whatever’s bugging you.
You don’t need a corn field to have cornfield ants.
Cornfield Ants (Lasius americanus) are one of the most abundant ants in the Midwest and can be found throughout the northern hemisphere. Cornfield ants don’t reside exclusively in corn fields. They get their name from caring for the destructive corn root aphid and transferring it from grasses to growing corn. Cornfield ants are frequently found nesting in lawns, and build visible, crater-like nests.
Cornfield ants may enter homes in search of food, but they very rarely nest in homes or other structures.
Cornfield ant colonies are incredibly resilient, energetic, aggressive, and will quickly take over its surrounding area, destroying any other ant colonies that happen to be inside its territory.
Their resilience and energetic activity make cornfield ants popular with ant keepers, also because they are easy to maintain and reproduce quickly.
