A special mix of food attractants is highly attractive to a wide range of stored product beetles & their larvae and is the key attractant. Tests have shown that these include: Grain Weevils, Rice Weevils, Maize Weevils, Lesser Grain Borers, Foreign Grain Beetles, Saw Toothed Grain Beetles, Drug Store Beetles, Merchant Grain Beetles & Flour Beetles. The all-round entry slit offers insects an attractive dark harbourage in which to seek shelter and is angled to encourage upward movement of the beetles. In the bottom of the trapping pit lays a filter paper soaked in wheat germ oil, which is another powerful attractant for a wide range of these beetles. Once the beetles fall on this surface, however, they get coated in the oil, which stops their escape. The oil also coats the insect’s spiracles that induces death…no messy glue used! Each lure cartridge is sealed to ensure it reaches you at peak attractiveness. The foil seal is simply pulled off and the cartridge is pushed into position on the Trapping pit/lure cartridge underside of the trap. The trap is then placed in position, close to machinery or other potential harbourages where beetles may be present the enclosed design of the trap means that it will remain effective in even the dustiest of conditions.The permanent trap, made from tough, injection-moulded polypropylene in ‘Food Industry’ blue. Disposable ‘lure cartridges’ which are designed for up to 6 – 8 weeks use.
