Not at all man. The dunks only affect the flying insects and their larvae. I got loads of nematodes. Too many maybe LoLHey Fattie wont the dunks and nematodes have a problem together?
On that note, is there such a thing as too many nematodes? It seems I have millions of them now. Not doing anything harmful that I can tell.Nematodes and BTI dunks actually work very well together and that's what I would do. And top dress in some Neem and / or Kranja meals. Crab shell meal also. You'll see adults around for a while. Then they'll die.
