Roaches are more than just a nuisance. Roaches contaminate surfaces, food and utensils through the indirect transmission of pathogens they carry on their bodies. The remnants of their skins the "exoskeleton" can cause sever allergic reactions in sensitive individuals when it becomes airborne. Prolonged exposure has shown to irritate asthma symptoms as most asthmatics tend to be allergic. Roaches are most prolific in warm humid environments and several species are 'commensal', meaning sharing habitat and food with humans. Nocturnal, they generally hide out of sight in cracks and crevices near food and water sources. Appearance of roaches during the daytime can be a sign of a serious infestation. Roaches are born scavengers and are especially fond of starchy foods such as cereals. They are also known to consume leather, paper, fabric and decaying organic material. Roaches emit a foul odor due to the fluids secreted by scent glands and later regurgitated while eating. Some species of roaches are prolific breeders and very protective of their offspring, so they deposit eggs no more than 24 hours before they hatch.

The best way to prevent roaches is to make sure all entry points on the house are sealed, food is locked and stored away, and to treat it directly by locating the nesting areas. Place screens over vents and pipes that lead inside the house, and check the house on a regular basis for any signs of an infestation. |
