Spiders


Huntsman Spiders

This common name covers around 100 different species. Most live outside under bark and hunt prey at night. They often enter houses but are usually timid and placid.

St. Andrew’s Cross Spider

These are a range of spiders that share a similarity in their web building. They are most common in the garden and found throughout Australia. They are considered harmless and will only produce a mild local pain if bitten.

Golden Orb Weaving Spider

This Golden Orb spider gets her name from the fantastic golden web that she makes. The webs are so strong they can even entangle small birds, but the spider only eats small insects.

White Tail Spiders

Famous for supposedly causing large skin ulcerations and necrosis, white tail spiders are a concern for many people. The truth is that the spider’s bite will generally only cause a small swelling which may blister. The more dramatic reaction is possibly caused by a micro-organism which may be carried on the fangs of the spider. The reported necrotic reactions have only occurred on a very small number of people. White Tails eat other spiders, particularly Black House spiders.

Redback spiders

The Red-back is Australia’s best known spider. They can live almost anywhere but do especially well in the man-made, disturbed environments. Red-backs are prodigious breeders. Each female makes several egg sacs in a year and produces up to a thousand eggs. In warm conditions when there’s plenty of food Red-back numbers can explode. Untidy webs may contain white pea-size sac. Hundreds of Red-back spider bites are reported each year, but less than 20 per cent require anti-venom treatment. Only female Red-back spiders bite people. Male spiders are only a tenth the size of females.

Sydney Funnel Web Spider

Australian funnel webs are restricted to the south-east of the continent, and mainly in coastal areas. There are at least 40 different species, and not all are dangerous, unlike the notorious Sydney Funnel-web spider. Some Funnel-web's venom can have a severe effect on primates (like humans, apes and monkeys). However it has little effect on other mammals like cats, dogs or kangaroos. Thirteen deaths have been recorded from Sydney Funnel-web bites in Australia. Male Funnel-web spiders are about five times more venomous than females, so are probably responsible for these fatalities.

Female Funnel-webs take 3-4 years to mature and may live as long as 20 years. Males mature in 2-3 years and wander about looking for a mate for 6-9 months before they die. Male Funnel-webs are also more active in summer than winter. Despite rearing up in an impressive threat pose, Funnel-webs can't jump. Unlike some spiders they cannot swim either, but can stay alive in pools for many hours supported by air bubbles trapped amongst their body hairs (eventually they sink and drown).

Treatment Method - Depending on the type of spider involved, possible treatment methods include applying a residual insecticide to harbourage areas around the property.

Treatment Time - Approximately 45 minutes to 1 1/2 hours.

Note - Occupants must leave the property for approximately 2 hours after treatment has been carried out.

Warranty Period - 3 months.

TREATMENT FOR A VENOMOUS SPIDER BITE

In cases of spider bite from a highly venomous spider, or if there is concern about a spider bite, the victim should be kept as quiet as possible - even walking should be kept to a minimum. Excitement or activity increases heartbeat and therefore circulation of the venom. A broad, firm bandage (not a tourniquet) may be applied over the wound on the heart side of the bite, especially if there is likely to be a delay in obtaining medical help (except for red-back spider bite - see below). An ice pack applied to the bitten area will help reduce the circulation at the bite site and also the associated pain. In case treatment is necessary, take the spider with you (in a jar), so that the medical staff can determine the type of treatment required.

TREATMENT FOR RED-BACK SPIDER BITES

  1. Loosen or remove tight clothing and make the patient as comfortable as possible, preferably lying down. As the fangs of the red-back spider are so small, the venom is placed just under the skin and the application of a firm bandage is not recommended.
  2. If the victim is perspiring freely, give fluids (not alcohol).
  3. Take the victim to a hospital as soon as possible.
  4. Remember - stay calm.

Anti-venene is administered if the bite is definitely from a Red-back Spider and only then if the patient shows clinical signs of venom absorption.

TREATMENT FOR LESS VENOMOUS SPIDER BITES

Clean the wound thoroughly with soap and water. Keep the patient under observation for an hour or more and, if his/her condition deteriorates, seek medical aid. A doctor can give treatment to prevent possible secondary infections and tetanus.
