Tawny crazy ants (TCA), or Nylanderia fulva [Mayr], are one of a number of pest ant species that have been accidentally introduced to the U.S. mainland from abroad (Figure 1). The establishment and subsequent expansion of TCA have proven to be a major nuisance to property owners, disrupting ecological balance by outcompeting native ant species, negatively affecting various arthropod and vertebrate animal species, and becoming an economic pest. Examples of other invasive ants that have made their way to the U.S. since the late 1800s include the red imported fire ant (Solenopsis invicta), the Argentine ant (Linepithema humile), the bigheaded ant (Pheidole megacephala), the ghost ant (Tapinoma melanocephalum), the dark rover ant (Brachymyrmex patagonicus), and the Asian needle ant (Brachyponera chinensis), to name a few.
