Aldrich doesn't list Tedion (A.K.A. 2,4,4',5-TetraChloroDiphenyl Sulfone) 
in its catalogue, but if you call their Rare Chemicals department, you 
can found out how much they currently have available. It is currently 
listed in the company computers, with catalogue number S42834-5 for five 
grams, and sells for $35 (their minimum price for rare chemical orders).

Good luck with it. I've tried to use it recently against an infestation 
of what appear to be Histiostoma mites (but without the hypopal stage 
that drives the flies and us crazy). The mites ignore the paper 
impregnated with the Tedion. Oh, well ...
