It is advisable to get the General Disinfestation treatment done at regular intervals as lizards, spiders & crawling insects can always reinfest from the surroundings. The treatment is carried out by spraying insecticide in every crack and crevice of the premises to reach all the hidden parts.
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 room or some other room. They should be covered with an old bed-sheet or newspapers so that the insecticide does not accidentally fall on them.
