Argentine ants deposit trails of food continuously, instead of just from nest to food source. This habit ensures they do not waste time revisiting the same area for food. Argentine ants prefer to eat sweets, but they will eat almost anything including meats, eggs, oils and fats.
Argentine ant colonies are located in wet environments near a food source. Outdoors, they usually build shallow nests under boards or stones, beneath plants or alongside sidewalks. Argentine ants may seek shelter indoors when it becomes too wet or too dry outside.
Argentine ants do not pose a health threat, but they can contaminate food.
Pests, such as Argentine ants are attracted to moisture. To prevent Argentine ants, eliminate standing water around the property. Keep tree branches and other plants cut back from the house. Sometimes pests like Argentine ants use these branches to get into your home. Make sure that there are no cracks or little openings around the bottom of your house. Ensure firewood and building materials are not stored next to your home because Argentine ants like to build nests in stacks of wood.
