Spider Control - Beware of Brown Recluse, Black Widow Spiders


Source: http://www.emaxhealth.com

Spiders can be found in nearly every corner of the world, except Antarctica, but the spiders most people worry about are the ones lurking in the corners of their homes, like the brown recluse or black widow. A brown recluse spider has been named as the possible culprit in the recent case of Victoria Franklin, a woman living in Georgia who lost her breast from gangrene after being bit by the arachnid.

black widowAccording to The World Spider Catalog, there were 41,253 species of spiders identified as of December 16, 2009, but only a few are dangerous to humans. Two of those dangerous spiders can be found in the contiguous United States, and especially in the southern states where Ms. Franklin lives: the brown recluse and the black widow. These spiders prefer a warm environment and dark, dry hiding places where they can be left alone, like closets and woodpiles.

Although a great many people fear spiders (some to the point of phobia, called arachnophobia), the creatures do much good by capturing and eating other insects. Even though all spiders have some amount of venom that varies in potency, the vast majority of spiders are not dangerous to people because their fangs are too short or too fragile to penetrate a person's skin.

A spider generally bites a person because it has been frightened or disturbed in its hiding place and it is trying to defend itself. In brown reclusemost cases, a bite mark from a spider is too small to be seen easily, and often people do not remember being bitten.

According to the California Poison Control System, spider bites typically cause pain, small puncture wounds, redness, swelling, and itching that may last a few days. It is rare for a spider to bite more than once, so if you have multiple bites, you have probably been bit by fleas, bedbugs, ticks, mites, biting flies, or another insect.

The black widow spider bite is serious, but it is rarely lethal. If you see the spider, it has a red hourglass mark on its underside. A bite from a female black widow spider results in slight swelling and faint red marks initially, and then within a few hours intense pain and stiffness set in. Other signs and symptoms include chills, fever, weakness, headache, elevated blood pressure, nausea, vomiting, and severe abdominal pain. Those at greatest risk of developing symptoms are young children, the elderly, and people who have high blood pressure.

In many cases, the spider does not inject venom and no serious symptoms develop. If muscle cramps develop, you should seek medical care for treatment of the symptoms. A black widow spider antivenin is rarely necessary but it is available.

Crickets 'Forewarn' Unborn Babies About Spiders


ScienceDaily (Feb. 17, 2010)

Just because cricket moms abandon their eggs before they hatch doesn't mean they don't pass wisdom along to their babies. New research in the American Naturalist shows that crickets can warn their unborn babies about potential predator threats.

Researchers Jonathan Storm of the University of South Carolina Upstate in Spartanburg and Steven Lima of Indiana State University placed pregnant crickets into enclosures containing a wolf spider. The spiders' fangs were covered with wax so the spiders could stalk the crickets, but couldn't kill them. After the crickets laid their eggs, Storm and Lima then compared the behavior of those offspring to offspring whose mothers hadn't been exposed to spiders. The differences were dramatic.

When placed into a terrarium with a hungry wolf spider, the crickets born of spider-exposed mothers were more likely to seek shelter and stay there. They stayed hidden 113 percent longer -- and as a result had higher survival rates -- than offspring from mothers that hadn't been exposed to spiders. Another experiment showed that the "forewarned" crickets were more likely to freeze when they encountered spider silk or feces -- a behavior that could prevent them from being detected by a nearby spider.

Spiders - Rare spider glides into Wales – for the fishing


Fen Raft spider

IT'S one of Europe's largest and rarest spiders, it feeds on fish caught as it floats menacingly on streams and canals - and it's thriving in Wales.

One of only three UK populations of the rare fen raft spider has been observed on a waterway in South Wales - sparking intrigue among scientists about how the unusual species arrived in this part of the UK.

Until recently, the "fishing" spider - which is around 3in long and uses tiny hairs on its legs to glide over the surface of water - was found only on fens in Suffolk and Norfolk.

But seven years ago, one of the arachnids was spotted at Llandarcy, near Neath.

But now a population of them has been found on the Tennant Canal at Pant-y-Sais Fen, near Jersey Marine, Neath - allowing producers of a new wildlife documentary to obtain rare footage of one.

 The shots, recorded for the S4C series Tir Cymru, shows a hugely pregnant female raft spider near the Tennant Canal.

The programme, presented by naturalist Iolo Williams, follows the rich wildlife to be found on the routes of old roads, railways and canals in Wales.

Mike Clark of Bridgend of the South Wales Wildlife Trust, made the initial discovery of the fen raft spider in Llandarcy around seven years ago.

Spiders - Giant Spider Species Spied in Sand Dunes


Source: FOX News 

With a lanky legspan of up to nearly a half foot, a newly discovered spider species is the largest among its family of spiderarachnids in the Middle East.

The spider, now dubbed Cerbalus aravensis, was discovered in the dunes of the Sands of Samar in the southern Arava region in Israel by a team of biologists from the University of Haifa-Oranim. The scientists say C. aravensis is nocturnal and mostly active during the hottest months of the year.

It constructs underground dens that are sealed off with a lifting door made of sand particles glued together to camouflage the living quarters. The spider's legspan is estimated to be about 5.5 inches.

Spiders - Tarantula Owner Sees Red After Hairy Moment


Lulu Sinclair, Sky News Online

Tarantula lovers are being warned to avoid getting up close and personal with their pet - or else do it from the other side of an aquarium pane.


Chilean Rose tarantula

A Chilean Rose tarantula spider

That is a lesson that a 29-year-old man from Leeds in Britain learned the hard way, according to the medical journal, The Lancet.

In February of last year, the man turned up at St James's University Hospital in Leeds after three weeks of stinging pain in one eye, which had become red, watery and light-sensitive.

Doctors prescribed antibiotics, assuming he was afflicted with a particularly stubborn case of conjunctivitis, but the treatment did not help the symptoms.

When they re-examined the patient with high-magnification lenses, doctors spotted ultra-thin, hair-like projections sticking into the cornea.

They were so small that even microforceps could not remove them.

That is when the man recalled a close encounter with his pet spider shortly before his eye first became irritated.

While cleaning a stubborn stain on the glass tank that was home to his Chilean Rose tarantula, he turned his head to find the fist-sized arachnid very near by.

Lets get a better understanding Why this happened...

As a keeper of Tarantulas and owner of a Chilean Rose Hair (G. Rosea), I know about this breed, most importantly what to do and not to do. Rosies are considered to be docile but very skiddish, they are also known for changing their personality after each molt.

The Rosies main defense is flicking hairs (Ulticating hairs)from their abdomin as a "Stay back" warning. This gentleman should not of had his head inside a tarantulas enclosure! Anytime you are working inside of the enclosure you should gently stroke the rear leg to let it know you are near (Tarantulas have very poor eye-sight). 

Although the G. Rosea is a great starter Tarantula they do change personalities, handling should for the experienced handler and even then eye glasses or some form of eye protection is recomended as well as washing your hands afterwards.

Spiders - Jumping Spiders


Jan 1st, 2010 by Karthik  

Here come the Salticids to herald in the New Year and to give you all a jumpstart into 2010!

Not all spiders build a web and wait patiently to trap their meal! There are some that pounce on their prey and rely on their keen eyesight to catch their prey. These are the jumping spiders.


The jumping spiders are wary of anything that happens in their vicinity. One can observe them respond even to slight movements close to them. The jumping spiders are able to do this due to the four pairs of simple but special eyes they possess. One pair is large, pointing forward, giving it a sharp sight. In fact, at a distance of about one foot, these spiders can distinguish between prey, predator, etc. Alongside is one other pair that is smaller and pointing forward. The other two pairs are placed further behind and are strategically located.

Jumping spiders are active hunters. Once a potential prey (mainly insects) has been identified, they advance slowly and stealthily towards it. When within jumping distance, they jump on the prey and grab it. Before they jump, they secure a strand of silk as a lifeline to the substrate. This way they can crawl up to safety if the jump is a failure!

Pest Proofing This Winter Can Keep Rodents and Other Pests Away


National Pest Management Association Offers Tips to Protect Homes from Pests in Cold Weather

Press Release Source: National Pest Management Association (NPMA)

FAIRFAX, Va.--(BUSINESS WIRE)--For many homeowners, pest proofing is a chore relegated to the warmer months of the year. But many pests gain entry into homes in the winter as they seek shelter from the cold weather. In fact, according to the National Pest Management Association (NPMA), rodents alone invade an estimated 21 million homes in the U.S. each winter.

With 24% of homeowners reporting mice infestations specifically in the winter, they are among the top pest issues of the season. Mice and rats spread diseases like Salmonella and Hantavirus when they contaminate food, and bring fleas, ticks and lice indoors. Rodents can also cause serious structural damage by chewing through wood and electrical wiring.

Other winter invaders pose health threats, as well. Cockroaches and ants contaminate food sources, and cockroaches can trigger asthma attacks in children. Spiders bite when they feel threatened, causing serious reactions in some people.

Spider Control - Worlds Deadliest Spider


In the US we have our share feared spiders, the Brown Recluse, the Hodo Spider and the Black Widow, all with venom that packs a serious punch, each requiring medical attention. These 3 can be aggressive but like most arachnids really do not want any thing to do with you unless your prey.

So what Spider as been dubbed the Deadliest? Well this Spider is native to South America Amazon and seems to like stowing away in banannas being shipped throughout the world. This spider is called The Brazillian Wandering Spider. What makes this arachnid deadly is that, as the name implies, it wanders the jungle floor at night to hunt and during the day they hide inside termite mounds, under fallen logs and rocks, and in banana plants and bromeliads. This Spider is known to hide in dark and moist places in or near human dwellings. When hunting this spider has been know to attack first and ask questions later, completely unprovoked.

The bite from the Brazillian Wandering Spider can be fatal to bothwandering spider children and animals, in any event both would require immediate medical attention and antivenom. A bit to an adult can cause severe problems and as well should seek medical attention immediatly.

This Spider has been spotted and captured in bunches of bananas, from the US, to the UK and even Denmark. Each one has been captured by produce clerks and even grocery store managers and have been turned over to professionals who study arachnids.

Ask the Tarantula guy...


Over the last few months I have recieved a few emails from our blog visitors about Clark's Tarantula page "Charli the Tarantula". Now I am not a trantula expert, an entomologist, nor do I claim to be, I am just a hobbiest/keeper but I will answer a few questions from our readers.


Hi Clark,
Why did you name your spider CharliCharli is a boys name but you have a girl.

Sarah H.
Portland OR

Hi Sarah!
Charli is actually short for Charlotte! It is funny since the Founder of Clark Pest Control is Charlie Clark. Thank you for writing in!


What do they eat? do they bite? can anyone own a tarantula?

Jeff S.
Carmel CA

HI Jeff,
Tarantulas eat mostly crickets but a lot of keepers go with Dubia feeder roaches. As far as biting yes all tarantulas can bite, but the question is do they? well, new world tarantulas will flick tiny hairs from their abdomin first, if the predator does not back off then the tarantulas will go into a threat posture ready to strike, on an occasion they will. Old world tarantulas bite first then ask questions later!

Can anyone own a tarantula? absolutely yes, but if you are planning on purchasing one make sure you do your research, your looking for beginner spider such as the G.Rosea (Rose Hair Tarantula), B.Smithi (Mexican red Knee) or a B.Albopilosum (Curleyhair) all 3 of these are great for beginners and docile! Good luck.


what tarantulas are really aggressive, the one to stay away from.

David S.

here are a few that only experienced keepers should consider. I personally will not keep anything aggressive, it goes much further than just handling, Tarantulas require constant maintenance to their cages, change out the water, pick up the remains left over from their last meal and etc. aggressive ones make it tough to do this. Here are a few for ya!

1. P. Cancerides (Haitian Brown) Very Angry Tarantula DO NOT HANDLE P. Cancerides
2. C. Sericeus (Rangoon Mustard ) Aggressive, hisses and called the Pit Bull of Tarantulas DO NOT HANDLE C. Sericeus
3. S. Hoffmanni (South American Horned) DO NOT HANDLE . Hoffmanni
4. M. Zebratta (Costa Rican Sun Tiger )Extremely FAST and aggressive DO NOT HANDLE M. Zebratta
5. C. Darlingi (East African Horned Baboon ) This one aggressive and usually has a sever bad attitude DO NOT HANDLE C. Darlingi

If you have a question please let us know!
