While the elimination of spiders from your property is a simple task, gaining treatment contact of all of the spiders residing in your home, can be a bit of a challenge.
For the best control of spiders, a simplified analogy will help the pest manager to adopt the most effective treatment strategy. Let’s just say that spiders only eat with the use of their fangs, and that they do not consume any toxins which may come in contact with their feet-all 8 of them. Now this is a relatively simple and not entirely true analogy, but means, is that residual treatments are less likely to work, and that spiders should be physically contacted with the treatment products applied, i.e. they should be directly sprayed or dusted.
So having said that, location of likely spider harbourage areas should be identified, prior to the treatment. In most cases, this is fairly simple, as spider webs will give you a good indication of where spiders are living.
Again, the integrated approach using Biforce 100SC liquid insecticide, and PermForce Insecticidal Dust, or Permethrin D 2kg Household pack, is going to provide you with excellent results.
A thorough dusting of the ceiling, and wall cavities, and possibly subfloor spaces, followed by a crack and crevice dusting, internally and external of the building will help to contact the concealed spiders lurking in the roofspace, subfloor and behind brickwork and gyprock walls. A light spray of the internal skirting boards, and a slightly heavier treatment of all external surfaces including doorways, under eaves, around downpipes and guttering, pipework outdoor furniture and bbq’s.
This method of treatment works in more than one way. Whilst it will eradicate spiders on contact, it will also help to reduce the presence of other insect pests, which create part of the spiders food source. In turn removing the spiders source of readily available food. Spiders can drop in at any time, and whilst their removal is quite simple, there is currently no treatment which will stop them from coming back entirely, so this treatment is one which may be required on a 6 monthly basis or more, dependent on the surrounding environment.
