The little yellow ant (Plagiolepis alluaudi), or small yellow ant, may be tiny, but it has become a big problem in Florida. Originally from Africa and Madagascar, these pests are now found throughout the state, thanks to the region’s warm, humid climate. First recorded in Fort Lauderdale in 2017, the little yellow ant has shown a remarkable ability to spread, build large colonies, and infest homes and businesses.
Identification
Little yellow ants may be small, but once a colony takes hold, it can be surprisingly difficult to eliminate. Watch out for worker ants with rounded heads in your kitchen, pantry, or around your yard. These early signs may point to a much larger problem. At the first sign of activity, act quickly to prevent a full-scale infestation.
Habitat
Dead branches, on trees or scattered on the ground, are a common little yellow ant habitat. These ants nest in vegetation and are active foragers, feeding on flower nectar, dead insects, and tending aphids for honeydew. When food sources are limited outside, they move indoors. Small gaps around doors, windows, and utility lines provide easy access, and areas like kitchens and pantries become key targets due to the presence of sugary items and pet food.
Little Yellow Ants in Florida
Since first discovered in Florida, little yellow ants have spread quickly. They have populated suburban yards, parks, and commercial areas. This is owing to the supercolonies they establish that have multiple queens, which helps them expand rapidly and forage efficiently. Little yellow ants are competitive and often push out other ant species as the colony grows.
Little Yellow Ant Behaviors, Threats, or Dangers
There is no direct physical danger to humans or pets, but little yellow ants can disrupt ecosystems and become a nuisance. They have been known to displace other dominant ant species, like the bigheaded ant, from entire neighborhoods in under six months.
Their stealthy behavior and fast-growing populations mean they can establish a stronghold before you even notice. Once a colony takes root, it can cover several properties and be tough to eliminate. If you suspect an issue, early detection is essential.
Are Little Yellow Ants Hard to Get Rid of?
Due to their size and nesting behavior, little yellow ant infestations can be tricky to treat. Over-the-counter products may not work, particularly if a colony has spread across a yard or building. Ant exterminators use targeted little yellow ant treatment to eliminate infestations and prevent them from returning.
How Many Little Yellow Ants Count as an Infestation?
Even a few ants can signal a bigger problem. Trails along baseboards, counters, or outdoor paths may indicate a large infestation is nearby. Because little yellow ants often form interconnected colonies, what seems like a minor issue might be part of a widespread network. If left untreated, these ants can quickly multiply and spread to other areas.
