The MOMENT you watered with the H20 solution, you killed every larva.

You have to put sticky traps down ahead of time and afterwards to round up the adults that are still in abundance flying around, before they get a change to procreate back into your sterile soil.

Yes, the solution will definitely fry the larvae, and as maxwell mentioned.. fly strips fly strips, more fly strips.

Till the soil a bit too and spray, i think they have larvae under the soil a few inches as well.

Is why I usually recommend that ratio with a soil drench as long as it's only 3%, to ensure that everything gets taken out in 1 shot so there's no lurkers

Ya, totally soak the soil.. they h202 will actually aerate and leave behind air pockets with all the bubblling.. the soil will dry out much faster this time than with just regular water...

Standard dilution for 35% food grade H2O2 is 1:11. Hope you did not FRY your leaves. Spray them ASAP and correct your dilution
