pest spraying and repotting

[The Griffin]

I see some pest activity on some plants that really need to be repotted anyways.
I thought about unpotting, and then spraying with the roots just wrapped with some lfs in a baggie before repotting.
Has anybody ever tried this before?

Most insecticides are recommended for use with potted plants; and bare-rooted plants may be too stressed to tolerate the often oil-based spray. I would either re-pot them, wait a few weeks, then send death from above; otherwise, spray them as they are.

Just my two cents . . .
