Spiders are considerably different to insects as they consist of 8 legs instead of 6 and they have two body segments instead of 3, as the head and thorax are combined into one which contains the eyes, mouthparts and legs.
The most common species relevant to us are the Huntsman, Jumping, 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 which depend solely on webbing to snare their prey seldom move very far and mostly hide in a crevice, curled leaves or 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 is usually caught and consumed by the female.
The venom is not necessarily poisoness to warm – blooded mammals but some are able to cause death by injecting an extremely toxic substance into the bloodstream of warm blooded animals. 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 to cracks and small openings, rough surfaces by application of a liquid spray to harbourage areas will provide a respite for 3 months or so. In areas where there are numerous trees. Two treatments should be considered during the summer months.
