There are certain modalities of therapy that are fairly effective. I am also aware that some hypnotherapists have reasonable success.

The most common therapy used is a cognitive/behavioural desensitiation. This gradualy exposes the person to the feared object, first through pictures, until they can have an actual experience of meeting or touching the feared animal/insect/experience. It also looks at underlying assumptions around the fear. These assumptions are usually irrational.

It is important, with any phobia, to be aware that there might be elements of anxiety that need to be looked at and examined. Phobias can be one manifestation of a more generalised anxiety disorder. For this reason it is important that there is a proper clinical evaluation.

If there is a more generalised anxiety problem, a combination of SSRI's with cognitive behavioural therapy can be very effective.

I've seen some hectic spider bites recently. Most spiders are not dangerous in SA, but these were from violin spiders, and caused huge holes from necrosis of the tissue at the site of the bite. Best to fumigate your house regularly as prevention always better than cure.

Do you know what a wonderful cheap remedy is for mozzie bites - apply a dab of everyday toothpaste as soon as you discover you've been bitten and before you start scratching. Keep this up a few times a day and within a day or two the bite and itch will have disappeared. Not sure if it would work on spider bites!

Interesting, Jozigirl, about the toothpaste remedy for mozzie bites. Would you suggest Colgate or Sensodyne? :twisted:
Seriously, though, I have no idea what other types of bites this would work for. I'd imagine that any surface irritation due to the bite itself would get some relief from this method. However, it wouldn't be able to neutralise poisons, hence most probably would do nothing to help with dangerous spider bites.

Does anyone know how to distinguish between violin and button spider bites?

Hi there OWN.

The differences are something like this:

The Violin spider (Brown recluse spider) causes local tissue damage.

The bite is almost never felt. Because this spider is reclusive, it usually isn't seen either. The bite starts as a blister, which then becomes bloody. After 6-8 hours of a stinging sensation, there will be aching and severe itching at the area. In 2-3 days an ulcer may occur at the bite site. After 2-5 weeks, a rather noticeable hole in the skin can occur. The following symptoms may also develop after the bite: A deep blue or purple area around the bite, surrounded by a whitish ring and large red outer ring similar to a "bulls eye" may be seen.

Black widow spider (Button) bites release a toxin that can cause damage to the nervous system.

The bite is followed by intense local pain and the part becomes tender and apastic. Generalized muscular rigidity especially marked over the abdomen, pupillary construction, salivation, excessive sweating and cardiovascular collapse may follow. Double fang marks may be seen.

I hope this help! :thumbs_up:

Hi Folks
First... unless you see a spider bite you, it's difficult to diagnose a spider bite with a high degree of accuracy.

Second... I have every respect for the medical profession BUT they seriouly lack training in the identification of arthropod bites and stings. There are so many animals that cause necrotic lessions, which are often diagnosed as Violin spider bites evern though Violin spiders do not occur in that area.

Third... The emails you get regarding spider bites are all bogus rubbish. Ignore them. Violin spider bites are very rare in southern Africa even though the spiders are common in some areas. They do occur in houses in certain areas of southern Africa but generalyl speaking the are extremely rare in houses.

Fourth... Medical first line treatment a spider bite (or any other arthropod bite or sting) is often very easy and simple. As soon as you suspect you have been bitten, keep the bite site clean using antiseptics and chaning the dressing on a daily basis. Antibiotics may be neccessary in some cases. Pre-existing medical conditions may complicate any kind of bite or sting. Diabetics have compromised immune system and suffer from septicemia and a reduced immune system. Understand your medical conditions and understand how it can be affected. Having said this... when in doubt ALWAYS get professional medical advice.

Kind regards

****my apologies if this is a duplicate post****

3 Nights ago I woke up at around 3:30am. It was cold, a cold front coming and I went and turned on the heater. I climbed back into bed and was snoozing for about 20 mins when I turned my arm upwards to cuddle the pillow. It was then that I felt something squirming under my arm and then a light prick. I scrambled up, and in the red glow of the heater saw this black mass scurrying to the side of the bed. I jumped out and turned the lights on. I Immediately thought it was a rain spider but it was huge. Just to be sure I caught it in a cookie jar.
Half asleep yet bugged out I assumed all's ok and went back to sleep. I woke up at 7am, barely 3 hours later and was in excruciating pain. The gland in my armpit was the size of an acorn! I could not move my arm without pain, was unable to touch my gland. The bite spot was a little red but I had none of the really bad symptoms like tingling, dizzyness, numbness, headaches etc.
It was just my gland and any movement whatsoever was painful.
Went to the doctor and apparently it was some kind of secondary infection. Antibiotics worked wonders.
A dog may not be venemous but its bite, if left untreated, could potentially yield a nasty infection. Same goes for big spiders I guess.

Thats the critter, however, released her back into the wild.

Was it identified as a rain spider? We have had a few this season, but were told they were harmless!! The bite sounds very painful.

The venom itself is harmless to man, unless of course, there is some sort of undocumented allergic reaction to it.
Undoubetdly, what you experienced is lymphanegitis, or inflamation of teh lymph nodes in your armpit.

People who are not allergic to bee stings, have been known to experience the same reaction. Its normally manifested in 1 or 2 red lines on the underside of your arm, a tell tale sign of lymph inflamation.

The spider as far as I can tell is a rain spider, also known as "lizard" or "wandering spider" - Palystes spp. of teh sparassid family. Most likely a male, judging by the abdomen size. Femals typically have a larger, grape sized abdomen, increasing to thumb size when egg-carrying. These are the spiders we so often see teh nests of....a silk bag suspended by 5-7 threads, containing leaves, and small twigs etc. They have been known to use news paper, and indicates that for a spider, they are strong indeed.

I certainly have a healthy phobia of spiders, and these are the one that give me teh creeps. However, I can olny admire their make up.

Old English idiom : "If you wish to live and thrive....let the spider run alive"

Two points. (Or maybe more...)
The pic looks like a species of Palystes all right. (Rain spider, Lizard-eating spider, etc. Even called bobbejaanspinnekop, though they are not really; they are not even closely related.)

Very unusual to get bitten. You had accidentally alarmed it in your sleep. Naughty you!

In fact, like almost all spiders (except the Uloboridae afaik), Palystes definitely is venomous and produces a fair amount of venom, but not generally dangerously so. Our cat caught one and got his paw bitten. He came to no obvious harm, except that the paw swelled up to double its normal size. This puzzled him, but did not seem to bother him much. Next day it was nearly back to normal.

In his book "Wayward Naturalist in South Africa" Dudley D'ewes described how his wife got bitten properly by a female guarding her nest. She suffered some marked, but minor, neurotoxic symptoms. (The wife, not the spider; they let it go unharmed.)

No doubt greatly to your doctor's relief, I fully agree with his assessment and treatment. My point being that secondary infections are IMO a greater threat than venom in most cases of spider bite. When the really nasty bites cause tissue death and festering, I believe that the poison just starts the damage and the injected bacteria aggravate and extend it, sometimes for months. IMO it is then far more important to apply the antibiotics, early and vigorously, preferably by injection, and never mind the antihistamines.

FWIW!

Jon

Hi all,

As a previos person stated a lot of spider bites are blamed on the Violin Spider. However it is difficult to identify the spider as the spider is either gone or crushed and can't be identified. Doctors can treat the infection caused by the spider bite but can't neutralize the spider venom as no antidote excist in the whole of the western world. Normal practise will be to treat the spiderbite according to simptoms which can differ substantial from person to person as with any other insect bites depending on the persons alergic reaction to the specific insect venom and the severity of the infection. I had a very bad experience personnaly with a spider bite and nearly lost my leg. The problem is the infection can be treated but the venom still stay in your system. The after efects can start shortly after the bite or can take a few years and then be contrubuted to something new whith the spider bite long gone and filed away in the past.

I am not a doctor neither am I trying to give any medical advice but any person bitten by a spider, insect or reptile who suffer from after effects or suspect that they suffer from after effects can contact me for further discussion and reveral for a possible sulution. I suffered for 8 years beleive me it cost me dearly and if I can assist any one I will do so. A number of people will remember my story as it was published in the Lowvelder at the time.

It is tru that not many people in South Africa get bitten by spiders therefore the knowledge base for treatment is very limited and our doctors do the best they can with what is available to them.

It is also tru that several people lost there feet, arms or legs and in a few cases there lifes don't fool yourself when the infected area is healed the venom is still in your sistem

Regards,
Wandelstok

A very HOT welcome to the forums, Wandelstok (nice name too :clap: )!

Thanks you for the extra information - I believe one can never have too much info! :thumbs_up: And thanks for making yourself available for discussion as you, unfortunately, suffered it first hand.

It is a sad story that you suffered so long. :( Are you completely healed now? Eight years is an unbelievably long time and I think very few people would even consider that the after-effects can continue even a tenth as long as that!

I once saw a man with the after-effects of a spider bite (he said it was a violin spider) that had endured at that stage for two years. The hole in his leg was not healing and was probably the size of a man's fist! The doctors had tried everything they knew and he had specialised dressings that he had to plug into the wound on an ongoing basis.

I have not seen him since, but based on other reports and people I've spoken to, that wound probably will never completely heal.

I think we underestimate the effect that some animals can have on our systems, and so being vigilant is probably our best defence to minimising being bitten in the first place.
