Q. What do you mean by Insect control?
The insects can breed and hide in garbage and other places where there is availability of waste materials. The cockroach lives and breed in moist dark places around plumbing cupboard, pantries and under refrigerators. The best prevention approach is to fit all the doors, windows and ventilation with wire-mesh. The flying insects can be destroyed by employing fluorescent tubes which attract and destroy them due to an electrified field. They are collected in a collecting tray. The crawling insect hideout should be sealed by blocking all the cracks etc. which harbor insects. They are generally destroyed by spraying and using commercial insecticides like pyrethrum. The cockroaches can be prevented entry by painting a band of insecticide between the joints of wall and floor. Of late, aerosol sprays have become very popular in eliminating flying insects. But care has to be taken to avoid contamination of foods and food contact surfaces getting sprayed with the aerosols.
