Abstract: In this investigation, detection dogs are trained and used in identifying red imported
�re ants, Solenopsis invicta Buren, and their nests. The methodology could assist in reducing the
frequency and scope of chemical treatments for red imported �re ant management and thus reduce
labor costs and chemical use as well as improve control and quarantine ef�ciency. Three dogs
previously trained for customs quarantine were retrained to detect the scents of red imported �re ants.
After passing tests involving different numbers of live red imported �re ants and three other ant
species�Crematogaster rogenhoferi Mayr, Paratrechina longicornis Latreille, and Pheidole megacephala
F.�placed in containers, a joint �eld survey for red imported �re ant nests by detection dogs and bait
traps was conducted to demonstrate their use as a supplement to conventional detection methods. The
most signi�cant �ndings in this report are 1) with 10 or more red imported �re ants in scent containers,
the dogs had 98% chance in tracing the red imported �re ant. Upon the introduction of other ant
species, the dogs still achieved on average, a 93% correct red imported �re ant indication rate.
Moreover, the dogs demonstrated great competence in pinpointing emerging and smaller red imported
�re ant nests in red imported �re ant-infested areas that had been previously con�rmed by bait
trap stations. 2) Along with the bait trap method, we also discovered that 90% of red imported �re
ants foraged within a distance of 14 m away from their nests. The results prove detection dogs to be
most effective for red imported �re ant control in areas that have been previously treated with
pesticides and therefore containing a low density of remaining red imported �re ant nests. Furthermore,
as a complement to other red imported �re ant monitoring methods, this strategy will significantly
increase the ef�cacy of red imported �re ant control in cases of individual mount treatment.
