We (Oz) now have a commercially available trap incorporating Fipronil.  
They work very well.  I assume beekeepers are still using their home 
made ones.  There was almost no difference.

Tests have not been able to find the chemical in honey wax as far as I 
know.  The product is very stable I believe and  low vapour. However 
great care needs to be taken to ensure that they do not get wet.  They 
are designed to go on the floor, so it is important to have the hive 
sloping forward.

Before you think I am an advocate, I might point out that though they 
are very effective in regard to the beetle,  I see no actual obvious 
benefit to the production or apparent bee numbers in a hive or nuc.  
When making nucs or putting into bottom boxes these days however I do 
not use any empty comb, rather foundation.

I think the traps would be useful for mating nucs as they tend to be 
kept a little weaker than increase.

Hopelessly queenless hives are a goner of course.
