Common Types of Ants

From Carpenters to Field ants, each species possesses unique traits and behaviors. Understanding these differences paints a clearer picture of managing and preventing unwanted infestations. Let's explore these diverse species that may tread within our living spaces.

1. Carpenter Ants

Carpenter ants are a homeowner's silent nightmare.

Physical Appearance

These ants are rather large, typically 1/4 to 3/8 inch long. You'll usually spot them in solid black, but some may have reddish or brownish hues.

Habitat and Nesting Preferences

Carpenter ants are true craftsmen. They prefer wood softened by moisture or decay to carve out galleries for nesting, making our homes their prime target.

What They Are Attracted To

Their affinity for damp wood draws them to areas like the kitchen or bathroom and any damp timber around the property, such as leaking pipes.

Potential Threats

While they don't consume wood like termites, their excavation work can eventually lead to structural damage.

Ways to Control the Colony

• Identify and address any moisture issues you may have.
• Use non-repellent sprays designed for carpenter ants.
• Apply gel bait – carpenter ants cannot resist it.

Tips for Prevention

• Regularly check for and repair water leaks or moisture problems.
• Trim vegetation away from the house, as it can serve as an entry point.
• Stack firewood well away from the property since it's a favorite nesting spot.

2. Pavement Ants

Pavement ants are known for their stealthy settlement in the crevices of our daily lives.

Physical Appearance

These small ants range from 1/16 to 1/8 inch in size and typically appear dark brown to black with grooved parallel lines on their head and thorax.

Habitat and Nesting Preferences

As their name suggests, they love to nest beneath pavements, sidewalks, or in the cracks of building foundations. They can also be found between walls or under insulations indoors.

What They Are Attracted To

Pavement ants have a sweet tooth for sugary substances and greasy materials and are drawn to accessible food sources like crumbs or spills.

Potential Threats

Although not a direct threat to wood structures like carpenter ants, their infestations within and around the property can be quite a nuisance.

Ways to Control the Colony

• Seal any foundation cracks and gaps where they could enter from.
• Manage food spills promptly.
• Apply ant baits, pesticides, or diatomaceous earth in targeted areas.

Tips for Prevention

• Keep your property clean of food debris and excess moisture.
• Store food in sealed containers.
• Maintain the landscape around your property to limit them from nesting close to your foundation.

3. Pharaoh Ants

Named for the mistaken belief that they were one of Egypt's plagues, Pharaoh ants are a pest that demands attention.

Physical Appearance

These ants are tiny, a mere 1/16 inch in length, and are often light yellow to red, with a distinctive darker abdomen.

Habitat and Nesting Preferences

Pharaoh ants prefer warm and humid environments. They nest in well-protected, hidden spaces, often behind walls, furniture, or appliances.

What They Are Attracted To

Like most ants, Pharaoh ants follow the trail of food. They're drawn to sugary sources, dead insects, and greasy or fatty foods.

Potential Threats

Pharaoh ants are notorious for their potential to spread disease-causing bacteria, posing a public health risk.

Ways to Control the Colony

• Use bait stations specifically designed for Pharaoh ants.
• Ensure there's no accessible food around.

Tips for Prevention

• Keep your property clean and free from accessible food.
• Maintain humidity levels, as Pharaoh ants prefer humid environments.

Originating from South America, they prefer moist surroundings near a food source. They settle in a wide variety of locations, from nests outdoors to moisture-laden spaces inside your home.

What They Are Attracted To

Argentine ants favor sweet foods like fruit juices, but they eat almost anything, including meats, eggs, oils, and fats.

Besides being a nuisance, Argentine ants are infamous for protecting aphids from predators—impacting the health of plants in your garden.

Ways to Control the Colony

• Apply ant baits and pesticides around targeted spots.
• Keep the house tidy for food scraps or spills.
• Address any structural moisture immediately.

Tips for Prevention

What They Are Attracted To

Crazy ants search for various food sources, including sweets, proteins, and seeds - often found in kitchen pantries and the great outdoors.

They nest both indoors and outdoors, often repurposing abandoned termites or carpenter ant nests or hollowing out softwood. Moist wood and areas near plumbing are particularly attractive to them.

What They Are Attracted to

These ants primarily seek out sweet foods left out in the open, such as fruit, sugary liquids, and other sugar-based products.
