Bigheaded Ant Identification

Bigheaded ants (Pheidole megacephala) are a common sight in many parts of the United States and are known for their distinctive large heads. At Arete Pest Control, we understand the importance of identifying and understanding the behavior of pests like Bigheaded Ants. That’s why we’ve compiled some tips to help you identify and control them. Bigheaded Ants are small to medium-sized ants that range in color from light brown to black. As their name suggests, they are easily identifiable by their disproportionately large heads, which are often two to three times larger than the rest of their bodies. Workers of the species typically measure between 2.5-3.5mm in length.

 Bigheaded Ant Behavior

Bigheaded Ants are known for their habit of nesting in soil and mulch, often building mounds that can grow up to several feet in diameter. They feed on a variety of insects, including termites, and are often considered beneficial in controlling termite populations. However, when they invade homes and other structures, they can become a nuisance.

Bigheaded Ants are also known to farm aphids, mealybugs, and other insects for their honeydew, a sugary substance produced by these insects. This can lead to an infestation of the ants, as they tend to the insects and protect them from predators.

Bigheaded Ant Control and Prevention

If you’re dealing with an infestation of Bigheaded Ants, there are several steps you can take to control and prevent them. First, eliminate any sources of food and water that might be attracting them. This includes fixing leaky pipes, sealing up food containers, and keeping your outdoor trash cans tightly sealed.

Next, try to do the following:

Use Ant Baits and Insecticides: Look for ant baits and insecticides that are labeled for use against Bigheaded Ants. These products are formulated to attract and eliminate the ants effectively. Follow the instructions provided on the product label for safe and effective use.

Maintain Cleanliness and Hygiene: Keeping your indoor and outdoor spaces clean is crucial in preventing Bigheaded Ant infestations. Regularly clean up food crumbs, spills, and any other food sources that may attract ants. Ensure proper storage of food items in sealed containers to minimize access for ants.

Seal Entry Points: Identify and seal any cracks, gaps, or openings in your home’s foundation, walls, and windows that could serve as entry points for Bigheaded Ants. Pay attention to areas where utility pipes and cables enter your home and seal them properly.

Trim Vegetation and Remove Debris: Bigheaded Ants often build their nests in vegetation and debris around your property. Regularly trim bushes, trees, and other plants that may provide nesting sites. Remove any piles of leaves, branches, or other debris where ants might find shelter.
