Abstract
A device is provided for the collection and disposal of insects and similarly sized detrital objects. The device includes an air inlet end through which air can be entrained, and an air outlet from which said entrained air is expelled. The device also includes a hollow duct portion through which entrained air passes and a filter means provided between the inlet and the outlet which prevent insects from being expelled through the outlet. Means are provided to create a pressure differential between the air inlet and air outlet of the device, such that air is entrained in the inlet and drawn through the duct portion of the device towards the outlet, additionally passing through the filter. The pressure differential is sufficient to entrain air, insects and/or detritus into the duct portion and the air path defined through the device is substantially unhindered so that entrained insects and detritus can escape from the device along the same path by which they were entrained ultimately exiting from the inlet end of the duct when the pressure differential is reduced, eliminated or reserved.
