Hi Lone, from what I read in the instructions, after you put a tablet in say a sealed Wheelie Bin in reacts with moisture in the air and becomes Phosphine gas at temps 25c plus it will take 7 days to totally dissolve into gas at less than 25c 10 days.
They also list a ventilation period of 1-5 days
I was just seeing if anyone else had used it. I have frozen my combs, thawed them out and now wish to store them to get some freezer space back.
So from what I have read after the oxidation process all BUGS are killed, then prior to usage you air the exposed combs for 1-5 days.
I am just a little unsure
