Hi,
You didn't get the equivalent.
The closest equivalent to Provent-a-Mite would have been callingtons I think - or was it Ardap. Yep it seems to be ardap that has the same lingering effect.
You can get Callingtons here.
Ardap here.
And provent-a-mite here.
I'd advise buying one of them as mite off doesn't work the same way and you will have mites again as soon as the eggs hatch.
