Spiders are a reality of Australian life, but a great majority of them are not dangerous. In most cases, sensible precautionary measures will keep you safe from spiders. For example, do not leave clothes or shoes outside at night, wear appropriate clothing such as gloves when working in the garden and don’t walk outside at night barefoot. Teach children to never touch spiders – and follow suit yourself. Repair cracks and crevices and cover vents and weep holes (the small holes cut into brickwork that allows moisture to escape) with mesh and attach flyscreens to windows. Keep external lights switched off at night, as these would otherwise attract insects, which in turn will attract spiders. If you do find the odd lone spider in the house, and you are very sure that it is not poisonous (such as a huntsman), return it to the great outdoors by using a glass jar and stiff piece of paper to catch and transport it.
A professional pest controller like (Us) we do a thorough inspection of your property, check all likely habitats such as corners of windows, along cornices and be skirting, behind curtains, in ceiling voids, gutter lines, outdoor furniture, and garden areas, and advise on potential entry points. If dangerous spiders are found, talk to us about what options you have. The use of chemicals may not be the best option: spraying spider webs and using chemical barrier-style treatments against crawling spiders may not be particularly effective.
