Using PAM with larger collection...

[Lolo76]

I'm not sure what type of rack set-up you have, but once you remove the snakes and tubs, couldn't you move the empty rack out of the room and spray it first, then it can dry while you do the tubs?

I thought of that, but with my bad back I'd have to enlist a friend's help... plus the snakes are on the second floor, with the other upstairs room about 3ft away. So they'd probably still get the fumes! I'll just treat the tubs alone, and re-evaluate in about 30 days - if any mites have returned, then I'll go through the process of PAM-ing the racks & room. Thanks for the tips!
