Other Impacts of Fire Ants

Imported fire ants build unsightly mounds that interfere with farm operations.


Many aspects of imported fire ants can be beneficial, but they can cause many problems.

Impact of Fire Ants on Wildlife

In areas where fire ant populations are very high,

  • Ants may reduce populations of other ground-dwelling insects, including native ant species, with which they compete.
  • Impact on wildlife may be direct through predation (see What do fire ants eat?) or indirect by ants preying on food, such as insects on which other animals depend. Direct predation has been documented to reduce nesting success of songbirds (see Campomizzi et al. 2009). They also may attack the nestlings of ground-nesting birds and perhaps other wildlife, although impacts on wildlife populations are poorly documented. Fire ants have even been known to climb trees and enter bird nests (Drees 1994).(video). The second, indirect way fire ants impact wildlife has been demonstrated to be the case with the endangered Attwater's prairie chicken (see Message from the President and article, page 3, in The Boomer, Vol. 2, Issue 1 or see the complete report).

Impact of Fire Ants on Agriculture

  • In agriculture, their tall, hardened mounds can interfere with field working machinery.
  • Although fire ants eat certain insects, they protect and encourage population growth among sucking insects such as aphids, scales, mealybugs, and others that produce the sugary liquid called honeydew.
    • The ants feed on the honeydew rather than eat the insects that produce it. Thus, they can increase the need for insecticide use for these pests in certain crops such as cotton and ornamental crop nurseries.
