One of the safest and most humane poisons available for controlling problem populations of birds is alpha-chloralose. This substance produces a hypnotic effect by anaesthetising the brain of affected animals. In this condition, the body temperature control mechanism does not operate properly and affected animals may die from a low body temperature.
Alpha-chloralose is controlled under the
Agricultural and Veterinary Chemicals (Control of Use) Act 1995
and may only be used by persons who hold a specific permit. Application for a permit may be made by contacting Biosecurity Tasmania on 03 6165 3777 (Statewide), or by submitting a completed
and the prescribed fee.
Alpha-chloralose is available from Rentokil for the control of pigeons and sparrows by permitted users. Other species of birds may also be controlled using alpha-chloralose. However, these operations must be assessed and supervised by an Invasive Species Management Officer of the Department of Primary Industries, Parks, Water and Environment.
