Cockroaches' Weird Grooming Behavior Explained

19 Mar 2013

Posted by Joseph Coupal

Perhaps Fluffy the cat let roaches and other insects in on a little secret about cleanliness: Turns out, the creepy crawlies incessantly groom themselves to keep their antennae free from environmental pollutants and chemicals the insects themselves produce, a new study shows.

The catlike bathing removes debris in order to keep insects' sense of smell sharp for finding food and mates and sensing danger, the researchers report today (Feb. 4) in the journal Proceedings of the National Academy of Sciences..

"The evidence is strong: Grooming is necessary to keep these foreign and native substances at a particular level," said study co-author Coby Schal, an entomologist at North Carolina State University, in a statement. "Leaving antennae dirty essentially blinds insects to their environment.".

Though animals from mammals to insects are known to groom themselves, exactly why insects such as cockroaches do so remained a mystery..

To investigate the phenomenon, Schal and his colleagues compared the antennae of cleaned American cockroaches with those on cockroaches prevented from grooming. Normally, the bugs use their forelegs to shove their antennae into their mouths, and then systematically lick from top to bottom.

In the experiment, when antennae got dirty, they accumulated both environmental chemicals and a waxy substance that the giant insects secrete to stay hydrated.

By contrast, when insects were able to clean themselves, the action uncovered tiny pores on the antennae that allow sensory chemicals to travel to olfactory nerves, letting the cockroaches smell key chemical signals..

When the researchers exposed both groups of cockroaches to sex pheromones, or chemicals used by the insects to communicate about mating, scientists found the clean antennae could better detect the mating chemical than could dirty ones..

The team then subjected carpenter ants, German cockroaches and houseflies to similar experiments and found that all of the insects' antennae accumulated debris that could impair their senses of smell. (Carpenter ants rub their legs over their antennae to clean the organs.).

The findings could help in the design of better insecticides against the creepy crawlies. Many existing insecticides must slowly seep through insects' waxy outer cuticles. But because cockroaches constantly lick their antennae, a mist that settles onto these organs could cause the bugs to eat the poison very quickly, the researchers suggest..

Weird News: Man Dies After Live Cockroach, Cricket, Worm Eating Contest

11 Jan 2013

Posted by Joseph Coupal

As a Florida medical examiner tries to determine how 32-year-old Edward Archbold died after eating insects during a contest to win a snake, people around the country are asking: Why?

Why would anyone eat a live cockroach? Why did he die when several others in the contest ate the same bugs without incident? What inspired Archbold – who was described by the snake store owner as “the life of the party” – to shovel handfuls of crickets, worms and cockroaches into his mouth?

While eating bugs is normal in many parts of the world, the practice is taboo in the U.S. and many Western countries.

Yet people do it for the shock factor, and many do so during contests or dares; just last year, folks ate Madagascar cockroaches at a Six Flags in Illinois for a chance to win park passes. Also last year, people ate live roaches at the Exploreum Science Center in Mobile, Ala. And a few years back, at Universal Studios in Orlando, contestants in a theme park show purportedly consumed a mix of sour milk, mystery meat and bugs.

Experts point to the rise in reality TV shows and movies such as “Fear Factor” and “Jackass” as egging people on and breaking down the ick factor.

Competitive eaters – like the participants who scarf down hot dogs on Coney Island on the Fourth of July – are quick to distance themselves from stunts like cockroach eating. Competitive eating is regulated, has rules and always has a licensed emergency medical technician on hand at every event.

Lou Manza, a psychology professor at Lebanon Valley College, said folks who participate in extreme events like bug eating “are looking for things to make life interesting.”

“At a certain level we’re all looking for things to break up the monotony,” said Manza, who participates in extreme marathons, which he says some people think is odd. “We’re striving for something that gives life meaning, something beyond the ordinary. The older you get, you start looking for something else.”

Extreme eaters also participate mostly for fame and not material goods – and they train heavily for events. Manza added that amateurs don’t “think things through” when throwing themselves into weird and possibly dangerous competitions.

Case in point: In 2007, a 28-year-old mother of three died after participating in a California radio station contest called “Hold Your Wee for a Wii,” where she tried to drink large quantities of water without urinating in order to win a gaming console. Overconsumption of water throws the body’s electrolyte balance out of whack and can be fatal.

What made Archbold participate in the bug-eating contest is a bit unclear; he had eaten bugs before, said his girlfriend. He had planned on giving the female python to a friend if he won.

Natasha Proffitt, 27, of West Palm Beach, said Archbold told her about the contest just hours before it started on Friday. When she asked him if it was a good idea, he said “it was not a big deal.”

The store, Ben Siegel Reptiles in Deerfield Beach, had been touting the contest for days on its popular Facebook page; earlier on Friday it posted a flyer that said the event was “featuring the soon to be infamous ‘eat bugs for balls’ contest,” referring to the prize of a female ivory ball python.

Sarah Bernard, an entomology student at the University of Florida, attended the contest – held during the store’s “Midnight Madness Sale” – and shot video on her phone of Archbold during the competition.

“I was focusing on him because I was closest to him and he was really entertaining,” she said of Archbold. “I saw that he had a clear strategy. He would push everything into his mouth and try to swallow it with water. He figured out what worked, and he did it.”

She added that the participants competed in several different rounds with different insects, and that the last contest involved the roaches, which were three or four inches long.

“The worm contest happened right before the roach-eating contest. So he ate a very large number of insects,” she said, adding that each round lasted about four minutes.

Archbold won the contest.

Bernard said she did not see Archbold immediately after the competition ended. She recalled that an announcer said “the winner was vomiting somewhere, and we’ll congratulate him when he comes back.”

Archbold, of West Palm Beach, collapsed in front of the store, according to a Broward Sheriff’s Office statement released Monday. He was taken to the hospital where he was pronounced dead. Authorities were awaiting autopsy results to determine a cause of death.

The medical examiner’s office said Tuesday it has sent samples of Archbold’s remains for testing, but results are not expected for another week or two.

“Eating insects in a contest is a recent ‘Fear Factor’ phenomenon,” said Coby Schal, a professor of entomology at North Carolina State University. “But I have not heard of anyone having that type of response.”

He said people may have allergic and asthmatic responses to cockroaches, particularly in homes infested with roaches, and children are very seriously allergic to them. Dust from roaches’ wings and exoskeletons – roaches shed their skins – often triggers asthma in people.

“All insects, if you are allergic to a particular insect, you can have an allergic response to it. Whether he had an allergic sensitivity to a wide variety of insects or just to roaches, there is no way of telling,” Schal said.

Schal said this was likely an allergic response, “but there is always a possibility that cockroaches do carry bacteria and the response won’t be immediate. It would take time for bacteria to be a problem.”

He added that there could be other complications.

“When cockroaches like this die or are sick, they can have bacterial infections,” Schal said. “But the fact that he was the only one affected, it suggests that it’s something about his physiology.”

Mike Tringale, the vice president of The Asthma and Allergy Foundation of America, said it’s possible that Archbold “hit his tolerance level to cockroach allergens” and went into anaphylactic shock.

Tringale said that such a severe reaction to cockroaches is “probably rare,” however.

David George Gordon has made a career out of educating people about edible bugs. His many books include the “Eat-a-Bug Cookbook,” which features a recipe for cockroach samosas. And though he has hosted his own cockroach-eating contests, he is dismayed by events and reality television programs that focus more on the gross-out factor than on showing people the culinary side of insects.

“It’s indirectly bashing other cultures,” Gordon — who goes by the Twitter handle TheBugChef — said in a telephone interview. “We kind of like to think all these other cultures are so suffering from lack of nutrition that they eat bugs. Which is kind of like saying we eat oysters on the half shell because we need protein. This is not about nutrition. This is legitimate comfort food in many parts of the world.”

The Truth about Cockroaches and Health

09 Jan 2013

Posted by Joseph Coupal

Cockroaches live in a wide range of environments around the world. These pest species prefer warm conditions and thus are commonly found in the buildings of densely populated cities and also in the southern United States. In fact, the Asthma and Allergy Foundation of America reports that 78 to 98 percent of urban homes have cockroaches – with as many as 900 to 330,000 cockroaches per home!

Cockroaches are most active when the temperature is greater than 70 degrees Fahrenheit and they thrive in warm environments with easily accessible food and water. These insects are mainly nocturnal and will run away when exposed to light. Amazingly, some cockroaches have been known to live up to three months without food and a month without water.

Cockroaches have many negative consequences for human health because certain proteins (called allergens) found in cockroach feces, saliva and body parts can cause allergic reactions or trigger asthma symptoms, especially in children.

Cockroach allergy was first reported in 1943, when it was noted that certain patients developed skin rashes immediately after the insects crawled over their skin. Allergy skin tests were developed in 1959, which confirmed patients’ cockroach allergies. Subsequent studies have firmly established that cockroach allergens can act as a trigger for acute asthma attacks.

The National Cooperative Inner-City Asthma Study (NCICAS) found that asthmatic children with both a positive skin prick test to cockroach allergen, and a high exposure to cockroach allergen in the bedroom were more likely to have wheezing, missed school days, nights without sleep, and unscheduled medical visits and hospitalizations for asthma. Approximately 23 percent to 60 percent of urban residents with asthma are sensitive to the cockroach allergens. However, the risk of asthma from cockroach allergen exposure and allergy is not limited to children. The study also found that cockroach allergy was associated with more severe asthma among elderly asthmatics in New York City.

Asthma is a serious, sometimes life-threatening chronic respiratory disease. Unfortunately, it directly affects the quality of life for almost 25 million Americans, including an estimated 7 million children. Millions more are impacted as family members of persons with asthma. Although there is no cure for asthma, it can be controlled through medical treatment and management of environmental triggers – such as cockroach allergens.

Cockroaches can also passively transport microbes on their body surfaces including pathogens that are potentially dangerous to humans. Cockroaches have been implicated in the spread 33 kinds of bacteria, including E. coli and Salmonella species, six parasitic worms and more than seven other types of human pathogens.

E. coli and Salmonella are classic causes of food poisoning, or gastroenteritis. Common symptoms include belly pain, severe stomach cramps and tenderness, diarrhea which can sometimes be bloody, nausea and vomiting. Some people can experience severe diarrhea, which will cause dehydration and may require hospitalization. In rare cases, the bacteria can spread to the blood stream and cause life threatening infections.

People can mitigate cockroach problems and protect their health through barrier exclusion and cleanliness. Barrier exclusion involves preventing cockroaches from entering the home through places, such as small cracks in the walls and spaces near electric sockets, and up through drain traps. Having a clean and sanitary home will make it less inviting to cockroaches.

Five things to do to protect your home and family:

  1. Keep counters, sinks, tables and floors clean and free of clutter. Clean dishes, crumbs and spills right away.
  2. Store food in airtight containers, and always avoid leaving food out (including pet food!).
  3. Seal cracks and gaps in walls, floors and openings around or inside cabinets. Condo- and apartment-dwellers should also seal gaps around plumbing, wall outlets, and switch plates.
  4. Run water periodically in spare bathrooms and little used sinks.
  5. Scan children’s backpacks when they return home, as well as grocery items before storing them.

Ultrasonic Roaches!!!

27 Nov 2012

Posted by Joseph Coupal

So you bought an electronic pest repeller for $9.99 and plug it into an outlet and it repels all insects from your entire house. That’s how it works right? I mean if it were that good there would be no pest control industry! These gimmick devices have been soundly disproven by science again and again. The problem is that people do not believe science and facts so millions of these stupid things are still being sold every year!

Well, here is some visual proof that proves yet again that these things are a gimmick. This ultrasonic unit was plugged into an outlet in an apartment in Boston. As you can see it did absolutely nothing to repel or control the German Cockroaches. In fact they seemed to love the extra warmth it provided as evident by the copious amounts of fecal matter. Perhaps I should go into the snake oil sales business?

American Cockroaches (Americana blatanica)

16 Nov 2012

Posted by Joseph Coupal

We saw some big roaches in the basement... ya think! The good old American Cockroach (Americana blatanica) and he is VERY common in major cities. The older the building the better chance you have of seeing this guy. The are BIG roaches! Many people call them the water bug or palmetto bug.

(click image to enlarge)

Despite their pronounced wings they are not great flyers, they sort of flutter for short distances. They inundate city sewer, septic, steam, etc. pipes and get into buildings this way. In really urban sections they walk the streets on hot and humid days having come out of the underground street pipes. You can treat and suppress their activity but the real solution in those inaccessible pipes.

American Cockroaches

07 Nov 2012

Posted by Joseph Coupal

Every visit = dozens upon dozens of American Cockroaches being caught on our insect monitors. Dozens more seen alive in the basement and boiler room. Tenants in the lower level floors were seeing them in their apartments. Treatment was suppression not elimination of the issue. It was like a band aid on a bullet wound! We told the property management firm that we must find the source! We said with absolute confidence that it was under the slab. Sure enough the slab was jack-hammered and PVC pipes were found broken and uncapped. In fact these pipes need to be lead not plastic! These were pipes leading to the water system of the city so roaches had a direct run from the city water system in the streets directly into the apartment building!

(click image to enlarge)

The pipes were fixed and the roach issue was solved! TRUST the expert advice that EHS offers and a solution will follow!

EHS Gives back To The Community

02 Nov 2012

Posted by Joseph Coupal

EHS Pest's Sabrina Key and George Williams doing their part for the Boys and Girls Club of Boston!

A Helping Hand

Volunteers from NPMA’s Leadership Development Group volunteered time and effort at the Boys and Girls Club of Boston, just prior to PestWorld.

BOSTON — The Boys and Girls Club of Boston is looking refreshed, and its children left with a few buggy lessons and possibly new role models after the NPMA’s Leadership Development Group (LDG) volunteered its time there before PestWorld 2012 officially kicked off, earlier this month.

“The LDG decided collectively to make an effort to give back to the communities we travel to,” said Jen Marlowe, committee chair for LDG, adding that this idea came to a head several years ago during one NPMA Academy. Marlowe credited past LDG chairs Justin McCauley and Adam Witt in helping kick-start the initiative. At PestWorld 2011 in New Orleans, LDG assisted the local Habitat for Humanity chapter.

In Boston, Marlowe said the volunteer group was on site for over three hours, where they first helped with site maintenance needs – that included painting, picking up trash, raking leaves and weeding.

After, the group worked and interacted with about 60 kids under the age of ten. “We started with a presentation on ‘good bugs’ versus ‘bad bugs” and stressed the importance of using a professional,” Marlowe said. The group showed the children some “artifacts” from the field, including a wasp nest and containers damaged by chewing from rodents.

And of course, the kids got to get their hands on everyone’s favorite pest: the Madagascar Hissing Cockroach.

“Sometimes it’s hard to know the impact you make when trying to do good for others,” Marlowe said. “But luckily for us, the kids made this day very rewarding by wearing their enthusiasm, creativity and gratitude on their sleeves.

“We decided that this mission to give back will hopefully inspire other members of our industry to get involved in our efforts, or efforts within their own communities,” Marlowe continued. “But we also wanted people outside our industry to feel the need to pay it forward.”

Lady GaGa Designs Live Cockroach Hat?!

22 Aug 2012

Lady Gaga Designs Mad Live Cockroach Hat

The singer has instructed her designers to come up with a hat filled with cockroaches.

She’s grown fond of the insects since being informed of a study which proved they respond to her music more than songs by any other artist.

A source said: “Lady Gaga has been looking to top her famous meat dress for some time — and this could be it.

“She dubbed cockroaches ‘My real life monsters’ after hearing of the recent study.

“Now she wants to incorporate them in a headpiece by having them crawling around inside a netted cage.”

Last year students in New York, who were studying the engineering and movements of cockroaches, played music to the insects to get them moving after they failed to respond to electric pulses.

After material from Weezer and heavy metal group Avenged Sevenfold bombed, Gaga’s hits sparked them into life.

At least this headwear will be one of the cheapest in her massive collection.

A box of cockroaches shouldn’t set her designers back too much at her local pet shop.

Wearing the creepy crawly-filled hat is also handy preparation should her career nose-dive and she ends up in a future series of I’m A Celebrity . . . Get Me Out Of Here. I’d love to see her in the jungle alongside Michael Owen, Stavros Flatley and Lindsay Lohan.

Meanwhile, Gaga suffered concussion on stage in New Zealand after a dancer cracked her over the head with a pole.

She didn’t let the accident cut short her sell-out show though, and completed 16 more songs.

She told her audience: “I want to apologise. I did hit my head and I think I may have a concussion but don’t you worry, I will finish this show.”

The dancer must have seen a cockroach.

Why Roaches Need Their Friends

18 Jul 2012

Posted by Joseph Coupal

Why Cockroaches Need their Friends

The much maligned cockroach is more sophisticated, and social, than we thought, according to new research.

They hide away, unseen, lurking in dark corners and crevices.

When they emerge, they aimlessly scurry and swarm, often around our houses, kitchens and supposedly dirty hotels and restaurants.

We end up despising them for their natural behaviour, seeing them as nothing more than pests to be avoided, exterminated even.

But cockroaches have in many ways been given a raw deal.

Scientists are discovering that these supposedly crude, and creepy automatons are much more sophisticated than we thought.

By unveiling the secret lives of these insects, they are finding out that cockroaches are actually highly social creatures; they recognise members of their own families, with different generations of the same families living together.

Cockroaches do not like to be left alone, and suffer ill health when they are.

And they form closely bonded, egalitarian societies, based on social structures and rules. Communities of cockroaches are even capable of making collective decisions for the greater good.

By studying certain species of cockroach, we may even be able to learn some insights into how more advanced animal societies evolved, including our own.

Living Among Us

A small proportion of insect species are renowned for their social skills.

Ants, termites and some bees and wasps, for example, are "eusocial insects", which have highly developed social structures and behaviours.

But while cockroaches were known to be gregarious, based on their tendency to live in groups at various stages in their lives, we understood little about how they actually behave around each other.

Cockroaches that do not hang out with one another suffer "isolation syndromes". For example, young German and American cockroaches left alone take longer to moult into new larger forms and eventually become adults.

Their later behaviour is also severely affected; young isolated cockroaches find it harder to join a community and mate later in life.

Young cockroaches, it seems, need to be around and in constant physical contact with one another to properly develop.
