Coastal Brown Ants (Pheidole megacephala), also known as big-headed ants is a very successful invasive species and is considered a danger to native ants in Australia and other places. The coastal brown ant does not sting or cause any structural damage, and usually does not bite unless the nest is disturbed, and even then, the bite is not painful. This ant is sometimes confused with subterranean termites because it may create debris-covered foraging tubes that are somewhat similar, albeit much more fragile, than termite tubes. More often these ants leave piles of loose sandy soil. Homeowners are often annoyed by these ‘dirt piles’ and by ants foraging in bathrooms, kitchens, around doors, and windows, as well as on exterior paved or brick walkways or driveways. Their attraction to food also causes annoyance within populated areas.
