Government Buildings The MAFF and the DAFS are jointly responsible for the control of pests including insects and mites in Crown properties in Great Britain and provide a service for this purpose. The type and number of insect infestations occurring in Government buildings reported in one year to the MAFF regional pests organisation in the London area are given in Table 12. The number of treatments carried out at airports and at buffer depots (which contain Government stocks of home-milled flour and other com- modities) are also given individually in parentheses. About 40 per cent of the treatments were in premises storing food. The total quantity of all insecticides used by the MAFF and the DAFS in Government buildings and airports during a twelve month period is given in Table 13. Insecticides used in prisons and borstal institutes is proportionally high compared with Government buildings as a whole and is therefore presented separately. Dieldrin was invariably used for cockroach control principally in the form of a lacquer in kitchens and food stores. It was also used as a dust in heating ducts, air vents, cavity walls, and boiler rooms, which often serve as centres of infestation. Chlordane was used against ants, often outside buildings, and to a lesser extent to control cockroaches. DDT was used primarily against flies. Table 12.
