d/e was the first thing i thought of when i started to ponder any possible mass destruction weapons against such pests in these past couple of days, should i have a repeat of this...or better yet to prevent it before it happens again... some years ago my mom had an insect issue [grubs, gnats, et al.] in her garden and i suggested we's try d/e along with nematodes...it worked very well but this was in the outdoor garden soil and after thinking about using it in the bags for my current grow attempts i didn't think it would work much in the same way due to a completely different manner the watering cycle works via the indoor bags grow, etc... however, since you've already tried it with positive results [and i'm guessing you did so on your indoor grow thus using bags/containers] that's great news... for preventive measures i'll definitely use it when i'll begin my next couple of plants, thanks...
yes, i just came to the same conclusion over the past 24 hours as i lied in my bed trying in vain to fall asleep last morning... not only that but i now also think that it's the overwatering in late evening - a few hours before they all came out of the bags - that actually made them flee the grow bags during the night... they probably were abandoning the bags en masse to save themselves from being drowned... my mom turned the light out in the tent and watered the bags around midnight before turning in and the next morning found the insect pandemonium inside that tent... the bags drained much more efficiently of the possible excess water while they were outdoors so overwatering didn't manage to cause them to actually drown but once inside the more humid environment of the tent the water probably didn't run nor evaporate through the bag/soil as quickly and it was suddenly general quarters for all hands on deck inside those bags... that's my tentative, newest hypothesis anyway...
