    South African Rodents

    This list is non-exhaustive

    A rodent can contribute to the spread of disease both directly and indirectly and can do a great deal of structural damage to a building. Rats are incredibly persistent creatures that will find their way into your home or business through the tiniest of spaces to seek food and warmth.

    The effects of a rat infestation in your home can be far reaching and very troublesome. They can chew through insulation, floor supports, walls and even electrical cables. A rodent’s burrowing ability can undermine and even cause a collapse of retaining walls and other similar structures.

    Identification & Physical Description

    Black rats are long and thin rodents that have large eyes and ears, a pointed nose and a scaly tail. They have soft and smooth fur that is brown with intermixed spots of black. Their undersides are often white, gray or black.

    Life Cycle

    The life cycle of a black rat can be from a year to 18 months. During this period, the female can typically breed 6 times with an average litter of 6-8.

    Food & Water

    Black rats are omnivores and eat a wide range of foods, including seeds, fruit, stems, leaves, fungi, and a variety of invertebrates and vertebrates.

    Social Behaviour

    Black rats tend to live in polygynous groups with multiple males and females. These animals strip bark off of trees, contaminate human food sources, and are overall pests.


    Black Rats are born in a nest in a litter of 6-8 young. The nest is often in a secure place with nesting debris such as in an attic in the insulation. They are born tiny and hairless (pinkies), with eyes sealed shut.

    Health Risks

    Black rats can carry a number of pathogens, of which bubonic plague , typhus, Weil’s disease, toxoplasmosis and trichinosis are the best known.

    Interesting Facts

    Medieval Pope Gregory IX considered cats to be the ‘incarnation of Satan’. Leading to a mass killing of cats, causing the rat population to swell, quickening the spread of the Black Death.

    Identification & Physical Description

    Brown or dark grey color, and the underside a lighter brown to light grey.

    The head and body length ranges from 15 to 28 cm while the tail ranges in length from 10.5 to 24 cm, therefore being shorter than the head and body.

    Adult weight ranges from 140 – 500g. Exceptionally large individuals can reportedly reach 900 -1,000g but are not expected outside of domestic specimens. Reports of rats attaining sizes as big as cats are exaggerations, or misidentifications of larger rodents, such as the coypu and muskrat. In fact, it is common for breeding wild brown rats to weigh (sometimes considerably) less than 300g.

    Life Cycle

    The gestation period is 21 days, and litters can number up to 14. They reach sexual maturity in about five weeks and the maximum life span is three years.

    Food & Water

    They will eat any food that is left unprotected. Brown Rats have also been known to eat grain or kill insects, water creatures such as snails, fish and mussels, small birds and reptiles for food.

    Social Behaviour

    Brown rats are capable of producing ultrasonic vocalizations. As pups, young rats use different types of ultrasonic cries to elicit and direct maternal behavior.  Although pups will produce ultrasounds around any other rats at 7 days old, by 14 days old they significantly reduce ultrasound production around male rats as a defensive response. Adult rats will emit ultrasonic vocalizations in response to predators or perceived danger. The frequency and duration of such cries depends on the sex and reproductive status of the rat. The female rat will also emit ultrasonic vocalizations during mating.

    Brown rats also produce communicative noises capable of being heard by humans. The most commonly heard in domestic rats is bruxing, or teeth-grinding, which is most usually triggered by happiness, but can also be ‘self-comforting’ in stressful situations, such as a visit to the vet. The noise is best described as either a quick clicking or ‘burring’ sound, varying from animal to animal.

    In addition, they commonly squeak along a range of tones from high, abrupt pain squeaks to soft, persistent ‘singing’ sounds during confrontations.

    Rats are territorial animals, meaning that they usually act aggressively or scared of strange rats. Rats will fluff up their hair, hiss, squeal, and move their tails around when defending their territory. Rats will chase each other, groom each other, sleep in group nests, wrestle with each other, have dominance squabbles, communicate, and play in various other ways with each other. Huddling is an additional important part of rat socialization. Huddling is often supposed to have a heat-conserving function. Nestling rats especially depend on heat from their mother, since they cannot regulate their own temperature.


    Brown rats in particular will dig rat holes in areas of a garden to create rat burrows where they will nest, store food and raise young rats.

    Health Risks

    Brown Rats carry diseases which can be easily spread to humans, rats transfer diseases like Leptospirosis or Weil’s disease, Salmonella, Listeria, Toxoplasma gondii and Hantavirus. Brown Rats can also inflict a great amount of structural damage.

    Interesting Facts

    Rats succumb to peer-pressure, just like humans. Brown rats are prone to disregard personal experiences in order to copy the behaviour of their peers. The urge to conform is so strong that they will even choose to eat unpalatable food if they are in the company of other rats who are eating it.

    The only brown rat-free areas in the world are the continent of Antarctica, the Arctic, some isolated islands, the Canadian province of Alberta, and certain conservation areas in New Zealand.

    Identification & Physical Description

    House mice have an adult body length (nose to base of tail) of 7.5–10 cm and a tail length of 5–10 cm. The weight is typically 40–45 g. In the wild they vary in color from grey and light brown to black. They have short hair and some, but not all, sub-species have a light belly. The ears and tail have little hair.

    Life Cycle

    House mice usually live less than one year in the wild, due to a high level of predation and exposure to harsh environments. In protected environments, however, they often live two to three years.

    Food & Water

    A mouse eats seeds, cereal grains, or sweets but will eat almost anything. Mice do not need much water; they get most of their water requirements from their food

    Social Behaviour

    The social behavior of the house mouse is not rigidly fixed into species-specific patterns but is instead adaptable to the environmental conditions, such as the availability of food and space. This adaptability allows house mice to inhabit diverse areas ranging from sandy dunes to apartment buildings.

    House mice have two forms of social behaviour:

    1. House mice in buildings and other urbanized areas with close proximity to humans are known as commensal. Commensal mice populations often have an excessive food source resulting in high population densities and small home ranges. This causes a switch from territorial behaviour to a hierarchy of individuals.  The social unit of commensal house mouse populations generally consists of one male and two or more females, usually related. These groups breed cooperatively, with the females communally nursing.
    2. In open areas such as shrubs and fields, the house mouse population is known as noncommensal. These populations are often limited by water or food supply and have large territories. Aggression is higher in noncommensal populations.

    Both commensal and noncommensal house mouse males aggressively defend their territory and act to exclude all intruders. Males mark their territory by scent marking with urine. In marked territories, intruders showed significantly lower aggression than the territory residents. House mice show a male-biased dispersal; males generally leave their birth sites and migrate to form new territories whereas females generally stay and are opportunistic breeders rather than seasonal.


    The mouse nest is made usually of scrap materials, gathered after a lot of chewing on various fabric the nest provides shelter and security for female mice to give birth to the new litter.

    Health Risks

    While the common house mouse is not as dangerous to your health they can still spread disease, such as hantavirus, salmonellosis and listeria through their urine, droppings, saliva and nesting materials.

    How rodent pest control works


    A qualified Flick inspector will call at a time to suit you, to carry out a thorough inspection. Years of experience in the field and specialised training have equipped him to know just what to look for. He will then identify the rodent species and size of
    the infestation, their food and water sources and method of access. All these are essentials that must be known to decide on the best control measures.

    He will provide you with a comprehensive obligation free quotation for treatment.

    This of course carries the Flick Warranty – if re-infestation occurs during the warranty period, additional treatment will be provided free of charge.


    Sanitation and hygiene are absolute musts if the control program is to be effective. The elimination of rat harbourage locations, food and water sources and the general cleanliness of the area are all essentials. Garbage heaps, old machinery, timber piles, weed growth and general litter should be removed. Garbage must be kept in rat-proof cans with tight-fitting lids and a well-organised and supervised cleaning and maintenance plan must be adhered to. Here again, the Flick inspector can help. He will provide expert advice on the action required to minimise the risk of re-infestation.


    The suspicious and cunning nature of rodents can result in the treatment being a very specialised process. Most treatment methods involve the laying of special baits depending upon the type, size and food source of the infestation. Other methods such as tracking powders and traps may also be used.

    Flick Pest Control has developed a wide variety of bait types, which have all been thoroughly tested in the field and proven successful!. In situations where the rodent is not taking the bait or appears to have a resistance to it, the Biologists and Entomologists from the Company’s Technical Services Department will develop a “tailor-made” treatment method to suit the particular situation.

    The safety of humans and pets and the non-contamination of food and other materials is paramount. The controi method is always determined with these factors in mind.

    Tamper-proof rodent bait stations

    Rodents- namely rats and mice are year-round vermin that are not limited to one season of the year and do require ongoing control. We have various forms of rodent control measures that we can offer. Here we have our latest tamper-resistant rodent station.

    The rodent station is very versatile and can accommodate rodent bait blocks for control and monitoring purposes, as well as the option to use non-toxic blocks for HACCP-sensitive sites for monitoring purposes. The station can also fit a mechanical snap trap for non-toxic control purposes, or in circumstances that warrant it, the ability to have liquid bait within the bait station in secured cups that rodents would consume this from.

    Signs of a Rodent Problem

    The most obvious sign that a problem might exist is sightings of a single or multiple rodent.

    Rodent droppings are dark brown in a tapered, spindle shape – like a grain of rice.

    You might notice gnaw marks on wires, cabling or items.

    Some rats are known for burrow extensive tunnels for shelter, food storage and nesting.

    Most rodents will shred available materials such as insulation, cardboard and other soft items to make nests.

    Rodents leave foot and tail marks in dusty, less-used areas of buildings.

    Interesting rodent facts

    • Rodents do not vomit.
    • Rat baiting, a popular sport in 19th-century London, pitted a man or a dog against hundreds of rats. Jacko, a 13-pound bull terrier, set the record in 1862 when he killed 100 rats in 5 minutes, 28 seconds.
    • Rats do not sweat. They regulate their temperature by constricting or expanding blood vessels in their tails.
    • Rats don’t have gallbladders or tonsils, but they do have belly buttons.
    • A female rat can mate as many as 500 times with various males during a six-hour period of receptivity—a state she experiences about 15 times per year. Thus a pair of brown rats can produce as many as 2,000 descendants in a year if left to breed unchecked. (A rat matures sexually at age three to four months.) An average rat’s life span is two to three years.
    • A rat can tread water for three days and survive being flushed down the toilet. (And it can return to the building via the same route.)
    • A Hindu temple dedicated to the rat goddess Karni Mata in Deshnoke, India, houses more than 20,000 rats. Many people travel far to pay respect to the rats, which are believed to be reincarnations of Karni Mata and her clansmen.
    • A rat can go longer than a camel without having a drink of water.
    • Without companionship rats tend to become lonely and depressed.
    • The naked mole rat is unable to feel pain, is the only known thermoconforming mammal, is resistant to cancer, and possesses extraordinary longevity for a rodent.
    • Giant rats have been trained to sniff out 14,000 landmines and other unexploded arsenals. The rats, which undergo nine months training, are light enough to not trigger the explosives. They literally work for peanuts!
    • African giant pouched rats are trained to detect tuberculosis, which is the world’s second most fatal infectious disease. Although they currently are not an accepted standalone diagnostic tool, one rat can evaluate more samples in 10 minutes than a lab technician can evaluate in 1 day.
    • The first living creatures to go into orbit and return safely were 40 mice, two rats, a rabbit, some fruit flies, plants, and 2 dogs.
    • Rats ate 10% of Pablo Escobar‘s money per annum, amounting to $2.1 billion

    Frequently Asked Questions About Rodent Pest Control

    There are a number of factors to consider when looking at rodent control and providing a cost on a service, or the control measures needed for it.  As a result, the cost of the required control measures will vary from site to site, it is advised that the premises get assessed first with an inspection undertaken to look for the correct rodent control programme, and within the inspection, we would also look out for possible access points, high-risk areas, areas rodents would be attracted to, and places where rodents could possibly enter or harbour in. Housekeeping & proofing requirements would also be looked at that may be needed to be attended to by the client, and brought to your attention.

    Our trained Sales representative will be able to provide you with a quotation, in the form of a tailor-made quote for their control based on the above being undertaken.

    When Flick undertakes a rodent control service, whether regular treatment control measures are put in place, or if the client chooses to undertake a once-off service, Flick does provide a service guarantee, that is if there is re-infestation of the rodents in the areas of treatment between the initial date of service through to either the expiry date of the once-off service or if re-infestation of rodents is noticed/ reported during regular contractual services, this corrective action will be undertaken within the said written guarantee that the Flick consultant would have provided you.

    The treatment type varies from site to site, as well as if it’s a residential or commercial premises. Flick recommends that the premises get inspected first, and the correct recommendations and treatment plan be put forward to ensure effective control measures are implemented from the start. Typical service intervals can vary from as frequent as a weekly service, or bi-weekly service, however, services are typically undertaken monthly, six weekly, bi-monthly or at least once every quarter. But this again is dependent on the environment one is treating, the extent of the rodent infestation, the housekeeping/ stacking/ proofing standards on the site, the risk of cross infestation if the premises is near an area or adjoining favourable rodent breeding grounds, as well as taking all health and safety measures into account.

    A rodent control service can be divided into different segments- being the initial service, routine services for control purposes, or acute services (for when there are high levels of infestation and corrective action measures are needed to be put in place)

    An initial service may require the supply and installation of hardware, in the form of tamper-proof rodent bait stations, monitoring stations, or mechanical traps within the bait stations. An initial service when such type hardware will always take longer to undertake, as the Flick technician needs to plot where the rodent stations are installed, and further baited. Such service duration times are also dependant on the size of the premises being treated, and the quantity of tamper-proof stations being installed. A service could take as little as under an hour, ranging up to a few days if a really large quantity of rodent stations are required. Flick also offers tamper-proof bait stations that can be installed/ placed internally in high-risk areas, or even cardboard type rodent boxes can be baited with rodent blocks in lower risk/ low accessibility areas and are placed out of sight as much as possible. Ceilings are typically baited with cardboard type rodent bait stations with rodent wax blocks used for baiting purposes.

    With all these factors put into consideration, it does make it quite challenging to provide a definitive answer to the time period in how long a service will take.

    When treating for rodents, safety is our first priority that is taken into consideration. The safety aspect is considering all safety aspects, such as area of application, areas where various baits can be placed down or installed safely and avoid access/ contact is made by people or pets, especially children that they do not have direct access to the bait formulations. We make use of tamper-proof bait stations in outdoor environments, as well as certain indoor baiting applications to ensure no accidental access is obtained within the bait stations.

    Baits are placed out of the reach of people and pets within bait boxes or tamper-proof bait stations, where tamper-proof bait stations are further installed/mounted to a wall, in areas as identified and plotted either by our sales consultants or service technicians upon the initial inspection.

    When anyone whether it’s a pest control professional or an individual, and they are making use of any rodenticide, the product does contain an active ingredient in it to target or bait specifically against rodents. These poisons are manufactured with an LD50 ratio, and have various active ingredients in their formulation make up. Rodenticide baits can be either single feed or multi-feed baits that are provided by the various manufacturers of rodenticides. The latter being the multi-feed rodenticides are less volatile in their mode of action in controlling/ poising a rodent or rodent population in an area that is baited.

    In areas where there are risks pointed out to us by the client, or identified by Flick as a high risk area for known non-target animals such as owls or predatory animals that feed on rodents in a particular area in respect to the risk of secondary poisoning. In such circumstances, we will make use of either non-toxic trapping solutions in the form of snap traps (where possible to use and be checked/ serviced regularly), or we would make use of a specific rodenticide that is a multi-feed bait paste and has the least secondary poisoning effect to non-target animals that may prey on the rodents, and the product we would make use of is further endorsed by the Griffon Poison Centre for the use in baiting out tamper proof rodent bait stations, where possible non-target predatory animals may be exposed.

    All rodenticides Flick utilizes are SABS tested and approved and registered by the Department of Agriculture, and are applied/ baited in accordance to the manufacturer’s dosage rates.

    When you choose Flick as your company of choice to control your rodent problems, you will have the peace of mind that you are using a company that has the experience, the backup service, a good reputation, which has been in existence for over 50 years to honour their guarantee of service, and most importantly, that we only employ trained and registered service technicians, that are registered with the Department of Agriculture, as well as our Company having public liability insurance in place for any unforeseen circumstances.

    At the end of the day, you need to have peace of mind that the company you choose meets all these criteria to ensure that all safety protocols are followed and effective and reliable service is offered, of which you will obtain all of these when choosing Flick. Our service philosophy is that we believe in doing the job right the first time, and strive for service excellence in every aspect of our business.
