Saw a slight drop in FG/RA numbers for 1 day. The package says to keep soil moist, so I did. And the FG/RA LOVED it.
Saw an increase in numbers by the end of week 1.
I used more nematodes than recommended, which should have fixed the issue 100%, but saw no improvements.
Pretty sure they arrived dead.
I bought OG Biowar Foliar from its manufacturer.
Applied OG Biowar Foliar at double strength both foliar and in soil.
Down to just a couple fliers after less than a week. I can even see where the bacteria and microbes innoculates and killed RA....There's little fluffy balls on my soil that were once FG/RA.
I have had gnats in my home since a plant got infested and they spread to all my other houseplants. It's been awful - and none of the solutions I found online worked. There are pluses and minuses with this product, but overall, it is great.
Pluses: As I said, (so far) it works. I've used the solution twice, one week in between, and even after the first dousing, I saw a decrease in gnats the next day. I am also using the Yellow Sticky Traps, since that gets the adults while this product gets the larvae.
Minuses: The box did not have the directions inside and the directions on the box were inadequate and unclear. I had to log in to Amazon and try to read the tiny print of the instructions in the ad. Even though the directions didn't clearly state this, I ultimately emptied the entire bag into the water (the instructions seem to be saying to leave the ingredients in the inner bag - bad idea as the nematodes will not get distributed throughout the water, making the solution almost useless).
I think that those who had poor results didn't empty the bag into the pitcher of water - some even put the bag in the soil, some put the whole bag in the water, probably because the instructions are lousy - because I have been amazed at how quickly those stupid little buggers have disappeared.
Refrigeration is not necessary, which is an added plus, but it does say to use the solution quickly.
Some time later: All the gnats are GONE and were gone within a few weeks. This product is AWESOME if you can find the correct directions and then follow them. (see above)
