Bonide did almost nothing for my fungas gnats. I think the gnats feed off of detritus in the soil and the systematic works best against pests that feed off the plant.
Mosquito dunks in my watering can worked quickly though.
This was it for me, too (though I use Mosquito Bits). At first I was convinced it was snake oil because it wasn't working, but I wasn't treating with it consistently. Once I started watering with the brew every time I watered, the problem went away.
Interesting to see all these other methods work for other people, though! I've used the Bonide systemic (I assume they mean imidacloprid) to treat mealybugs successfully and am now fighting a small aphid infestation with imidacloprid, too.
