Cockroaches are a high-risk pest to have in your premise. They carry a range of serious illnesses, including salmonella food poisoning, dysentery, diphtheria, gastroenteritis, and typhoid. Furthermore, cockroaches have been identified as a major source of powerful allergens, often the cause of asthma, allergies, and eczema, especially in urban areas. The health risk is particularly high in homes with children, the elderly or those fighting illnesses.
Beyond the health risks, cockroaches are a distasteful pest to have in your premise. They are not only a disturbing sight, they cause contamination and can produce an obnoxious odour that taints food and objects which they come in contact with. If the conditions are good, and temperatures sufficient, as is the case all around the year in most parts of India, cockroaches can breed rapidly. They are highly resilient and have developed resistance to a number of insecticides. A quick response is therefore essential to ensure that cockroach infestations do not go out of control or spread to neighbouring properties.
Right at the back of bathroom cabinets (especially if they are full of soaps and toiletry products that have been stored for a while) or medicine cabinets.
look in cupboards and cabinets, pay attention to hidden areas with pipework such as under sinks and behind dishwashers.
Cupboards under sinks, where plumbing enters through walls or floors leading to washing machines and tumble dryers. Also check warm areas near the motors at the back of washers and dryers.
Look around down pipes for cracks and crevices they might hide in, as well as damaged drain covers they could scuttle through. Other areas to check are pipe ducts and any opening beneath porches or decking.
An established cockroach infestation produces a lingering and unpleasant odor that taints items they contact.
If little water is available cockroaches will produce brown/black cylindrical droppings, approx. 2mm long.
If water is abundant cockroaches will produce brown and irregular shaped smear marks. Check for marks on horizontal surfaces and at wall-floor
Cockroaches shed 'cast nymphalid' skins 5-8 times as they mature to adults. These shed skins are usually found close to where the cockroaches are sheltering.
Because they are drawn to human food, cockroaches are a cause of food contamination. Some of the dangers of cockroaches in this regard include bacterial infections. The Salmonella bacteria can also be spread by cockroaches, where it can cause diseases ranging from food poisoning to typhoid.
Another disturbing, though unlikely, health risk of cockroaches in close contact with humans is that of entering body cavities. Young cockroaches have been reported to crawl over sleeping humans and crawl inside of ears, nostrils, and open mouths.
Another health risk of cockroaches is allergic reactions. Cockroaches are one of the most common allergens reported, with studies finding anywhere from 20 to 60 percent of urban residents presenting with cockroach allergies. These symptoms can range from itching and redness to severe asthma.
