Little Yellow Ant

An ant species that has been recently making headlines is the little yellow ant. While it is very small, like their name suggests, being 2 millimeters long at the most, they can cause very big problems via their rapid breeding and formations of super colonies with gigantic ant populations.

Little yellow ants first started appearing in the states, particularly in Florida, in early 2017 and by mid 2017 their residence increase ten-fold and they began dominating the area of South Florida which researchers believe to be due to the aftermath Hurricane Irma. 

Solutions Pest & Lawn has been keeping a close eye on the developments in Florida and have control measures in mind to keep this invasive ant species from spreading and doing further damage.

Little Yellow Ant Background Information

Little yellow ants Plagiolepis alluaudi are very tiny that they could be hard to detect. They are about 1/16th of an inch long. They are yellow to light brown in color and are native to Madagascar and prefers tropical areas which makes it no surprise that they have been thriving in South Florida’s climate. What makes this ant so difficult to control is that they can create supercolonies with multiple queens. 

Unlike most ants, little yellow ants prefer to nest indoors over outdoors. They are notorious for being found in establishments that handle large amounts of foods like hotels, grocery stores and hospitals. Inside, they nest in warm, humid areas wherever there is plenty of food and water nearby. Like many other ants, little yellow ants primarily like to eat sweets and sugar-based foods as well as food that is really greasy. 

Outdoors they enjoy Flower nectar and honeydew discharged by sap-sucking insects and have been of some concern to agricultural farmers with their presence. Yellow ants are attracted to insects like aphids, mealybugs, and scale insects, all of which produce honeydew, this invasive species may potentially impact agriculture by harming crops and ornamental plants. Little yellow ants will go out of their way to protect these pests in exchange for their sweet food. Fortunately, little yellow ants don’t sting or bite but their presence, especially in large numbers can be an annoying problem.

If your home or place of establishment has become infested with little yellow ants, Solutions Pest and Lawn can equip you with the best products and knowledge to eliminate the infestation yourself. Keep reading below to learn the best recommended products for little yellow ant control and the best strategy to tackle these nuisances.


An effective little yellow ant elimination program is not as simple as purchasing a product that targets ants, spraying it around and calling it a day. Little yellow ants need to be dealt with in a more sophisticated fashion because they are a clever insect. For that reason, baiting is the most effective way to get rid of little yellow ants. By following the steps we laid out below you can get rid of little yellow ants all by yourself.

Step 1: Locate the areas of high ant activity. This will require a very detailed inspection of your home. You cannot tackle the ant problem until you are aware of their hot spots. One of the best ways to do this is by carefully observing ants that are wandering and taking note of the trail they create while foraging for food. Mark these areas. If the trail isn’t made obvious, use a harmless bait like peanut butter and wait for ants to come to it and you will then notice their ant trail, which will be vital in the ant baiting process.

Step 2:
Once you have made note of the ant trails, you can then proceed with baiting the area in a strategic fashion, preferably along the ant trail you have marked. What we recommend is a sugar-based sweet bait such as Ant-Trax Ant Gel Bait. Please give the bait product 2 weeks to do its job before taking further action or reapplying. It is very important not to disrupt ant activity while bait is out. Leave them be and let them take the bait to their nesting sites to share amongst one another to create the desired domino effect.

Step 3:
You can use a insecticide spray such as Reclaim IT to create a barrier around your home to aid in keeping little yellow ants out of your home as well as apply around voids, cracks and crevices in the kitchen and bathrooms. Do not spray in areas where bait has been laid out as it will render the bait ineffective.

Step 4:
After the baits have taken care of your little yellow ant problem, you will need to take proactive measures to make sure they don’t come back. This includes implementing preventative measures such as: reducing moisture by fixing leaks, thoroughly cleaning your home (particularly the kitchen) to clear up crumbs and grease, sealing up cracks and crevices with caulk, clearing off debris and firewood from your home and trimming trees that touch your home.
