Likely too many plants to treat manually through removal or soaking, unless absolutely necessary. Seems like the most commonly prescribed insecticides are either Neem or Bayer (imidacloprid)? Considering this is an indoor collection, would prefer something not smelly (which I hear neem is) and also not horrible to breathe in (although will be spraying outside regardless).
My first time dealing with an outbreak of this size so appreciate any guidance. Also wondering if it's worth treating my Drosera tray on the shelf underneath even without showing any signs of aphids there yet.
