I have heard that some people use this chemical to control the small hive beetle.  I found this information on the web and wondered if anyone had further information.
Fipronil

Use sparingly and avoid if pregnant or around young children
Fipronil is considered a possible human carcinogen.22 It also blocks a neural pathway responsible for preventing excessive stimulation resulting in over-excitation of the nervous system in both insects and humans.23 Fipronil binds less readily with mammalian nervous receptors than insect receptors, reducing its toxic effect in humans.24 Signs of poisoning from fipronil may include sweating, nausea, vomiting, headache, abdominal pain, dizziness, agitation, weakness, and tonic clonic seizures.25 When exposed to sunlight, fipronil breaks down into a compound nine to ten times as potent as fipronil itself.26 Studies have shown that fipronil residues from pet fur can get transferred onto a wipe or a child's hand.27 Fipronil is also suspected to disrupt the endocrine system.28
Fipronil is listed as a least-toxic chemical control by the Integrated Pest Management Practitioner.45 It is listed on EcoWise Certified IPM Program Materials List. 47 

There are significant health concerns associated with fipronil but in areas with severe tick problems limited and careful use may be warranted.
