Habitat Preferences of Cornfield ant Through Different Life Stages
To find the diffent growth and development stages of cornfield ant, one must explore a variety of habitats. The eggs, typically located inside secure, underground nests, require searching through soil in protected environments, often under rocks or inside decaying wood. Larvae and pupae also inhabit these nests, preferring the warm, humid conditions provided by the colony's intricate architecture. Adults may venture outside the nest in search of food, commonly found scavenging on the ground in grassy or forested areas.

Are Cornfield ant harmful to humans?

Different kinds of ants cause different troubles to humans. To be sure, compared with other dangerous creatures, common ants are very harmful to humans, and most of them just gather in the courtyard or room to disturb human life.
But there are some dangerous groups. They have strong jaws and sting needles and can bite or sting when under stress. Usually, ants only cause physical damage and the pain caused by formic acid. These discomforts do not even need to be dealt with, and can be recovered quickly. But there are still very few ant stings that can cause allergies and even death. Other ants can pollute the environment, destroy buildings, affect harvests and even spread diseases.
