I do believe that Mr Corbett missed this bit out of his report on the
toxicity of fipronil.
 
Fipronil is a highly effective, broad spectrum insecticide with potential
value for control of a wide range of crop, public hygiene, amenity and
veterinary pests.  It can generally be applied at low to very low dose
rates to achieve effective pest control.
 
The url is: http://www.pan-uk.org/pestnews/actives/fipronil.htm for
anyone who is interested enough to read the report.
 
BTW could I clear up one point I did not say Frontline drops - but two
drops of Frontline and I have clarified that is was the spray and not
the Spot-on.
