Common Ant Species in Johannesburg

Ants are one of the most common pests that property owners in Johannesburg encounter. Whether it’s a trail leading to your kitchen or an outdoor swarm disrupting your garden, ants are a persistent problem that can quickly get out of hand. Many people try to manage the issue themselves, using store-bought sprays and traps, but these solutions often provide only temporary relief.

Without understanding the specific species of ant you’re dealing with, it’s nearly impossible to effectively eliminate the infestation.
The truth is, different ant species require different control methods. What works for one type may not work for another. Over the years, I’ve seen countless clients struggle with recurring ant problems simply because they didn’t know what they were up against. In this guide, we’ll explore the most common ant species found in Johannesburg, how to identify them, and the best strategies for keeping them out of your property for good.

Identifying Common Ant Species in Johannesburg

Understanding the types of ants that may invade your property is crucial in developing an effective pest control strategy. Johannesburg is home to several ant species, each with its own habits, nesting preferences, and food sources. Let’s take a closer look at the most common culprits.

1. Argentine Ants (Linepithema humile)

Argentine ants are one of the most prevalent ant species in Johannesburg. They are small, measuring about 2.2 to 2.8 millimetres in length, and are light to dark brown in colour. Argentine ants are known for their aggressive behaviour and ability to displace native ant species. They are particularly drawn to sugary substances but will also feed on proteins and fats.

These ants typically nest outdoors in moist environments, such as under rocks, logs, or in the soil. However, during dry or wet weather, they will seek shelter indoors, where they can become a significant nuisance. Argentine ants are difficult to control because they form large colonies with multiple queens, making it challenging to eradicate them completely without professional help.

2. Black House Ants (Ochetellus glaber)

As their name suggests, black house ants are tiny black ants that commonly invade homes and businesses in search of food. They are slightly larger than Argentine ants, with a length of about 2.5 to 3 millimetres. These ants are particularly attracted to sweet foods, which is why they are often found in kitchens and pantries.

Black house ants are known for their persistent foraging behaviour, establishing long trails from their nest to the food source. Their nests are typically located outdoors in soil, under stones, or within walls. While they don’t pose a direct health risk, their presence can be incredibly frustrating, and they can contaminate food supplies.

3. Carpenter Ants (Camponotus spp.)

Carpenter ants are one of the largest ant species found in Johannesburg, with workers ranging from 6 to 12 millimetres in length. They are black or dark brown and have a noticeable segmented body. Unlike other ant species, carpenter ants don’t eat wood but instead excavate it to create their nests. This behaviour can cause significant structural damage to properties, particularly if left untreated.

Carpenter ants are typically found in damp or decaying wood, such as in wall voids, roof eaves, or wooden beams. While they are often associated with outdoor nests, they can also establish colonies indoors, especially in areas with moisture problems. Due to the potential damage they can cause, it’s crucial to address a carpenter ant infestation as soon as possible.

4. Pavement Ants (Tetramorium caespitum)

Pavement ants are small, brownish-black ants that are commonly found nesting under sidewalks, driveways, and building foundations. They measure about 2.5 to 3 millimetres in length and are known for the distinct mounds of soil they create near their nests. Pavement ants are omnivorous, feeding on a variety of foods, including sweets, proteins, and grease.

While pavement ants primarily nest outdoors, they can enter homes and businesses in search of food. Once inside, they can become a persistent nuisance, especially in kitchens and food storage areas. Their nests are often difficult to locate, making it challenging to eliminate them without professional intervention.

5. Sugar Ants (Camponotus consobrinus)

Sugar ants are a common sight in Johannesburg, especially in homes and gardens. They get their name from their preference for sweet foods, but they will also consume proteins and fats. Sugar ants vary in size depending on their role within the colony, with workers ranging from 2 to 15 millimetres in length. They are usually black or brown with orange-brown bands on their bodies.

These ants are nocturnal, meaning they are most active at night. They typically nest outdoors in soil, under rocks, or in decaying wood. However, they will readily enter homes if they find a reliable food source. Sugar ants are not only a nuisance but can also contaminate food supplies, making effective control measures essential.

Preventing Ant Infestations

Understanding the behaviour and nesting habits of these common ant species is key to preventing infestations in your home or business. Here are some strategies to keep ants at bay:

1. Maintain Cleanliness

Ants are attracted to food and water sources, so maintaining a clean environment is essential. Ensure that food is stored in sealed containers, spills are cleaned up immediately, and garbage is disposed of regularly. Pay special attention to areas where food is prepared and consumed, as these are prime targets for ants.

2. Seal Entry Points

Ants can enter your property through the smallest cracks and gaps. Inspect your home or business for potential entry points, such as gaps in windows, doors, and walls, and seal them with caulk or weatherstripping. Pay particular attention to areas around pipes and utility lines, as these are common entry points for ants.

3. Eliminate Moisture Sources

Many ant species are attracted to moisture, so addressing any water leaks or damp areas in your property is crucial. Fix leaky pipes, ensure proper ventilation in damp areas like basements and bathrooms, and consider using a dehumidifier if necessary.

4. Regular Inspections

Regular inspections by a professional pest control service can help identify and address ant problems before they become severe. A trained technician can locate nests, identify the ant species, and implement targeted control measures to keep your property ant-free.

FAQ: Common Questions About Ant Species in Johannesburg

Q1: How can I tell which species of ant is infesting my property?

A: Identifying the ant species can be challenging, as many species look similar. However, observing their size, colour, and behaviour can provide clues. For a precise identification, it’s best to consult a professional pest control service.

Q2: Why do ants keep coming back even after I’ve treated them?

A: Ants can be persistent because many DIY treatments only target the ants you see, not the colony. If the colony is not eliminated, ants will continue to invade your property. Professional treatments are more effective as they address the root cause of the infestation.

Q3: Are ants dangerous to my property?

A: While most ants are not directly harmful, species like carpenter ants can cause structural damage by excavating wood for their nests. Additionally, ants can contaminate food and surfaces, posing a hygiene risk.

Q4: What should I do if I find ants in my kitchen?

A: Start by cleaning up any food or spills and removing potential attractants. Seal entry points and consider setting up ant baits to target the colony. If the problem persists, contact a professional pest control service for a thorough inspection and treatment.

Q5: How often should I have my property inspected for ants?

A: It’s recommended to have your property inspected at least once a year, especially if you’ve had issues with ants in the past. Regular inspections help catch and address potential infestations before they become severe.
