Argentine Ants


Argentine Ants can be found in AL, AR, CA, FL, GA, IL, LA, MD, MO, MS, NC, OR, SC, TN, WA. Their colonies can grow to monumental size. Their colony borders sometimes cover entire habitats. Argentine ant queens also assist with foraging for food. The ant gives off a musty odor when crushed. Worker argentine ants are about one sixteenth of an inch long. Queen Argentine ants are one eighth of an inch to one quarter of an inch long. Argentine ants deposit trails continuously, instead of just from nest to food source. This habit ensures they do not waste time visiting the same area for food. They prefer to eat sweets but they will eat almost anything including meats, eggs, oils and fats.

Argentine Ants Habitat

Argentine ants colonies are located in wet environments near a food source.

Threat of Argentine Ants

Argentine ants do not pose a health threat, but they can contaminate and thus spoil food. They will also cause substantial distress to children, and stress for adults, when present in a residence. Residential pest control measures should be taken immediately.

Treatment for Argentine Ants

An Argentine ants infestation can really only be addressed properly by a professional pest control company. Incorrect pest control treatments can stimulate the queens to lay more eggs, which makes the problem worse. Your pest control company should use bait that gets carried back to the nest and consumed, eventually killing all ants. They should also do a full inspection, and put forward a structural change action plan to eliminate entry points.
