Spiders are different from insects as they have eight legs instead of six and they have two body segments instead of three, as the head and thorax are combined into one that contains the eyes, mouthparts and legs.
The most common species of spider relevant to us here in Brisbane are the huntsman, jumping spider, St Andrews Cross, redback, white-tailed, wolf and funnel-web.
Most spiders are nocturnal and only appear during the day if they have been disturbed in some way. Different species share different characteristics, habitat and prey techniques. Those that depend solely on webbing to snare their prey seldom move very far and mostly hide in crevices, curled leaves or are camouflaged as twigs. Hunting spiders are a lot less dependent on webs and mostly travel for food.
Males seek out the females at mating time and drop their sperm on the ground, bark or in webs specially made for this purpose. The male picks up his sperm with his long palps alongside his jaws (specifically used for this purpose) and places it into the female spiders’ genitalia. After mating the male in some species is caught and consumed by the female.
Spider venom is not necessarily poisonous to mammals but some spiders are able to cause death by injecting an extremely toxic substance into the bloodstream of warm-blooded animals. However, most spider bites result in no more than localised swelling or irritation.
Treatment methods available:
Most spiders form nests on the exterior of structures by spinning webs. Treatment of external surfaces of buildings and to cracks, small openings and rough surfaces is by application of a liquid spray to all these harbourage areas; this will provide a respite for three months or so. In areas where there are numerous trees, two treatments should be considered during the summer months.
