Termites are considered devastating economically to humans because of their ability to reproduce millions, over a long period of time. Termites leave trails where they have consumed timber, eating from the inside out, leaving a thin veneer of timber or paint. If walls sound hollow this is a sign there has been termite damage.
Termites construct ‘mud’ tunnels as this provides them with a safe environment to travel or protect their food sources, often located behind your gyprock walls or hidden under the ground.
