visit the plants outside and there is more missing,a leaf stem chewed and hanging here,leaves and new growth chewed there.In only a matter of a week or so,two plants are almost completely devoid of foliage.Whatever it is leaves behind little brown spots on leaves that look like fine dirt and it just chews leaf stems,sometimes barely touching leaves.Whatever it is really likes the new growth as most things do.I kind of thought grasshoppers,but there are none around.Then slugs came to mind,but there are no slug trails.Whatever is doing the carnage is coming at night or is so small it isn't easily visible,i have even brought chewed leaves inside and looked under magnification. I originally started spraying a mix of tobasco sauce and water,which usually will help with some pests,but had no effect,then i switched to Neem spray,which did not seem to have any effect either.It still could be slugs at night and the dew in morning washes away any trace of trail,but idk,usually still find them under leaves in morning. Does anyone have any idea what this could be and how to remedy situation before it spreads to other plants? It has already been gnawing on the other two,but damage is nothing like first two.
