Cockroaches (or simply “roaches”) are insects of the order Blattaria. This name derives from the Latin name for the insect, Blatta.
There are about 4,000 species of cockroach, of which 30 species are associated with human habitations and about four species are well known as pests. Among the best-knon pest species are the American Cockroach, German Cockroach & Brown-Banded Cockroach.
Cockroaches are one of the most commonly noted household pest insects. They feed on human and pet food, and can leave an offensive odor. They can also passively transport microbes on their body surfaces including those that are potentially dangerous to humans, particularly in environments such as hospitals. Cockroaches have been shown to be linked with allergic reactions in humans. One of the proteins that triggers allergic reactions has been identified as tropomyosin. These allergens have also been found to be linked with asthma.
General preventive measures against household pests include keeping all food stored away in sealed containers, using garbage cans with a tight lid, frequent cleaning in the kitchen, and regular vacuuming. Any water leaks, such as dripping taps, should also be repaired. It is also helpful to seal off any entry points, such as holes around baseboards, in between kitchen cabinets, pipes, doors, and windows with some steel wool or copper mesh and some cement, putty or silicone caulk and routine pest control service.
