Dark @entity26096 ants (Brachymyrmex patagonicus, Mayr) are an exotic ant species native to South America that has recently spread through the southern US. We evaluated the residual activity of three liquid insecticides ( @entity68769 , @entity276 and @entity4204 ) as potential barrier treatments against these ants. The factors we considered include the use of a porous or non-porous surface, a short or long exposure time and the changes in insecticide activity after treatment during a 90 day period. We also tested the effect of baits containing three different @entity3457 ( @entity5051 , @entity33504 and @entity68769 ) on colony fragments of this species for a 15 day period. Both @entity4204   and @entity68769   resulted in high levels of ant mortality up to 90 days after application. The results of exposure to @entity276   resembled those from the control treatment. Application of insecticides on a porous surface and the shorter exposure time generally resulted in greater ant survival. Of the baits tested, only the @entity5051 based one decreased ant survival significantly during the evaluation period. Within three days, the @entity5051 bait produced over 50% mortality which increased to over 95% by the end of the experiment. Results from the other two bait treatments were not significantly different from the control.
