Spraying in pest/vector control, the typical standard of applying pest-control chemicals and other compounds. In spraying, the chemicals to be applied are dissolved or suspended in water or, less commonly, in an oil-based carrier.
APC conducted Cockroach misting using water based preparation. Misting is effective in dealing numerous pests which include cockroaches. It leaves a residual on plants, animals, soils, shrubs and building structures which are fatal to the cockroach when in contact. Misting will penetrate fully because of its small particle size of about 25 mircon. Misting solution is of low toxicity and will not pose any health hazard to people working in the job site. Misting unlike fogging, does not emit smoke and is environmental friendly.
Cockroach bait gels are applied to areas frequented by cockroaches such as between different elements of construction, between equipment and floors, openings leading into voids and hollow spaces in floors, walls, ceilings, equipment legs and bases, around plumbing pipes, doors and windows, and behind and under appliances, cabinets, sinks, closets, and any other equipment that cockroaches are typically known to hide.
Generally, insecticides in dust formulation are applied to areas where pests are known to hide and migrate - especially areas where insecticide sprays do not reach or cannot be safely applied. When used correctly, dusts will give a much longer pest killing residual than liquids.
