Phyllotreta chotanica was originally detected in Kununurra in 2014, however subsequent surveys only occasionally detected the pest again on three properties in the area. P. chotanica has not been detected in surveys of other regions. While its distribution is limited, it has been determined to be not technically feasible to eradicate P. chotanica from Kununurra because detections have occurred over multiple sites over a timeframe that involved many generations of the insects (short life cycle with up to 10 generations per year) and potential wild hosts are present in the area.
