Infestation Definition: what types of infestation are there and what are the signs?
Rats and mice - attack timber, pipes, brickwork, wires. Eat food and can also cause disease, particularly rats (Weil's disease, can be fatal).
Signs - burrowing entrances, droppings, gnaw marks. If in sufficient numbers, can be seen.

Dry and Wet Rot - attack timber and masonry. Can cause severe structural damage. Spores carried in the air.
Signs - both show white fungus and white strands over timbers and masonry. Dry rot can have a distinct odour. Wet rot does not spread as prevalently as dry rot.

Woodworm (Beetles) - various types, including Common Furniture Beetle, House Longhorn Beetle, Death Watch Beetle, Wood Boring Weevil, all attack timber and masonry.
Signs - jagged markings from tunnels bored and dust from the boring (called frass).

Signs - flight holes, appearance of white ant workers and soldiers, noise caused by eating, earthen packing and sometimes odour.

Signs - red/purple shoots in spring, rapidly form canes. Creamy-white flowers in late summer. Leathery dark brown bark of underground rhizome, snaps like a carrot, under bark is orange or yellow.
