Pesticide Rotation for Carnivorous Plants: Avoid Resistance

Grower uses Bayer systemic (imidacloprid) ~5×/year; asked about "Take Down" (pyrethrins + canola oil) and other options.

Clarification

Plants don't build resistance—pests do, with frequent use.

Pyrethrins (with piperonyl butoxide) good; avoid canola oil (harms sundews/butterworts).
Neem products work fairly well.
Rotate modes of action.
