Big Headed Ant

How To Control Big-Headed Ants

It’s amazing the different number of ants that can invade a home. If you come down with an ant infestation one season, the next season you may encounter a totally different species of ant with different tendencies and characteristics. One such ant which can be a problem is the big-headed ant which are often mistaken by homeowners to be termites since they are larger than the average ant.

Big-headed ants are light brown to dark reddish brown in color, and have two distinct sizes of worker ants.  One size is an ⅛ of an inch long, has an enormous head and is referred to as the major worker.  The minor workers are 1/16 of an inch and do not have large heads but can be recognized by their head shape, which narrows abruptly behind the eyes.  

Big-headed ants are more common in warmer areas of the country and are a particularly large problem in Southern states like Florida and Texas as well as Hawaii. Big-headed ants are also soil-dwelling ants and are known to nest under logs or rocks or even under the slab of a building. They often enter structures through cracks or seams in the foundation and around windows and doors. While they may not set up a nest inside homes, they do often enter homes while foraging for food and water.

If you have a problem with big-headed ants on your property, there are ways to eliminate this frustrating pest. Whether you’re looking for control products or free advice from DIY experts, Solutions Pest and Lawn has everything you need to get rid of big-headed ants.

How To Get Rid of Big-Headed Ants: Solutions 4 Step Process

Controlling ants, especially one as stubborn as the big-headed ant, can be tricky if you go in without a solid plan. The best approach is to have a multi-faceted plan if you want to achieve results in getting rid of a big-headed ant infestation. Solutions Pest & Lawn recommends a combination of baits, granules and sprays for controlling big-headed ants along performing exclusion and sanitation tasks designed to make your home less welcoming. Below are some of the steps we suggest for the greatest success in managing this pest.

Step 1: Every good ant control program starts with a detailed inspection. When it comes to big-headed ants, you need to start your inspection outdoors and then work your way indoors. Pay particularly close attention to the soil and if need be lift items in contact with the soil to check underneath for ant colonies. Examine the ants themselves to make note of their trails and runways. Indoors, big-headed ants can be found in walls and voids, and around wherever there is dampness and moisture.

Step 2: Destroy Ant mound and/or nests. Once nesting sites or ant mounds are located treat them immediately by applying an insecticide such as Reclaim IT Insecticide or FiPro Foaming Aerosol. Spray to the point of drenching the nest, the insecticide will then work to kill the entire population. Make sure to keep pets and children away until the treated area has been dried.

Step 3: Once the mound has been treated, there are likely many ants still out foraging. We recommend using granules such as Bifen LP Granules to take care of the remaining outdoor population.

Step 4: For ants that have made their way indoors, we recommend using baits over sprays. Try a slow-acting bait like Extinguish Ant Bait. To judge whether a bait is effective in eliminating the indoor ant problem, simply monitor whether the placement is being visited or decreasing in size. If not, switch to another bait until you find one that the big-headed ants will accept. Please allow at least 2 weeks for the bait to work. Do not be discouraged if ants are not picking up bait immediately. Be patient when it comes to baiting as it can be a slower process but is effective.
