Certain termite species can swarm, leaving their colony in search of a new home.
The usual time for the termite swarmers season is just after spring or at the end of summer and usually after a rain event. In early summer the humid conditions often match the inside temperature of a termite nest. Often after a thunderstorm conditions are right for termite colonies to swarm. The release of the winged reproductives may be in the form of several small batches over a period of weeks or one or two large batches over a few days.
Most termites are Wingless, Sterile and Blind as the soldiers and workers do not need to develop eyes. Alates develop wings (and eyes) to leave the crowded termite nest in to start a new colony. They then shed their wings, find a mate and search for moisture, food and shelter. Once Alates have landed they will tunnel under the soil or find a piece of wood to nest in. The first batch of eggs are workers. These workers then take over the egg production and feeding the nymphs by regurgitating wood (your house if given the opportunity).
The maturity of a colony is another factor known to induce swarming activity.
As the colony matures it produces alate nymphs (winged Termites). The pairs of wings are of equal size. Swarmers are in search of a mate in search of a new colony.
Once their wings have fallen off a pair will mate, becoming King and Queen. Refer to the Australian Museum Termite Page.
A regular (yearly) termite inspection is recommended for dwellings in termite prone locations. Termite Inspectors use advanced tools like themal imaging-:
When purchasing a new home it is recommended to have a full Building and Pest Inspection. An inspection with 2 experts is recommended. Ideally a builder and a qualified pest control expert.
Termite barriers are an effective termite protection solution -:
Effectiveness - Termite barriers have a high success rate, especially when setup correctly.
Safety - Safely protecting the structural integrity of your home is important. Use a licensed pest control company. Products and chemical used for termite barriers have evolved. Standards ensure only approved products can legally enter Australia. Use products correctly according to manufacturers instructions. Standard labeling makes understanding the products used easier.
Value - The cost of an effective termite barrier is miniscule to the cost of repairing structural damage to your property. A popular product Termidor offers a $2 mil gurantee if the barrier is installed correctly and inspected regularly.
