Temprid SC got a bed bug label (PDF), see the Bayer press release at PCT.
One wishes to say, godspeed Temprid, but alas not in New York. (I have no idea why. But it’s tempting to think that DEC has its hands full ensuring we all get to use foggers for bed bugs instead.)
I guess we’ll hear whether it makes a difference. In those 48 states. The active ingredients are a neonicotinoid (imidacloprid) and a synthetic pyrethroid (beta-cyfluthrin).
In a trial with bed bug populations in poultry facilities (Steelman et al., 2008), imidacloprid fared about as well as pyrethroids. However, pyrethroids fared well with the tested populations, which I guess highlights the need to test insecticides on the actual strains that are meant to be controlled.
See also this brief note at Bed Bug Central about what sounds like an ongoing field trial.

(Heteroptera: Cimicidae) Collected in Poultry Production Facilities to Selected Insecticides Journal of Agricultural and Urban Entomology 25 (1), 41-51 doi: 10.3954/1523-5475-25.1.41
I’ll leave you with this from these authors:
As evidenced by the relative susceptibility of bed bugs to pyrethroids in this study, it would be imprudent to suggest that pyrethroids are ineffective in field applications for remedial or preventive control of bed bugs. Rather, each individual control scenario will likely dictate the choice of insecticide, the manner of application, and the level of control afforded by multiple integrated tactics employed by a pest management professional. Careful rotation of insecticides, as has been a relatively common practice for any applicator attempting to sustain the use of an insecticide, and thorough and comprehensive applications will likely control bed bugs in most urban scenarios.
That strikes me as a lot of ifs, but one can always hope.
