Wood Destroying Beetles
There are many species of wood boring beetles that attack wood and cause massive devastation to wood floors, furniture, beams and other wooden structures. The beetles lay their eggs into gaps in the wood which will hatch larvae who burrow deep into the wood creating a maze of tunnels weakening the woods integrity. This will eventually lead to total failure of the structure.
- Holes in wood and timber - The larvae will eventually bore to the surface of the wood to pupate and come up in their adult form. This will leave a clean looking round or oval hole. They may also tunnel sideways near the surface of the wood which will eventually leave a small trench or furrow.
- Dust - Dust expelled from tunneling will usually collect under the infested wood.
- Feeble floorboards - After years of infestation the wood will become soft and weaken considerably. This will lead to crumbling and disintegration.
- Beetle larvae - white coloured larvae which look like worms.

Wood destroying Organisms - Fungi
Wood destroying fungus cause irreparable damage to your home or business. Fungus causes more damage to wooden structures than the damage caused by termites, fire and floods combined. Fungus can occur when the moisture level of the wood exceeds 20% and a temperature between 0 and 32 degrees celsius.
There are four types of wood destroying fungi:
- Water-conducting fungi: These fungi do not need a water leak to grow as it uses root like tubes that conduct water. Even wood protected from water leaks can be infected. Once this fungus has taken hold it can quickly destroy wooden structures, floors, walls and ceilings.
- Brown rot fungi: Wood infested with brown rot fungi will dry, shrink and become discoloured. Over time the wood becomes fragile, can crack and when crushed will turn to powder. The structural integrity of the wood can be severely weakened even before evidence of the destruction can be seen.
- White rot fungi: Wood infected with white rot fungi will become wet, soft and sponge-like. Wood will appear white as if it has been bleached. The wood will shrink and become spongy and eventually collapse if under load.
- Soft rot fungi: Soft rot fungi requires high moisture and nitrogen levels which makes it most commonly found infecting window frames, wet floors and wood close to the ground like fence posts.
