Fiprinil

The study evaluated the efficacy of four gel bait products containing fipronil, clothianidin, or indoxacarb against four strains of German cockroaches. While all cockroaches consumed the baits, those containing clothianidin and indoxacarb were consumed at higher rates. All baits achieved 100% mortality within 40 hours, with 0.05% fipronil and clothianidin reaching 95% mortality the fastest at 28 hours. Overall, the gel baits were found to be more effective than spray formulations against German cockroaches.

The present study evaluated the efficacy of Maxforce gel baits containing 0.

01%
fipronil (Maxforce), 0.05% fipronil (Maxforce Magnum), 1.0% clothianidin (Maxforce
Impact), and 0.6% indoxacarb (Avion gel bait; all from Bayer Environmental Science,
Clayton, CA, USA) against reference and wild strains (Mobasher, Andisheh, Tamin-e
Ejtemaei, and Maskoni) of German cockroach collected in 2016. Test design and bait
placement were according to World Health Organization (WHO) procedures for efficacy
achieving a 95% mortality rate. Although cockroaches fed on all gel baits, gel
baits containing clothianidin and indoxacarb were eaten at higher rates than gel
baits containing 0.01% and 0.05% fipronil. The cumulative mortality rates reached
100% for all cockroach strains at 32, 28, 28 and 40 h after eating baits containing
0.01% fipronil, 0.05% fipronil, clothianidin, and indoxacarb, respectively.
Efficacy (a 95% mortality rate) after exposure (consumption) of gel baits
containing 0.05% fipronil and clothianidin was seen after 28 h, compared with 32 h
for 0.01% fipronil and 40 h for indoxacarb. In conclusion, commercial gel baits
have improved and may be more effective than spray formulations against German
cockroaches.
