What are ants' worst enemy?

Ants' worst enemies include a combination of natural predators, environmental factors, and human pest control methods that target their colonies, with their biggest natural enemy often considered to be other ants and anteaters. Among natural predators, anteaters, aardvarks, and pangolins are famous for eating thousands of ants daily, using long sticky tongues to raid nests, while many bird species, lizards, spiders, and beetles also prey on ants. However, the most intense enemies are other ant colonies, as different ant species including army ants, fire ants, and Argentine ants regularly raid neighboring colonies, kill workers, and steal larvae and pupae, with territorial battles often resulting in thousands of deaths. Within insect world, phorid flies are specialized parasitoids that lay eggs inside ants, with larvae consuming the ant from inside, and are used as biological control for fire ants. Fungi like Ophiocordyceps, known as zombie-ant fungus, infect ants and manipulate behavior before killing them. Nematodes and parasitic wasps also attack ants. For human homes, ants' worst enemies are integrated pest management tactics, including sanitation that removes food, sealing entry points with caulk that blocks access, and slow-acting gel baits containing fipronil or borax such as Terro that workers carry back to kill the queen and entire colony within days, which is more effective than repellent sprays that cause budding. Moisture control and removing damp wood also destroy carpenter ant nests. So while anteaters and rival ant colonies are worst natural enemies, professional baits and prevention are worst enemies in houses.
