Thanks Steve,
I'm following the manufacturers instructions.
http://www.apithor.com.au/how_to_use_apithor.htmlHave you used them?
Manufacturer advises no residue if used as instructed.
Bloody beetles are giving me the gripes! They aren't sliming me but they are there in large numbers.
I think part of the problem is that I have had two triple 8 frame full depth hives & I have had a peek inside during winter & have noted lots of bees & honey in the third super however I didn't realise that they had left the bottom brood box leaving room for the beetles.
Single super hives in good condition don't have as many.
We have warm weather here & the bees & beetles go all year round. It is the end of winter here & there is plenty of brood but no drones.
All my hives are level & sloping slightly to the front so drainage shouldn't be a problem.
I'll get the hang of SHB eventually.
Yanta
