In South Africa, we have two common species of ants called the Pharaohs ant and the common black ant (The former Monomorium pharaonis, and the latter Lasius niger). Of the two species, the Pharaoh Ant is the species that do pose a risk to one’s health due to the habitat they can occur in which can be refuse areas, drains, and sewers which in turn is a high risk in transmitting various pathogens.
Black ants generally are of nuisance value to many residents and if not treated correctly can cause damage to ones paving, whereby they tunnel under the brickwork and deposit heaps of soil thus causing the paving to collapse. As well as being a nuisance value, in certain circumstances in their vast numbers and nesting habits can destroy plants and grass growth.
Ant, this is the common name for members of a family of hymenopteran insects known for highly organised social life ants a wingless caste. At least 8800 species exist, with most found in the tropics. Ants are found throughout the world except in the Polar Regions and at the very highest altitudes. True ants are entirely different from the so-called white ants or termites, which constitute a different order. These ants are commonly referred to as black or red ants in South Africa. Both species follow a similar life cycle and thus a similar control programme would be effective, this will follow under control measures.
Identification & Physical Description
Pharoah ants are small, approximately 2mm long. They are yellow to light brown in color. Pharoah ants have poor eyesight.
Life Cycle
The full life cycle of Pharoah ants takes about 42 days. Queens often lay 12 eggs at a time but can potentially lay as many as 400. Queens only live for 4-12 months. Workers live for a couple of months and usually die soon after mating.
Food & Water
Pharaoh ants eat food of all types, especially sweets. They will also eat other insects,baked goods, sugar, jellies, syrup, honey, fruit juice, soft drinks, grease, starch, dead insects and even shoe polish, silk, rayon and rubber
Social Behaviour
The Pharaoh ant colony consists of queens, males and workers.Pharaoh ants have large colonies and they are easy to spot but very difficult to locate their nests.
Nesting
Pharaoh Ants like to nest in warm areas. Their nests are usually hidden, and can forage far away from the nest with trails marked by trail pheromones.
Health Risks
Pharaoh ants spread pathogens which include salmonella and Streptococcus. Pharaoh ants are particularly dangerous in hospitals because they contaminate patient wounds.
Identification & Physical Description
Argentine ants are wingless worker ants, which are 1/12 to 1/8 cm long. They are light to dark brown in color with a single node in the waist. The Argentine queen ant is 1/6 to ¼ cm long. The colony tends to travel in trails.

The entire life cycle of the Argentine ant from egg to adult takes 2 to 3 months. As adults, Workers live a month or more. Queens live up to 10 years. Larvae emerge approximately 28 days later. The larval stage lasts from 11 to 60 days, followed by a pupal stage of 10 to 25 days.
Food & Water
Argentine Ants prefer sweet foods and are often found tending aphids or scale insects on plants, using them as a source of honeydew. Even though worker ants eat sweet treats, they gather protein/grease-based foods to bring back to the queens and larvae.
Social Behaviour
Argentine ants are very dominant and can be very territorial which makes them take over areas driving out any other native species of ants.
Nesting
Argentine ants nest in cavities at the base of shrubs and trees. Their nests are shallow, measuring up to 20 cm in depth in open habitats.
Health Risks
The biggest health risk associated with an Argentine ant infestation is food contamination because they crawl over rubbish bins, dead animals, and sewage looking for food and can bring germs that cause diseases like dysentery.

The queen can potentially lay up to 290 eggs per month to hatch 2-4 weeks later.
Worker ants live for approx. 1 year
Queen ants live for several years
Food & Water
Coastal Brown Ants are both carbohydrates and protein eaters but do have a preference to oily proteins. They feed on sweet liquids.
Social Behaviour
These ants are a very invasive breed. They create super colonies and Multiply queens so they can reproduce rapidly
Nesting
Coastal brown ants are soil-nesting ants that displaces soil and leaves tell-tale mounds of soil next to the nest opening.
Health Risks
The coastal brown ant does not pose any health risks to humans nor does it cause structural damage. The ant can only bite when their nest had been distrurbed and the bite is not reported to poise any health hazards.
Identification & Physical Description
Fire ants are reddish-brown with a darker abdomen. Fire ants can range in size from 1/16 – ¼ cm long depending on the species. Fire ants have noticeable waists with clubbed or bent antennae. They are known to have 6 legs and stingers.

Identification & Physical Description
Queen phenotype 9 mm long, glossy black color but appears to have slight brown stripes on her abdomen. The queen can reach 6-9mm in length and is smaller than a new queen. After a queen mates, she removes her wings and digests her wing muscles as food over the winter.
Male phenotype 3.5–4.5 mm long, slim, colour black. Only produced by queens when the nuptial flights are approaching. They appear with a dark glossy body with a different shape from the workers, almost resembling a wasp in appearance. They have wing muscles which stand out from the rest of the body. They are 5-7mm long and have delicate wings.
Worker phenotype 3–5 mm long, workers are dark glossy black. As the colony gets older it has been known for workers to increase in size over generations.
Major phenotype Lasius niger do not create a major caste.

How ant pest control works
Control measures
A Flick inspector/ technician will undertake a thorough inspection of the property during his routine service call to determine what control measures would be put in place that will control the ant infestation. The treatment would entail offering regular follow up services to the garden areas- which includes either a spray insecticide application to the garden, all lawn areas, flower beds and nests within the paved areas. Alternative application methods include a granular based application to high activity areas within the garden, along with a gel application in or around one’s home. These treatments are guaranteed between services, i.e. if there is re infestation between routine services, Flick would return at no extra charge to re treat all infested areas.
Nest holes will also be injected using this pesticide under high pressure. Due to the rapid breeding and movement of black ants, it is recommended that if one lives in a complex that the entire complex be treated simultaneously to avoid any possible cross infestation from occurring within the complex. It is essential that all residents participate and have their respective units treated when the service is due. This further will prevent black ants from cross infesting their units.
A gel application can also be used in highly infested areas or sensitive areas where spray applications cannot be undertaken. This works by way of the ants being attracted to the gel by the incorporated attractant within the gel, the ants then feed on this and further take the gel back to their nests.
All our chemicals are approved by the SABS and are applied by our service men that are registered with The Department of Agriculture.
Identifying ant infestations
ANT PATHWAYS – You may find trails of inside your home or workplace. Certain types of ants leave behind a trail of pheromones that help other ants find their way to the food or water source.
VISIBLE ANTS – You can see large numbers of ants in your home or workplace. If you spot them near food preparation areas the situation can escalate very quickly.
ANT NESTS – You find loose heaps of soil deposits.
Frequently Asked Questions about Ant Pest Control
This is a very good question but is not as straightforward to provide the answer on the costs. The cost of an ant treatment depends on a number of factors including, what method of application is utilized, the locality of the site to be treated, labour, chemical type and a number of other factors that contribute towards a price, whether it be for a domestic or commercial client, and lastly also dependant on the level of infestation, and how often a service would be required for effective control. Our trained Sales agents will be able to provide you with a quotation when requested.
There are various control measures that we can undertake to control an ant infestation. The treatment type varies from site to site, and if it’s a residential or a commercial premises. Flick recommends that regular services are conducted on either a quarterly, bi-monthly, six weekly or monthly basis, dependant on the environment one is treating, and what control measures are required. Our regular contractual services are guaranteed from service to service, that is- if there is a re-infestation of ants between regular services, that Flick will return at no charge to treat the problem areas identified and reported. If a once-off service is carried out, our standard guarantee period of 30 days (one calendar month) will apply.
An ant control service can vary from approximately 30 minutes up to a few hours or even up to a day or a few days, all depending on the size of the premises being treated. Treating an average-sized home along with the garden with a size less than 1000m2 would take approximately one and a half to two hours to undertake. This will vary from site to site with factors such as the level of infestation, areas to treat, access, as well as safety factors to consider etc.
Flick undertakes pest control services to control the pest at hand, and this being ants. We make use of various formulations, including spray applications, gel baits and dry granular applications.
