Cockroaches are vectors for many diseases such as salmonella, dysentery, gastroenteritis and other gastrointestinal diseases. They mix the food and disperse disease-causing organisms in their stool and secretions.

Life cycle starts with eggs: Cockroaches have only three stages in their life cycle: egg, nymph, and adult. The female deposits its eggs in groups surrounded by a leathery, bean-shaped egg case or capsule called an ootheca. The young cockroaches (or “nymphs”) are wingless and grow in stages by repeatedly shedding the cuticle or skin. They are fully grown after several months to more than a year, depending on the species and other environmental conditions.

Even the cleanest house have a cockroach: Cockroaches and cockroaches eggs can be found everywhere, in food and in packagings. Although sanitation is an important factor in preventing the presence of cockroaches, even the cleanest homes can be invaded due to small amounts of grease, sugar and other foods left over in places difficult to check such as sewers, the rear of fridges and dishwashers or inside the cracks and gaps in the cupboard.

Omnivorous scavengers: Cockroaches are omnivorous scavengers and will consume any organic food source available to them. Although they prefer sweets, meats, and starches, they are also known to consume other items such as cardboard, book bindings, ceiling boards containing starch, their own cast-off skins, dead and crippled cockroaches, fresh and dried blood, excrement, sputum, and the fingernails and toenails of babies and sleeping or sick persons. They even eat each other’s feces. If you see a pepper-like lump in the stove in your kitchen, it may be the stool that cockroaches use to mark the path and nesting grounds nearby.

Nocturnal: Most cockroaches hide in dark, warm and secluded areas by day. They can be found behind furniture and appliances, as well as under refrigerators and stoves and in cupboards or cabinets. They are capable of flattening themselves in order to fit into crevices between floorboards and walls. Roaches are most active at night, during which time they forage for food and mate. If you see cockroaches in the house during the day, you probably have serious problems!

Reproduction: If not controlled, the number of cockroaches entering the home can increase rapidly over several weeks or months and probably become a major risk to health and safety.
