![]() ![]() 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. We are all generally familiar with spiders having 8 legs and usually associated with webs.
