Many people hate cockroaches, especially in the technology developed in a civilized society.That they are not clean and affect our health.Now, let us briefly look at the ecology of cockroaches.

Role as Pests

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 tight lids, 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, between kitchen cabinets, pipes, doors, and windows with some steel wool or copper mesh and some cement, putty or silicone caulk.

Diatomaceous earth applied as a fine powder works very well to eliminate cockroaches as long as it remains in place and dry.[citation needed] Diatomaceous earth is harmless to humans and feels like talcum powder. Most insects, including bed bugs, are vulnerable to it.

Some cockroaches have been known to live up to three months without food and a month without water. Frequently living outdoors, although preferring warm climates and considered "cold intolerant", they are resilient enough to survive occasional freezing temperatures. This makes them difficult to eradicate once they have infested an area.

Of the numerous parasites and predators of cockroaches, few have proven to be highly effective for biological control of pest species. Wasps in the family Evaniidae are perhaps the most effective insect predators, as they attack the egg cases, and wasps in the family Ampulicidae are predators on adult and nymphal cockroaches (e.g., Ampulex compressa)[citation needed]. The house centipede is probably the most effective control agent of cockroaches,[citation needed] though many homeowners find the centipedes themselves objectionable.

Ampulex wasps sting the roach more than once and in a specific way. The first sting is directed at nerve ganglia in the cockroach's thorax, temporarily paralyzing the victim for two to five minutes, which is more than enough time for the wasp to deliver a second sting. The second sting is directed into a region of the cockroach's brain that controls the escape reflex, among other things. When the cockroach has recovered from the first sting, it makes no attempt to flee. The wasp clips the antennae with its mandibles and drinks some of the hemolymph before walking backwards and dragging the roach by its clipped antennae to a burrow, where an egg will be laid on it. The wasp larva feeds on the subdued, living cockroach.

Bait stations, gels containing hydramethylnon or fipronil, and boric acid powder are toxic to cockroaches. Baits with egg killers are also quite effective at reducing the cockroach population. Additionally, pest control products containing deltamethrin or pyrethrin are very effective.

In Singapore and Malaysia, taxi drivers use pandan leaves as a cockroach repellent in their vehicles.

An inexpensive roach trap can easily be made from a deep, smooth-walled jar with some roach food inside, placed with the top of the jar touching a wall or with sticks (outside the jar) leading up to the top, so the roaches can reach the opening. Once inside, they cannot climb back out. An inch or so of water or stale beer (by itself a roach attractant) will ensure they drown. The method works well with the American cockroach, but less so with the German cockroach. A bit of Vaseline can be smeared on the inside of the jar to enhance slipperiness. The method is sometimes called the "Vegas roach trap" after it was popularized by a Las Vegas-based TV station. This version of the trap uses coffee grounds and water.

Use of Cockroach

Some of the earliest writings about cockroaches encouraged their use as medicine. Pedanius Dioscorides (first century), Abu Hanifa ad-Dainuri (9th century), and Kamal al-Din al-Damiri (14th century ) all offered medicines that either suggest grinding them up with oil or boiling them, and Lafcadio Hearn claimed, in the 1870s, many New Orleanians had great faith in a remedy of boiled cockroach tea.

Cockroach Dishes

If a cockroach in your dishes while you are enjoying the lunch in a restaurant, what will you do?

I believe that no one will be very calm. However, there are some dishes making from cockroach.

Flies, cockroaches, pickled bees and lunch!

Legal disclaimer: If you are prone to squeamishness I suggest putting down your chai tea latte and raspberry muffin! This is going to get ugly!

Although I have an adventurous spirit my wanderlust seems to abandon me when it comes to what I put in my mouth! I am not the type of traveler who revels in eating fried cockroaches on the streets of Thailand, pickled bees in Mongolia or the crispy locusts on offer in Vietnam. I am way too boring for that! There is something about my fear of getting violently sick that has kept me from venturing too far from the staples of western food. But read on and you will soon see that even the most intricate ‘self preservation eating techniques’ don’t pan out too well when you travel off the beaten path…

I found my way into an Urt (a traditional Mongolian tent) in the middle of the Gobi desert and it was here that I was given an innocuous looking cup of fresh camel milk. Sounds good so far. It won’t for long! There were 4 flies in my milk. 3 dead. 1 dying. It would have been exceedingly rude to refuse my host’s gift of fresh camel milk, so I took a sip! On the best of days I don’t suggest drinking camel milk. I certainly don’t suggest drinking camel milk infused with Mongolian flies…

On another occasion whilst traveling through India I had the misfortune of eating ‘Rice ‘ala’ ant.’ Yes, my rice dish was infested with dead ants. A whole family of ants massacred and placed in my food… Now I know what you are thinking: How the hell did the chef miss this? (If you had seen the state of the kitchen, and the state of the ‘chef,’ you would understand) It goes without saying that I did not finish my meal. In fact I didn’t even start it.

The funny thing about this story was that the restaurant was the only one in the village and I stayed in that village for one week! Each night I was forced to go back, in order to ‘sustain life,’ and my friends ‘the ants’ were waiting for me in my food. Sometimes alive. Sometimes dead. By day three I was forced to eat. And yes, I probably inadvertently ate some ants… To this day every time I get a rice dish I rummage around for signs of life.

But wait, there is more, and it gets worse! I was on a container ship traveling through the Panama Canal on my way to Puerto Bolivar in Ecuador and the Captain insisted I eat at his table. This was good. Or so I thought. The salad that he brought out had two cockroaches in it. One dead. One very much alive. I decided against eating that night. In fact I feigned illness and went to my room. For the rest of the trip!

I learned valuable lessons after my close encounters with the flies, the cockroaches and the ants. If you want to stay safe, go to McDonald’s. If you want to have an adventure, travel the world and you may get to eat some flies, but at least you will have a story to tell…

Cockroach in Museum

Houston Museum of Natural History Wants to Buy Your Roach

Amateur entomologists may finally have a financial incentive for keeping their creepy little friends around, or in this case, trading them in. The Houston Museum of Natural History is offering cold hard Cash for Cockroaches with the goal of collecting 1,000 of our twitchy little house mates for the New Brown Hall of Entomology. Admittedly, 25 cents a pop may not be enough to lure one away from a career in investment banking, but hey, all we usually get for spotting a cockroach is a chance to wipe our shoes.

Houstonians are invited to contribute their cockroaches at the entrance to the Cockrell Butterfly Center on Tuesdays (May 8th and May 15th) from 4 – 7 p.m. or Saturdays (May 5th, May 12th and May 19th) from 12 – 3 p.m. for $0.25 each. Upon arrival, ask for a Museum entomologist. After the first 1,000 cockroaches are collected, donors will be given passes to come back and visit their friends when the new Brown Hall of Entomology opens May 25, 2007.

Cultural References

Because of their long, persistent association with humans, cockroaches are frequently referred to in art, literature, folk tales and theater and film and real life. In Western culture, cockroaches are often depicted as vile and dirty pests. Their size, long antennae, shiny appearance and spiny legs make them disgusting to many humans, sometimes even to the point of phobic responses. This is borne out in many depictions of cockroaches, from political versions of the song La Cucaracha where political opponents are compared to cockroaches, through the 1982 movie Creepshow and TV shows such as the X-Files, to the Hutu extremists' reference to the Tutsi minority as cockroaches during the Rwandan Genocide in 1994 and the controversial cartoons published in the "Iran weekly magazine" in 2006 which implied a comparison between Iranian Azeris and cockroaches. The second part of the Harry Hole crime novels written by Jo Nesbø is called The Cockroaches (Kakerlakkene in Norwegian). In the movie Men in Black a giant alien cockroach is shown as a predator who eats a farmer and then uses his skin to disguise itself as a human being. In Oliver Twist, the children, Mr. Bumble, and Widow Corney sing about feeding Oliver cockroaches in a canister. Award-winning computer and video game series Fallout takes place in a postatomic bomb war universe, in which enlarged, irradiated cockroaches are present as early enemies. This is a nod to the notion of their nuclear fortitude. Also, in Franz Kafka's The Metamorphosis, a man, Gregor, is transformed overnight into a monstrous insect with cockroach-like features. He views himself as repulsive in his new identity. Ayn Rand in her early novel "We the Living" compared the Soviet Union to a huge pile of cockroaches. During Australian Rugby League State of Origin matches, it is common slang to refer to Queensland as canetoads and New South Wales as cockroaches.

Not all depictions of cockroaches are purely negative, however. Twilight of the Cockroaches depicts the extermination of cockroaches as a holocaust, and presents a happy ending as the pregnant lead cockroach, Naomi, escapes to mother many generations. In the Pixar film Wall-E, a cockroach that has survived all humanity is the best friend of the lead character (a robot), and waits patiently on him to return. The same cockroach survives getting squished twice. In the film Joe's Apartment, the cockroaches help the titular hero, and the narrator of the book archy and mehitabel is a sympathetic cockroach. In the book Revolt of the Cockroach People, an autobiographical novel by Oscar Zeta Acosta, cockroaches are used as a metaphor for oppressed and downtrodden minorities in US society in the 1960s and 70s. The image of cockroaches as resilient also leads people to compare themselves to cockroaches. Madonna has famously quoted, "I am a survivor. I am like a cockroach, you just can't get rid of me." "Cockroach", or some variant of it is also used as a nickname, for example Boxing coach Freddie Roach, who was nicknamed La Cucaracha (The Cockroach) when he was still competing as a fighter. The album The Lonesome Crowded West by rock group Modest Mouse features a song with the title and lyric "Doin' The Cockroach". In the Netherlands 'Zaza the cockroach' becomes a buddy of the boy called Pluk in a popular Dutch book for children, Pluk van de Petteflet, written by Annie M.G. Schmidt. In Suzanne Collins's Underland Chronicles series, giant cockroaches are allies of humans in the Underland, and they and a toddler named Margaret (a.k.a. Boots, or "the princess," as the cockroaches call her) love each other.
