1 oz Peppermint Oil
1 oz Rosemary Oil
2 oz Neem Oil
...
i have fought the borg in flower, and killed them all

what do commercial greenhouses do? they get these little fuckers regular
food grade horticultural oil, cheap and available
coats them and they suffocate, they can not become immune to not breathing
