If gnats are the primary concern you can very easily get some Mosquito Dunks (or Bits). Dunks are sold at virtually every home improvement store. What is in them is Bti which is a kind of Bacillus bacterium and it produces a toxin that will kill mosquito and fungus gnat larvae (without hurting anything else). Your grow store probably has the Bits, but the dunks work as well you just have to break the dunk up some and then soak in a water for several hours. You could also mix crushed dunks or bits into the soil directly and then water. These work best before you have a problem so now would be the time.Sounds great, where can I find more info on or evan purchase Hypoaspis mites and nematodes ? thanks...J.L..
Predator mites and nematodes you should be able to get online, or through the grow shop perhaps but they may have to order them for you. The nematodes you wouldn't even be able to see without a microscope, and they are kind of expensive but they parasitize some 200 different kinds of pest insects.
I have so many mites that I'd be willing to ship them out personally to anyone (in the US) that asks and is willing to pay for the shipping. The only issue there would be thinking of a creative way to ship them so that they both survive and also cannot leave the packaging.
