Please leave the spider webs for a couple of weeks before removing to allow the treatment to work fully.Ĭlotheslines, which should be clothes free, are treated along with outbuildings and letterboxes along with any pot plants and other likely spider harbourages. The external perimeter walls, eaves, verandahs, etc and spider webs are all also sprayed. Very safe synthetic pyrethroids are applied to internal skirtings and other likely harbourages. Our treatment will usually involve the application of a pesticide dust to the roof void, in and around cavities of external windows and doors etc, and under the building (if access is available). We suggest you spray the spider directly with a surface spray or vaccum them up or place in a container using gloves and place outside should they enter after a treatment. ![]() We therefore can’t guarantee spiders will not enter the building after spraying. There is no web to return to and should they not be directly sprayed during the treatment they can simply walk into the building with no ill affect. Therefore when we apply residual chemicals to surfaces we cannot rely on these Nomadic spiders coming in contact with the spray unless they decide to rest down on the treated surface, which is very rare. Spiders are affected when a pesticide is absorbed through their body surface (Cuticle). They hunt their prey and roam from area to area. Unfortunately nomadic spiders such as Huntsman and Whitetails do not have webs. ![]() Exopest do not recommend spraying for ground dwelling spiders, eg trap door spiders, wolf spiders When to treat?Īt Exopest we would like to explain that a spider treatment in general these days will only effect web spinning spiders, since we are able to sight the webbing and apply pesticide directly to their harbourage and webs. Huntsman are actually very good predators of small iinsects in the home and clean up many unwanted biting insects. In domestic situations Redback spiders and Whitetails are generally regarded as harmful and whilst Huntsman spiders are large, fast and look menacing, the fact is no spider tends to bite unless provoked. The female spider is normally larger than the male. Some spiders have venom that is dangerous to man (Sydney funnel-web, Redback etc) and all spiders grow from an egg some even carried on the back of the female. All spiders make silk and all spiders bite in order to feed. Their bodies are in 2 parts head and abdomen. Spiders are invertebrates (no skeleton) and grow by shedding their skin or cuticle. However there are a hundreds of different species some that should concern us and others that cause no harm. And usually does.We are all generally familiar with spiders having 8 legs and usually associated with webs. (Redbacks are one of the few 'sex cannibalistic' spiders.) But the female has a softer side – she would die for her offspring. Females tend to stay in one place most of their lives, shedding their exoskeleton up to eight times.Ī male attracts a female by plucking on her web and doing a courtship dance. (As the song goes.) Females lay hundreds of eggs at a time because many of these will either be eaten by their siblings or die from a wasp parasite.įemale redbacks live for around three years, while males only live for seven months (remember they are part of the 'widow' family of spiders). ![]() Once it emerges from the egg sac, it does whatever a spider can. A hatchling emerges from its egg after about eight days, then spends another 11 days or so inside the egg sac. Where does life begin for a redback spider?Ī female lays her eggs inside a silken egg sac in her nest. Not only are they dangerous to humans, but they can also be fatal to one another! Find out about the mating habits of redback spiders, and why mating is a matter of life and death for male redbacks. They are famous – or rather infamous – for being highly venomous. YEARS: F–2, 3–4, 5–6 Have you heard of redback spiders?
