Fire Ants in Southwest Florida: Why July Is Peak Season

Summer in Southwest Florida brings sunshine, afternoon rainstorms – and plenty of fire ant activity. By July, warm soil, high humidity, and frequent rainfall create ideal conditions for fire ants to forage, expand their colonies, and build mounds throughout your lawn and gardens.

Fire ants remain active throughout much of the year in Florida, but their activity reaches its highest levels around late June and July. That makes July an important time for homeowners and property managers to inspect their yards and address colonies before they continue spreading.

Why Are Fire Ants So Active in July?

Fire ants thrive in warm environments, making Southwest Florida an ideal place for colonies to grow. During July, several seasonal conditions can contribute to increased activity:

• Warm soil encourages ants to forage and move throughout the property.
• Summer rain softens the ground, making it easier for colonies to construct and relocate their nests.
• Rapid lawn and landscape growth provides additional shelter and access to food.
• Heavy rain can disturb underground colonies and cause fire ants to build new mounds in nearby areas.

After a summer storm, homeowners may notice fresh mounds appearing almost overnight. These mounds are commonly found in open, sunny areas but may also develop along sidewalks, driveways, landscaping borders, playgrounds, utility boxes, and irrigation equipment.

How to Identify a Fire Ant Mound

Fire ant mounds often look like loose piles of disturbed soil. Unlike many other ant nests, they usually do not have an obvious entrance hole in the center. The ants enter and exit through underground tunnels located around the mound.

A fire ant colony may extend much farther underground than the visible mound suggests. This is one reason simply flattening the mound, spraying the ants you see, or disturbing the soil is unlikely to eliminate the entire colony.

Fire ants are highly defensive. When their nest is disturbed, multiple ants may quickly swarm onto a person or animal and sting repeatedly.

Important: Do not kick, step on, or poke a suspected fire ant mound to see whether it is active.

Are Fire Ants Dangerous?

Fire ant stings are painful and can leave behind itchy, raised bumps or small pustules. A single disturbed colony can produce numerous stings within seconds.

Fire ants may also build nests near electrical equipment, irrigation systems, air-conditioning units, and other areas where their activity can become more than just a lawn nuisance.

Seeing fire ant mounds? Keep children and pets away from the area until the colony can be properly treated.

Why Do Fire Ant Mounds Keep Coming Back?

Treating only the visible mound may kill some of the worker ants without eliminating the queen or the rest of the colony. When a treatment is incomplete, the colony may survive, relocate, or divide into additional nesting areas.

New fire ant colonies can also move onto a property from neighboring lawns, vacant lots, common areas, or untreated landscaping. For long-term control, it is important to look beyond a single visible mound and evaluate the surrounding property for additional activity.

Professional fire ant control can help address existing colonies while creating a more comprehensive plan for reducing future activity.

Can You Treat Fire Ants Yourself?

Store-bought mound treatments may provide temporary relief in limited areas, but proper application is important. Applying too much product, treating during unsuitable weather, or disturbing the mound before treatment can reduce effectiveness.

Some DIY methods found online, such as pouring boiling water, gasoline, bleach, or household chemicals onto a mound, can damage the lawn, create safety hazards, contaminate the surrounding area, and still fail to eliminate the entire colony.

Because multiple colonies may be present across a property, a professional inspection and targeted treatment are often the safest and most effective approach.
