A Closer Look with Heather Patterson
Red Imported Fire Ants are a non-native, mound-building ant species that has become established in many U.S. states, particularly in the southeast. Workers within the fire ant colony vary in size, and will aggressively defend their nests from threat or disturbance. As for coloration, these ants will usually have reddish to brown heads and bodies that transition to darker, almost black gasters (abdomens). Another identifying feature (if you choose to examine closely) will be the two nodes, or bumps, located on their thin waist just before the large gaster.
Are they commonly confused with other ants, and if so, what are the differentiators?
Is there a certain time of year to treat for fire ants? If so, when?
How should professionals treat for/control fire ants (ex. chemicals/modes of action to use, cultural practices, etc.)?
Are there mistakes to avoid or things not to do when treating fire ants?
Is there anything else lawn care professionals should know or do to control fire ants?
