Hi this might help,
I found little green catterpillars 3 wks ago.
I was told to use DT which I had on hand. But a helpful person from FoXFarm
told me to try Dont Bug Me. sold online and at local indoor garden shops
after 3 consecutive sprays their gone and apear to not be coming back.
didnt need to DT them. Im keeping very close eye on them just in case eggs hatch.
you can use this product all the way to harvest day with no ill affects on the taste and quality. Hope this helps
good luck
