Abstract: An insect feeding station (10) for administering a fluent substance such as a poisonous liquid bait to ants and other insects. The feeding station (10) comprises a housing (11) having an interior region (21) adapted to contain the fluent substance. The housing (10) has an opening (27) through which insects can enter and leave the interior region (21), and an internal structure (43) within the interior region (21) for facilitating access by the insects to the substance. The internal structure (43) may take various forms but typically is of a construction which is adapted to at least be partially covered by the substance when the latter is first introduced into the interior region (21) and which is progressively exposed as the substance is consumed. With this arrangement, the portion of the internal structure which is exposed provides a zone away from the liquid bait for supporting the bodies of dead insects. Thus the bodies are "dry-docked" on the internal structure from where they can be retrieved.

Abstract: An engaging device for releasably engaging an object. The engaging device comprising a supporting part and an engaging part mounted on the supporting part for pivotal movement about two spaced apart axes between two stable conditions, one being an engaging condition and the other being a release condition. The two axes being defined by means carried on a portion of the supporting part, the supporting part being resiliently deflectable at said means defining the two axes to accommodate movement of the engaging part between the two stable conditions and to urge the engaging part into one or other of the two stable conditions. The supporting part may define a housing which accommodates the engaging part and which provides protection to the resilient portions of the device.

Abstract: An engaging device for releasably engaging an object. The engaging device comprises a supporting part and an engaging part mounted on the supporting part for pivotal movement about two spaced apart pivot axes between two stable conditions one being an engaging condition and the other being a release condition. The engaging part comprises two spaced apart arm portions and an elongated bridge portion extending between the arm portions, and means for causing the engaging part to in use remain in the engaging condition in response to the application of a pulling force between the object and the engaging device.
