Any idea if Neem oil is ok to use in a system that contains fish? (Aquaponics). I've gotten a recent and rather massive mess of aphids and fire ants living in my grow beds.
I wouldn't use it with fish... Itvis mildly toxic to them, and I would be concerned about suffocation from the fatty acids in it; ie, the oil...
Edit* further thought.... Maybe beneficial nematodes would be a better option.... Fire ants in aquaponics; I'm not envisioning how that happened!
