Why are fire ants so common here?
The state is inside the federal fire ant quarantine zone, and the insect is easily carried in soil, sod and nursery stock. New landscaping in fast-growing areas is one of the main routes in.
Clemson's Department of Plant Industry states that South Carolina is entirely within the federal fire ant quarantine zone, and that soil, hay, nursery stock, sod and soil-moving equipment are regulated articles. The federal quarantine dates to 1958, and the whole state was designated as quarantined in 2008. The practical result is that fire ants are a standing part of the landscape here, and new yards and new turf give them a fresh place to start.
What makes the cost of fire ant control go up or down?
The number of mounds, the size of the lawn and beds, and whether the colony extends under turf and landscaping all change the work. The price is explained and approved before work starts.
A lawn with a few mounds in one corner is a smaller job than a yard with mounds spread across turf, beds and the edges of a driveway. The size of the property, the number of structures and the type of landscaping all change the scope. Access matters too, since a mound in a planted bed or under a shrub takes more care than one in open grass. The price is explained and approved before any work starts, after the technician has walked the yard.
Can I dig out or flood a fire ant mound myself?
Digging or flooding a mound often spreads the colony rather than ending it. Mounds disturbed by hand can produce a quick, aggressive response.
A mound that is dug into or flooded can scatter the colony, and the workers that come out are defensive and can sting. Disturbing a mound also makes it harder for the technician to see how far the colony extends. The safer path is to mark the mounds, keep children and pets away from them, and describe where they are when you call, so the work can be planned without the mounds being disturbed first.
What should I check before new sod or landscaping goes in?
Ask where the sod, soil and plants came from, and look for mounds in the ground before they are laid. A mound found early is much easier to deal with than one found after the turf is down.
Fire ants travel in material that moves out of the zone, so the paperwork and source of new sod, soil and nursery stock matter. Walk the ground before the sod goes down and look for mounds or loose soil. A technician can explain what the regulated material means for your yard, and the regulatory requirements for moving that material are the responsibility of the people who move it. This page does not cover quarantine compliance.
How do I know the mounds are gone?
Mounds that stop appearing over several weeks are the sign that the treatment is working. A follow-up visit confirms that the activity has stopped and that no new colonies have started.
A mound can take time to respond, and a colony in the surrounding ground may still be active. The follow-up looks at the areas where mounds were found, the edges of the lawn and any new landscaping. If mounds reappear, the technician will look for the source, which may be new soil or an outside colony nearby. The plan will say what to watch for between visits.
