Interesting facts about ants
  1. Like all insects, ants have six legs. Each leg has three joints. The legs of the ant are very strong so they can run very quickly. If a man could run as fast for his size as an ant can, he could run as fast as a racehorse. Ants can lift 20 times their own body weight. An ant brain has about 250 000 brain cells. A human brain has 10,000 million so a colony of 40,000 ants has collectively the same size brain as a human.

  2. The average life expectancy of an ant is 45-60 days. Ants use their antenae not only for touch, but also for their sense of smell. The head of the ant has a pair of large, strong jaws. The jaws open and shut sideways like a pair of scissors. Adult ants cannot chew and swallow solid food. Instead they swallow the juice which they squeeze from pieces of food. They throw away the dry part that is left over. The ant has two eyes, each eye is made of many smaller eyes.

  3. They are called compound eyes. The abdomen of the ant contains two stomachs. One stomach holds the food for itself and second stomach is for food to be shared with other ants. Like all insects, the outside of their body is covered with a hard armour this is called the exoskeleton. Ants have four distinct growing stages, the egg, larva, pupa and the adult. Biologists classify ants as a special group of wasps. (Hymenoptera Formicidae) There are over 10000 known species of ants. Each ant colony has at least one or more queens.

  4. The job of the queen is to lay eggs which the worker ants look after. Worker ants are sterile, they look for food, look after the young, and defend the nest from unwanted visitors. Ants are clean and tidy insects. Some worker ants are given the job of taking the rubbish from the nest and putting it outside in a special rubbish dump! Each colony of ants has its own smell. In this way, intruders can be recognized immediately. Many ants such as the common Red species have a sting which they use to defend their nest.

  5. The common Black Ants and Wood Ants have no sting, but they can squirt a spray of formic acid. Some birds put ants in their feathers because the ants squirt formic acid which gets rid of the parasites. The Slave-Maker Ant (Polyergus Rufescens) raids the nests of other ants and steals their pupae. When these new ants hatch,they work as slaves within the colony. The worker ants keep the eggs and larvae in different groups according to ages.

  6. At night the worker ants move the eggs and larvae deep into the nest to protect them from the cold. During the daytime, the worker ants move the eggs and larvae of the colony to the top of the nest so that they can be warmer. If a worker ant has found a good source for food, it leaves a trail of scent so that the other ants in the colony can find the food. Army Ants are nomadic and they are always moving. They carry their larvae and their eggs with them in a long column.

  7. The Army Ant (Ecitron Burchelli) of South America, can have as many as 700,000 members in its colony. The Leaf Cutter Ants are farmers. They cut out pieces of leaves which they take back to their nests. They chew them into a pulp and a special fungus grows it. Ants cannot digest leaves because they cannot digest cellulose. Many people think ants are a pest but I like them. To stop them coming into my kitchen I put some sugar outside. They they have so much to eat that they are not interested in coming into my kitchen.
Pharaoh Ants:

Because of their very small size, Pharaoh ants are often considered a minor pest but if they are ignored they can multiply rapidly and become a serious risk to health. They are one of the most difficult pests to eliminate in structures requiring the training and experience of a professional. Pesticide sprays will only worsen the problem. Nests up to 300,000 workers with multiple queens will nest in wall and cabinet voids, behind baseboards, behind refrigerator insulation, inside hollow curtain rods, or in the folds of sheets, clothes, or paper. They follow plumbing and wiring and have been found in light switches and electrical outlets. In colder climates they prefer to nest in heated buildings.

Colonies are very mobile; workers, along with larvae, pupae, and even a few queens, may move to new locations if disturbed or if colony becomes too large. New nests can be formed by "budding" with as few as 5 workers, 10 preadults, and one queen migrating from the original colony. Development time (egg to adult) for workers is about 38 days at 80 degrees F. Workers live about 9-10 weeks, with only up to 10% out foraging at any given time. Queens live about 4-12 months, and males die about 3-5 weeks after mating.

Health Risk:

In some areas, this ant has become a major pest of residences, food plants, factories, office buildings, apartments, and hospitals. Infestations in hospitals have become a chronic problem in Europe and the United States where burn victims and newborns are subjected to increased risk because the Pharaoh ant can transmit over a dozen pathogenic pathogens. Pharaoh ants have been observed seeking moisture from the mouths of sleeping infants and from in-use IV bottles.


Control of Pharaoh ants is difficult, due to their nesting in inaccessible areas. Treatment must be thorough and complete at all nesting sites, as well as the foraging area. Thus, treatment must include walls, ceilings, floor voids, and electrical wall outlets. Baits are now the preferred method of control for Pharaoh ants and several baits (insecticides) are labelled for indoor ant control. A Pharaoh ant infestation of a multifamily building requires treatment of the entire building to control the infestation. Ants nesting on the outside may be controlled by also using a perimeter barrier treatment.

Baits cannot be placed in just any location and be expected to work. Pharaoh ant trails and their resources (both food and water) must be located for proper placement of baits and effective control. Non-repellent baits (such as boric acid, hydramethylon or sulfonamide) should be used, as repellent baits can worsen the situation by causing the colony to fracture and bud. As a result, ant activity will briefly diminish as the new colonies establish themselves, then again become a problem as the foragers resume activity in a new location.
