I've read extensively about No Pest Strips and Dichlorvos and I think it's pretty harmless if used responsibly. However, I agree that full disclosure is best and if you're touting your shit as organic you better disclose the dichlorvos use... I know some granola-type people who would flip shit about that!

I've heard of people using dichlorvos in a drying room, which is just careless as hell and could potentially be dangerous. However, if used only in veg or before flowers form then it's pretty harmless. It's broken down by water and sunlight and it's not taken up by plants. There are studies easily found via google that are very relative to growing MJ plants. Dichlorvos is used in food storage warehouses I believe.
