I used OGbiowar to eliminate Gnats. Have never had them since. I found the biggest thing with Fungus Gnats is overwatering the soil provides a perfect living environment for them. Try to let your plants dry out properly before watering, and you should notice a significant drop in their population. Sticky traps help track how many are around, and hit them hard with tea as soon as you see some coming back.I have question about the OGBiowar. What strain of BT is in it?
This is why Im asking. When the weather was hot, I was getting fungus gnats in my room. I bought Moquito Dunks from Walmart (BT)and ground them up soaked them in water for 24hrs and drenched my plants. The gnats thrived in it and it did not effect them.
Then I bought the OGbiowar and brewed up a tea. I overdosed my plants with it and drenched the soil. The same thing happened, the gnats just played in it and I found larvae in my medium. I did this for months with no improvement.
Then I bought Gnatrol off ebay, which is the same thing, BT. It murdered every single larve in my medium.
Why dont the Walmart Mosquito dunks or the Ogbiowar do anything for fungus gnats but the Gnatrol does? Are you using the wrong strain of BT or is it the concentration?
I found the same thing happens with Spinosad, I believe the concentration made the difference because Montery and Captain Jack's didnt work for me either.
