So now I am thinking of spraying with isopropyl alcohol mixed with a bit of detergent as suggested in this link provided earlier in the thread:

There are comments elsewhere in thread about diluting the alchohol but no definitive dilution is provided that is known to kill the bugs but not harm the fig tissue. Has anyone used this treatment successfully with figs and, if so, what dilution did you use? Thanks!
