inch worm?

Hi Folks, this is my first post. I've been lurking RIU for a while, and thanks to the information found here, my first grow (indoor) was successful. After harvest I started another indoor grow, and decided to add an outdoor grow. Everything's been peachy, until I found an inchworm? slowly devouring a fan leaf. Looking further, I found more on the entire outdoor crop. I've made inchworm eradication part of my morning regimen but it's slow going, and it seems I'll never get rid of 'em by this method. I'm approximately 2-3 weeks away from harvest, and certainly don't want further damage. Anyone have any other method to terminate these pests this late in the game? I'll try and post a pic (worm is circled in red at bottom) and am anxiously awaiting any comments/suggestions.

Look into BT spray..its a bacteria that kills em and harmless to you

I'll 2nd that. BT is one of the few things I found that actually works as claimed. Those inch worms are the larva of moths. Around my area there is a moth that is found around oak trees, and the little cattapilers are their offspring. I had them on my plants and after 3 good dowsings with BT I see no more evidence of them. I sprayed about every 3 or 4 days then it was as a preventative once a month or so. Safe for use anywhere, anytime.

Thanks for the info.. I did a bit or research on BT and find "Safer Caterpiller Killer" contains BT. I've seen it on the shelves at the local hydro shop, and will pick some up first thing in the morning. As I am in the 6th week of flower, I'm a bit concerned about spraying at this late date, and am apprehensive about affecting the taste of the final product. Anybody used BT this late into flowering? If so, did it in fact unfavorably affect the finished product? I'll spray in any case, but would like to know what to expect.

I haven't noticed any bad effects on late spraying. I use it right up until harvest time. Helps keep the catapillars away from the buds. Nothing worse than trimming a bud and finding catipiller poop in them.
