All utensils, containers, raw and cooked food should be removed from the kitchen (or from the area for making tea etc. in offices) and kept on the dining table or in the middle of the drawing or some other room. They should be covered with an old bedsheet or newspapers so that the insecticide does not accidentally fall on them.
The insecticide reacts with plastic and silver. Hence all plastic and silver articles should be kept away under cover. Please cover all the plastic articles such as TV, Computers, Audio Systems, Telephone Instruments etc.
