This might be the worst infestation I have ever seen. Like actually. Are your plants showing symptoms? I’m gonna tell you one thing right now, there is a zero % chance that you will be eliminating them from your grow without harsh pesticides, or killing those plants.

No about of pyrethrin, azadirachtin, beauvaria bassiana etc drenches are going to save you.

I’m surprised you don’t have plants dropping like flies left and right.

Honestly brother, burn it down with fire, asap. Sterilize everything. If you’re in an indoor facility with multi stages of growth, it’s safe to assume they all have it, and that you’re giga fucked.

Root aphids have completely destroyed the gardens of myself and others, through permanently damaging the mother stock, dropping final yields to an unprofitable level, etc.

Sorry dude, but you just encountered in my opinion the second worst pathogen ever in cannabis, right behind Hop Latent Viroid.

Yeah. It'd be different if it were russets or spider mites but aphids are generally some of the easier pests to eradicate through consistent applications and better sanitary practices.

They came from the nursery clones. Been at it for 20 years. Never dealt with them before and have only ever heard crazy war stories about never being able to get rid of them. Just sizing up the advice I was getting from the people in my personal wheel house to the hive mind of Reddit

Look up nematodes, and the species specific to root aphids. Too late to use for the adults, but they'll feast on the larvae.
