Facts about roaches
Did you know that roaches are one of the oldest living creatures that inhabited our planet from its earliest time just like the dinosaurs? Throughout the Earth’s history these insects have managed to adapt to adverse living conditions to such an extent that their extermination is not an easy task at all.
Cockroaches belong to the insect order Dictyoptera. Young and immature cockroaches resemble adults, that is, they undergo gradual metamorphosis. Adults of male species have wings although many species do not fly. There are 70 described species of cockroaches in the United States, and over 3,500 worldwide, but only a few are major pests.
Diseases spread by cockroaches
Cockroaches are persistent and troublesome pests in homes, restaurants, hospitals, warehouses, offices, and other tall structures with food-storage areas. These insects contaminate food and kitchenware we use for food handling and cooking. Moreover, they can destroy or stain fabric, paper products and other surfaces they come in contact with.
Cockroaches are universally loathed. Everyone is disgusted at the sight of them. They can appear in any place where there is biological waste such as sewers, septic tanks, garbage cans, chicken houses and animal cages.
Their attraction to human and animal feces, rotting food, secretions from corpses, sputum, pus, and the like, makes them very dangerous reservoirs of bacteria and other microorganisms. This is so because all these moist, organic habitats contain staggering amounts of bacteria, protozoans, amoebae, fungi, and other microbial material.
Example of such roaches that come in contact with feces are German cockroaches. They may easily transmit bacteria responsible for food poisoning. They act as mechanical vector in transmitting Salmonella, Shigella and Cryptosporidium parvum – bacteria that cause diarrheal diseases.
Antibiotic resistant strain of Klebsiella pneumoniae bacterium (transmitted by cockroaches) that causes pneumonia has been found in diseased patients in a New Delhi hospital. In addition, evidence suggests that cockroaches spread typhoid, dysentery and leprosy organisms.
Now, who wants cockroaches around their house? I know I don’t. And it can be a rather difficult job to get them out of the house once they get in.
Do not let these gross little critters roam around your home when there is little something you can do to deal with them.
Here’s what you can easily and readily do:
Take a cucumber, cut it into pieces or slice it, then put it in the corners where you have noticed the movement of cockroaches. The smell of this vegetable will serve as a natural barrier to keep the roaches away.
However, if the problem with these critters persists, you need to buy a more powerful insecticide or pesticide.
