Wasps – Life Cycle and Control

Although useful, wasps can be very dangerous when they show up in and around your home. Unlike bees which only sting once, a wasp is capable of stinging several times repeatedly.  While painful, most people will generally recover from a wasp sting within 24hrs with only minor complication. For a small percentage of the population however wasp stings can cause an anaphylactic shock which could be fatal.

Wasps come in various sizes and colours depending on the species. But there is one feature that is common to all the species: a pointed lower abdomen and a very narrow waist known as a petiole that separates the thorax from the abdomen

Wasps fall into one of two categories: 1) social wasps and 2) solitary wasps. Adult solitary wasps will mostly live alone with the majority not constructing nests. Social wasps, in contrast, exist in large colonies comprising of thousands of individuals in a single nest. It is the latter type of wasps that can be most problematic when they invade your home. They will build a nest inside or around your home with thousands of wasps greatly jeopardising your family’s safety

Social wasps build their nests in low traffic areas where they will not be disturbed. The attic is one of their favourite spots as it is dry and warm in addition to being rarely used. Other potential habitats include wall cavities, under a building’s eaves and roof spaces. It is here that a queen will construct a basic nest from chewed wood pulp and saliva.

The life cycle of the wasp

Once a fertile queen mates with a male wasp, she stores the sperm cells in an inactive state inside a tightly packed ball inside her body. These cells will be kept dormant until the queen is ready to reproduce.

The queen, when ready, will identify a suitable area to set up a nest. Using chewed wood and saliva, she will construct a basic nest roughly the size of a walnut and lay her first eggs inside. Once the eggs hatch into larvae, she will forage and feed them with dead insects. The larvae in return excrete a sweet substance on which the female wasp feeds on.

Once mature enough the larvae will pupate and then emerge as adults. All fertilized eggs hatch into females while all unfertilized eggs will hatch into males, otherwise known as drones. The newly produced female wasps will then take over nest building duties and provide for the queen’s larvae. The drone’s only purpose in life is to mate. Ordinary wasps will live for approximately 30 days while a queen will live for about twelve months.
