PERMETHOR MAGNETIC sets a new standard for more effective dusting treatments.

PERMETHOR MAGNETIC employs an exceptionally light powder formulation, designed to flow deeper and further into voids and crevices. The big performance difference comes from the incorporation of our patented magnetic component, Magthanite® into PERMETHOR MAGNETIC to provide faster kill and improved transfer due to its magnetic properties.

Many species of insects have been shown to use the earth’s magnetic field to help them to orientate and navigate. This appears to be linked to the presence of particles of magnetite in their bodies. Magnetite is a powerful fer­romagnetic substance that generates its own magnetic field.

Due to this magnetic charge on the insect exoskeleton, by incorporating our patented magnetic component into PERMETHOR MAGNETIC, it enables the dust to adhere more readily and strongly to the tarsi (lower leg segments) of insects. The original trials took place at Southampton University; with more advanced studies conducted at the Rothamsted Experimental Station in the UK, confirming that insects passing over a residual deposit of Magthanite picked up an average of 56% more particulate material than those passing over a deposit of inert talc, with up to 250% more product, trans­ferred between the insects.

Trial data submitted to the APVMA for the registration of PERMETHOR MAGNETIC, confirmed it provides significantly faster control of insects, when compared to a positive control without the magnetic properties. This is due to the improved pick-up of the dust by insects and the transfer effect created by the magnetic component.

PERMETHOR MAGNETIC is ideal for areas where liquid based formulations are not suitable. This includes large voids or areas where there is a risk of corrosion or spray drift to electrical equipment. For best results, in roof or wall voids, apply using a power duster. PERMETHOR MAGNETIC is most effective when a fine coating only is applied. Only the lightest application is needed, and pest managers should avoid ‘mounds’ of dust as insects will not pass through these. PERMETHOR MAGNETIC is also ideal for use as a flushing agent during inspections to identify cockroach harbourages.

With the environment in mind, PERMETHOR MAGNETIC is exempt from Poison Scheduling (SUSMP) and supplied in 5 kg recycled cardboard cartons.
