Pharaoh ants, scientifically known as Monomorium pharaonis, are tiny invaders that can quickly infest homes, hospitals, and commercial spaces. These ants are are notorious for their ability to thrive in various environments and their resistance to many common ant control methods.

This is why we’ve put together a guide on How Get Rid of Pharaoh Ants specifically, because the traditional methods used to get rid of ants are often slow and ineffective against Pharaoh ants. In this guide we’ll look at the specific habits of pharaoh ants, how they differ from other ant species, why they are challenging to eliminate, and, most importantly, how to effectively get rid of Pharaoh Ants.

Where Do Pharaoh Ants Like to Live?

Pharaoh ants are highly adaptable and can establish colonies in diverse locations. They often seek out warm, humid environments, making them a common nuisance in areas like kitchens, bathrooms, and heating systems. Unlike many other ant species, pharaoh ants don’t build traditional outdoor nests. Instead, they prefer nesting indoors, typically in concealed spaces such as wall voids, under appliances, or within electrical outlets.

How Pharaoh Ants Operate and Differ from Other Ants:

1. Small Size: Pharaoh ants are among the tiniest ant species, measuring around 1/16 inch (1.5 mm). This small size allows them to access and nest in extremely narrow crevices.
2. Multiple Queens: Pharaoh ant colonies often contain numerous queens, which contributes to their rapid reproduction. Unlike other ant species with a single queen, this trait makes eradicating pharaoh ant colonies more challenging.
3. Budding: Pharaoh ant colonies frequently undergo a process called “budding,” where a portion of the colony, including queens and workers, splits off to form a new colony nearby. This further complicates control efforts.
4. Preference for Sugary Foods: Pharaoh ants have a sweet tooth, and their diet primarily consists of sugary substances, making kitchens and pantries their prime foraging areas.

How Pharaoh Ants Respond Differently:

Pharaoh ants are sensitive to disturbances and changes in their environment. Traditional ant control methods, such as spraying or baiting, can cause them to scatter and establish multiple satellite colonies. Moreover, they have developed resistance to many common ant pesticides.

1. Proper Identification:

• Before attempting any control methods, ensure that you are indeed dealing with pharaoh ants. Correctly identifying the ant species is essential for successful elimination.

2. Locate Nesting Sites:

• Pharaoh ants often have multiple nesting sites, so locating all of them is critical. To find nests, closely observe ant trails and inspect areas with high activity.
• Look for pharaoh ant nests in warm and humid places, like behind baseboards, in wall voids, under appliances (especially refrigerators), inside electrical outlets, or near plumbing.

3. Use Ant Bait:

• Pharaoh ants are best controlled using ant bait stations. Select a high-quality, slow-acting ant bait containing boric acid or hydramethylnon. For more detailed steps, see our article on How to Kill Ants with Boric Acid
• Place bait stations near ant trails and potential nesting sites. Ensure the bait is easily accessible to foraging ants but kept out of reach of children and pets.
• Pharaoh ants feed on liquids more readily than solids, so opt for liquid or gel baits.

For Pharoah Ants, use a quality Liquid Ant Bait that contains Borax, like the Terro Liquid Ant Killer

4. Rotate Baits:

• Pharaoh ants can quickly develop resistance to specific baits. To prevent this, periodically switch to different ant baits with varying active ingredients to maintain their effectiveness.

5. Monitor and Replenish Bait:

• Check bait stations regularly to ensure a continuous supply. Refill or replace empty stations as needed.
• Be patient; it may take several weeks to notice a significant reduction in ant activity.

6. Maintain Sanitation:

• Eliminate food sources that attract pharaoh ants. Store food in airtight containers and promptly clean up crumbs, spills, and any food residues.
• Maintain cleanliness in kitchens and dining areas, as these are common foraging zones.

7. Seal Entry Points:

• Thoroughly inspect your home for cracks, gaps, and crevices that serve as entry points for ants. Seal these entryways using caulk or weatherstripping.
• Pay close attention to utility pipes, cables, and wires entering your home, as ants can use these as highways.

8. Limit Moisture:

• Reduce moisture levels in areas where pharaoh ants are active. Fix any plumbing leaks and use dehumidifiers to reduce humidity, especially in basements and bathrooms.

9. Declutter:

• Remove clutter from areas where pharaoh ants are likely to nest. Clutter provides hiding places and makes it difficult to locate and treat nests.

10. Consult a Pest Professional: – Persistent pharaoh ant infestations may require the expertise of a licensed pest control professional. Professionals have access to specialized baits and techniques designed to address challenging ant infestations.

11. Be Cautious with Pesticides: – If you decide to use insecticides, exercise caution. Pesticides can cause pharaoh ants to split and form new colonies, making the problem worse. – Always follow the label instructions when using pesticides and consider consulting a professional.

12. Ongoing Monitoring: – After successful control, continue to monitor your home for any resurgence of ant activity. Regular inspections can help detect and address new infestations promptly.

Remember that pharaoh ant control requires patience and persistence. These ants can be challenging to eliminate due to their unique habits and resistance to common ant control methods. Consistency in baiting and maintaining a clean environment are key to successful pharaoh ant eradication.

Pharaoh ants pose a unique challenge for homeowners and businesses alike. Understanding their nesting habits, reproductive capabilities, and resistance to traditional ant control methods is crucial when dealing with an infestation. By following the recommended strategies and seeking professional assistance when needed, you can effectively get rid of pharaoh ants and maintain a pest-free environment.
