Spiders are possibly one of the most feared and disliked creatures in Australia, and contrary to the common opinion, they are not all dangerous nor are they all unattractive.
Spiders can be divided into two main groups:
Crawling or Hunting Spiders
This group of spiders are not fond on webs but commonly make their home under leaf litter or bark, in hollows or purpose built burrows and in general garden areas. Unlike the webbing spiders they hunt down their prey down or lie in wait to ambush their prey.
Control of crawling / hunting spiders is often limited to removal or elimination of each individual spider. Unless the species is considered dangerous, the best method of dealing with these spiders is to move them back into their habitat. Removal from premises can be achieved without harming the spider by the glass or bowl & paper/cardboard method.
Chemical barrier style treatments to stop crawling spiders from entering a premises are ineffectual. If chemical control measures were employed, these would need to be by direct application onto the spider.
Webbing spiders depend upon silk for their movements. When young spiderlings disperse from the parent web, they produce a strand of silk which is carried by the wind. The spiderling sits or hangs on to the silk and then builds its web wherever it lands. This process is known as ballooning. Mature spiders, when moving in search of food, produce a strand of silk which is carried by the wind until it comes into contact with a building or other stationary object. The spider then travels across this strand of silk and proceeds to build a new web. This is known as bridging.
Most common household spiders spin their webs over lamps, in curtains, railings, around windows and gutters, thus creating an unsightly appearance. Under some conditions, spiders are considered beneficial because they feed on insects. However the unsightly webs used to catch the insects usually outweigh the beneficial aspect.
Management of webbing spiders can take several forms. Management can include physical measures like trying to eliminate or reduce the food supply (insects) in the infested area e.g. moving or turning off external lights at night. Temporary measures can include the physical removal of webs, however this will not eliminate the spider population.
Most effective chemical management involves sprays that target the spider directly. Chemical on the webs is not always effective since most webbing spiders hang on using claw-like structures which do not readily absorb chemical residues.
