| Post subject: | Gnats in Aquaponics |
I moved my AP system from a side porch to my basement so I could keep it going year round. In a matter of only a few months, I now have a boat load of growth BUT....the leaves, GB edge, top of the bell siphon, etc has a lot of tiny, little brown specs on them. I'm assuming these are from the tiny, little green gnats that are there. What is safe to use to kill/deter these gnats?? |

Any idea what type of gnats they are? Good pics might help. |

You have aphids (the green ones), probably run-of-the-mill peach aphids or similar, the white bits are their sheddings. The pics are a bit out of focus so it's hard to see what the brown dots are, but they are quite a bit smaller than the aphids, so they could be spider mite. |

How do I get rid of them..."organically"? |

Neem Oil... It's non-toxic to humans, mammals, birds etc, but kills insects on contact and can also have a repellent effect that lasts for 4 or 5 days. Thoroughly cover any exposed areas of gravel in the grow bed with newspaper 3 or 4 sheets thick, then spray the underside and upper surface of the leaves with a fine mist almost to the point of run-off. Using the Neem oil concentrate at the recommended rates usually kills any aphids on contact, but they start coming back within a couple of days. I've found that when making up the solution I need to add the concentrate to the water at twice the recommended rate for it to have a longer lasting repellent effect. Also, use slightly warm water when making up the spray solution, about 35C. |

Avoid getting the neem oil in the system water as much as possible. You might also have luck with a chili/garlic spray that's listed around here someplace. |
