Things you should know about Ants!
Ant control and management can be easier said than done in Cape Town. But, there are some things you should know about how ants’ social activities can lead to giant headaches for you and your office :
- Entry: Ants can enter through even the tiniest cracks, seeking water and sweet or greasy food substances in the kitchen pantry or storeroom areas.
- Scent trails: Ants leave an invisible chemical trail which contains pheromones for others to follow once they locate the food source.
- Nest locations: They can nest about anywhere in and around your house; in lawns, walls, stumps, even under foundations.
- Colony size: Colonies can range from 300,000 to 500,000, and whole colonies can uproot and relocate quickly when threatened.
- Colony Lifetime: A colony can live a relatively long lifetime. Worker ants may live for seven years, and the queen may live as long as 15 years.
Ant Life Cycle
The ant life cycle has four distinct and very different life stages: egg, larvae, pupae and adult. This is known as complete metamorphosis. It generally takes from several weeks to several months to complete the life cycle, depending upon the ant species and environmental factors.
A female ant that successfully mates with a male ant will become a queen ant that lays eggs. Fertile queens select a sheltered place to begin a nest (colony) and begin laying eggs. Ant eggs are very small – only about a half of a millimetre in diameter. The eggs are also oval, white and transparent.
After about 1-2 weeks in the egg stage, a grub-like, legless ant larvae hatches. This stage has a voracious appetite, and the adult ants spend much of their time feeding the larvae with food and liquids they digest and regurgitate.
After the larvae moult and shed their skin, they change into the pupal stage. Pupae appear somewhat like adults except their legs and antennae are folded and pressed against the pupal body. Initially, ant pupae are usually white but slowly become darker in colour as they age. Depending upon the ant species, pupae may be housed in a protective cocoon.
Once the pupal stage is complete, the adult ant comes on the scene. At the time of emergence, the adult ant is fully grown but darkens in colour as it ages. Adult ants are one of three different colony castes; queens, workers or males. Queens are fertile females that lay all the eggs in a colony. Workers are females that do not reproduce, but do gather food; feed the larvae; keep the maintenance and cleanliness of the nest. Workers are wingless, and it is the worker stage that is seen foraging around for food or defending the colony from intruders. The male ants are winged, but their only job is to mate with the queens during the swarming process.
