Pharaoh ants (Monomorium pharaonis) can be identified by their small size and distinctive coloration. They are light yellow to reddish-brown, with the head and thorax usually darker than the abdomen. Here are some additional characteristics that can help identify Pharaoh ants:

• Size: Pharaoh ants are very small, typically measuring about 1/16 inch in length. They are among the smallest ant species and can be difficult to see with the naked eye.
• Body shape: Pharaoh ants have a slender, slightly curved body shape, with a narrow waist and a bulbous abdomen. The thorax is rounded and does not have spines.
• Antennae: Pharaoh ants have 12-segmented antennae that are usually shorter than the body.
• Nesting behaviour: Pharaoh ants are known for their ability to establish multiple nesting sites, which can make them difficult to control. They often nest in hard-to-reach locations such as wall voids, electrical boxes, and inside appliances.
• Behaviour: Pharaoh ants are known for their erratic and fast-moving behaviour. They are often seen in trails, searching for food or new nesting sites. They are also known to “bud” or split off into new colonies when threatened.

If you suspect that you have a Pharaoh ant infestation, it is important to seek the assistance of a pest control professional for proper identification and treatment. Effective control of Pharaoh ants typically requires a multi-pronged approach, including identification of nesting sites, baiting, and exclusion measures such as sealing cracks and gaps in walls and floors.

Preventing Pharaoh ants from entering your home or building can be challenging, but there are some steps you can take to reduce the likelihood of an infestation. Here are some tips on how to prevent Pharaoh ants:

1. Practice good sanitation: Pharaoh ants are attracted to food and moisture sources, so keeping your home or building clean and dry is important. This includes cleaning up spills promptly, storing food in airtight containers, and regularly emptying garbage cans.
2. Seal entry points: Pharaoh ants can enter buildings through small cracks and gaps in walls, floors, and foundations. Seal any entry points with caulking or weatherstripping to prevent ants from entering.
3. Remove potential nesting sites: Pharaoh ants nest in warm, humid places such as wall voids, electrical boxes, and inside appliances. Keep these areas dry and remove any clutter that could provide a nesting site.
4. Avoid DIY pest control: Attempting to control Pharaoh ants on your own with DIY methods such as sprays or baits can make the problem worse. The ants may scatter and establish multiple new colonies in response to the disturbance.
5. Work with a pest control professional: If you suspect that you have a Pharaoh ant infestation, it is important to seek the assistance of a licensed pest control professional. They have the knowledge and tools to identify the ant species and develop an effective control plan.

Following these prevention tips can reduce the likelihood of a Pharaoh ant infestation in your home or building. Early detection and intervention are key to controlling ants before they become a major problem.
