Argentine Ants are a common household pest, often entering structure in search of food or water (particularly during dry or hot weather). They also enter to escape flooded nests during heavy rainfall or irrigation.
Pest control usually requires exploiting their omnivorous dietary habits through slow-acting poison bait, which will be carried back to the next by workers. This eventually kills all the individuals, including the queens. It may take four to five days to eradicate a colony in this manner.
