Dry Rot Treatment
The True Dry Rot Fungus (Serpula lacrymans) is a brown rot that gets its common name from the condition it leaves the wood in after it has consumed all the cellulose. The wood is light, brittle and easily crumbles while showing the characteristic cuboidal cracking.
It is the only brown rot with the ability to extend out from the initial point of germination. Using fine hyphae, mycelium and risomorphs it is able to travel through masonry and behind plaster. Therefore, expert identification and eradication is essential. 
Wet Rot Treatment
This common term for decay in wood covers hundreds of fungi that break down either the cellulose or the lignum in wood. They are distinct from the True Dry Rot Fungus as generally the attack is restricted to the timber that is getting wet.
The viscous species can be hard wood or soft-wood specific. A classical attack is the breakdown of a beam end built into a solid wall.  Quite often, there is insect attack such as Euophrym confine (Wood Boring Weevil) and Xestobium rufovillosum (Death Watch Beetle). Remedial action is quite straight foward. Isolate or remove the moisture source and replace the defective timber.
Wood Worm Treatment
Wood boring insects together with wood rotting fungi are two important agents in the break down of dead organic material. Their role is to return the nutrients to the ground. This is good except that we use timber in our properties, so these insects follow their food source into our homes.
They are introduced in various ways:
1. Built into the building already carrying an infection. A classic example is Death Watch Beetle (Xestobium rufovillosum).
2. Brought into the house in infested furniture.
3. Brought into the house by twigs carried by birds.
4. Fly into the house as an adult.
Eradication varies according to the insect concerned but generally, control is achieved by the use of insecticides.
