Using Thiomyl (Cleary's Generic) Indoors

[ViolinFin]

Ive read the label multiple times and the closest I can get to indoor application is "well ventilated area". Otherwise, it says to use outdoor, which probably isnt great because my only outdoor access is a balcony on the 12th floor of an apartment, so drainage would pose issues to everyone beneath me.

Of course, it was never designed to be for indoor use, but does anyone here have experience in using Thiomyl on their indoor collection?
If so, how did you go about it and take precautions?
