Permethor Shield is the latest innovative product from Ensystex providing material protection from timber and fabric pests. 


Permethor Shield is the latest innovative product to be launched by Ensystex. Permethor Shield is a low odour emulsion concentrate insecticide that provides long-term control of a broad spectrum of insect pests in a wide range of situations.

Ensystex’s regional director, Steve Broadbent explained, “Permethor Shield is unique in its low odour approach in this protection segment. It is particularly effective for controlling timber pests including timber borers (beetles) and drywood termites such as Cryptotermes brevis, C. primus and C. domesticus. It then provides ongoing long-term protection against reinfestation.”

Permethor Shield is also approved for protecting carpets and other fabrics from pests such as fleas, silverfish, carpet beetles (Anthrenus spp.), webbing clothes moths (Tineola spp.) and case-making clothes moths (Tinea pellionella), together with the control of general insect pest species in and around properties.

Mr Broadbent added that Permethor Shield is also one of the few products approved for protecting aircraft from various pest species, including pests of quarantine import. It is also labelled for fabric and clothing repellent treatments to protect against mosquitoes and biting flies.

Offering maximum flexibility, Permethor Shield can be diluted with water, deodorised kerosene or non-staining light oils.

“When using Permethor Shield we recommend pest managers commence with a thorough inspection before treatment,” said Mr Broadbent. “Certain drywood termite species, such as C. brevis, are notifiable pests, and it is important to ensure identification of frass is completed before treatment to determine if this species is present. Given it is approved for direct treatment of timbers, carpets and fabrics for long-term protection, it is also a good idea to ensure the diluted product is compatible with the materials to be protected by testing a small area first.”

Prior to treatment for drywood termites and borers, timbers should be cleaned and lightly sanded for best results and to allow absorption of the solution. With borers, damaged areas should be drilled, and the solution injected into the timber until it is unable to absorb more liquid. All infested areas, as indicated by the expulsion of frass, must be treated for maximum effect.

“A single application is usually sufficient, with continued expulsion of frass often due to movement of the timber, rather than reinfestation. The level of penetration will be improved if Permethor Shield is diluted with deodorised light oils when treating for timber pests,” advised Mr Broadbent.
