Pest infestations of buildings
Household pests can make floors collapse, spread disease, and destroy furnishings.
In the UK, household pests cause millions of pounds of damage each year, with pest control a £100 million industry. Infestations of some sort are common in homes. It is estimated that 25% of homes in the UK have dry rot or wet rot, and that half have woodworm; a further 67 pests are common. These figures are expected to increase with the effects of global warming.
