The visible activity may stop for a while. Some workers may die. The mound may even move. None of those results proves that the queen and colony are gone.
Fire ants live in a deep, organized nest with thousands of workers and one or more queens. A remedy that reaches a few ants near the surface can create an impressive scene without providing reliable control. That difference explains why the same mound often seems to return after someone thought they had eliminated it.
Around Bryan, College Station, and Brazos County, rain makes old colonies visible and helps new colonies develop. Home remedies do not change the larger population surrounding a property.
The Mound Is Only the Front Door
The pile of loose soil above ground represents a small part of the nest. Tunnels extend below and away from the mound. Workers move the queen and developing ants as temperature, moisture, flooding, and disturbance change conditions.
That mobility creates a common illusion. Pouring a material into one part of the mound may drive activity deeper or shift it to another opening. The original soil pile goes quiet, so the treatment appears successful. Days or weeks later, workers rebuild nearby.
Visible dead workers also tell only part of the story. Workers support the colony, but lasting control depends on reaching its reproductive center. A method that kills exposed ants while leaving queens and brood protected cannot deliver dependable colony control.
Club Soda Produces Bubbles, Not Control
One popular claim says carbon dioxide from club soda displaces oxygen inside the mound and suffocates the entire colony. The theory sounds scientific, but field testing did not support it.
Texas A&M AgriLife Extension reported on controlled trials conducted by entomologist Wizzie Brown. Her observations found no evidence that club soda controlled the colonies. The liquid produced obvious bubbling and may have drowned a few ants, but the colony survived.
Soil contains countless connected pores and passages. Gas and liquid do not remain perfectly sealed around every ant, and the queen may sit far from the point where someone pours the soda.
Rice and Grits Do Not Make Ants Explode
Another story claims that ants eat dry rice or instant grits, drink water, and burst when the food expands. That is not how adult fire ants eat.
Adult ants take in liquids through narrow mouthparts. Workers can carry solid food to the colony, but they do not swallow a grain into a stomach that later explodes. Larvae help process solid foods for the colony.
The Texas A&M fire-ant FAQ specifically addresses the instant-grits version of this myth and explains why it fails. Substituting rice does not repair the biological problem with the claim.
Rice and grits may disappear from the mound because workers move them. Movement does not equal poisoning, digestion, or colony death.
Soap Can Kill Contacted Workers
Soapy water can kill ants that receive enough direct contact. That makes it tempting as a mound treatment because dead workers appear quickly at the surface.
The limitation remains reach. The mixture must contact an ant to affect it, while the nest protects queens, brood, and much of the worker population below ground. Soil absorbs and redirects liquid. Workers can also move away from the disturbed area.
A quick reduction in surface activity does not prove that the colony died. It may recover, relocate, or reopen through another tunnel. Soap can also affect turf, soil organisms, and runoff depending on the formulation and amount, so “household” does not automatically mean harmless outdoors.
Gasoline and Fire Create a Real Emergency
Gasoline, diesel fuel, and other petroleum products do not belong on an ant mound. They create fire, inhalation, soil, water, plant, and property hazards. They may still fail to kill the entire colony.
Texas A&M gives an unusually direct answer about gasoline: do not use it. Their FAQ notes the danger, plant damage, soil residue, and unreliable colony control.
Lighting a mound creates an even greater risk. Fire can travel, ignite vapors, damage buried utilities, and injure the person attempting the treatment. No mound justifies turning a pest problem into a medical or fire-department problem.
Why the Colony Seems to Return
Sometimes the same colony survives below ground. In other cases, it moves and rebuilds nearby. Even successful removal of one colony leaves open habitat that another queen can occupy.
Warm rain can trigger mating flights across an entire neighborhood. Winged males and females travel well beyond the property where they developed. Mated queens land in suitable soil and begin new nests that may remain inconspicuous for weeks.
This regional pressure explains why one-mound thinking falls short. A yard can look clear today and develop new colonies later without any surviving ants from the original mound.
Our fire-ant pest library page explains mound biology, worker sizes, mating flights, stings, and the role of native ants in the landscape.
A Property Strategy Works Differently
Reliable fire-ant management treats the lawn as a changing population rather than a collection of isolated soil piles. It accounts for colonies that have not built obvious mounds, seasonal foraging, weather, property use, and reinvasion.
That approach also avoids trying to eliminate every ant. Harmless native ants occupy space, compete for food, and may prey on newly landed fire-ant queens. Correct identification helps preserve species that do not sting people or invade buildings.
Venus Pest Company’s standalone Fire Ant Control Program includes scheduled whole-yard service. HomeGard, HomeGard Plus, YardGard, and TotalGard also include lawn fire-ant management. Basic Pest Control covers fire ants around the structure perimeter but does not cover the whole lawn. Commercial properties receive coverage based on the areas listed in their proposal.
We do not publish pesticide product names, active ingredients, rates, mixing instructions, or homeowner application recommendations. Weather, timing, site use, colony behavior, and the treatment area all affect professional decisions. A short recipe would leave out the judgment that makes a program effective and responsible.
What You Can Do Safely
Teach children to recognize mounds and avoid them. Check play areas, pet spaces, gardens, mailboxes, and places where someone may kneel after rain. Keep people and animals away from a suspected colony instead of kicking or probing it for identification.
Take photographs of the mound and workers from a safe distance. Note whether the problem affects only the building perimeter or the larger lawn. That distinction helps us match the property with the correct service level.

Questions About Popular Mound Remedies
Does club soda suffocate the queen?
Texas A&M field testing found no evidence of colony control from club soda. It creates bubbles and may drown a few ants, but the nest does not function like a sealed container.
Will rice or instant grits make fire ants burst?
No. Adult ants consume liquids and cannot swallow whole grains that later expand in their stomachs. Workers may carry particles away, but that does not eliminate the colony.
Does soapy water kill fire ants?
It can kill workers that receive enough direct contact. It does not reliably reach every protected part of a deep colony, so visible worker deaths do not prove that the queen is gone.
Can gasoline eliminate a mound?
It may kill some ants but often misses the entire colony. It also creates serious fire, health, plant, soil, and water hazards. Never pour petroleum products onto a mound.
Why did the ants build another mound nearby?
The colony may have moved after disturbance, or another colony may occupy the area. The soil pile can shift even when many of the same ants survive below ground.
Why do new mounds appear after rain?
Moist soil makes excavation easier and reveals colonies that already existed. Warm rain can also support regional mating flights and the establishment of new colonies.
Does Venus treat individual mounds?
Our coverage depends on the service. Basic Pest Control covers the structure perimeter. The standalone program and qualifying Gard plans include whole-lawn management, while commercial turf coverage must appear in the proposal.
Can fire ants be permanently eradicated from a yard?
No program can prevent every future queen from flying into a property. Ongoing management can keep pressure very low within a defined area even though fire ants remain common across the region.
