Yeah - don't use neem oil or dishsoap.. TheMeditrerranean81's wife probably doesn't grow anything that you would inhale or eat immediately after spraying with that concoction although it might work on houseplants and flowers...
You say in your diary you've finished the grow - meaning you've harvested... I would do as Roberts suggests and freeze your dried buds to make sure they're not in it.... But beyond that, I would thoroughly sanitize the tent and your equipment to kill off any little mites that might be hanging around waiting for the next victim ... and then I'd make sure I had either some Dr. Zymes Eliminator or some Spinosad on hand for my next grow in case they show back up. Both products are organic and both can be used straight through to harvest if need be...
Good luck!
