I followed up the link  http://tinyurl.com/b8hol supplied by Allen Dick,
relating to the discussion on non permissible treatments against SHB.

Off label, illegal use of pesticides etc. is a reckless action to undertake.
Apart from the easily understood issue of breaking the law, such action
may "bite back" and cause an unexpected situation.

Glancing at the composition of some of the "Roach baits" - as shown in
the links and web pages, the molecule - FIPRONIL is indicated as an
active ingredient in several brands.

This molecule has a history - one that beekeepers should be aware of.
Agree or disagree with what can be found after searching
"Bees + Fipronil", proprietary products containing this molecule should
IMHO be treated with caution.
The following link supplies a sensible resume about the molecule:
