How can I tell if there are animals in my roof space and walls?

If you are hearing noises, then you certainly have something residing within your building. Loud heavy footsteps indicate a larger animal such as possum, whilst lighter, faster, currying type sounds and scratching would indicate more the presence of a rodent colony. It is best, however to have your building inspected by a professional before deciding on the treatment as possums are protected by law against harm and baiting can have serious side effects when performed and there is a chance of wildlife presence. You must ensure your building is completely sealed off to possums and other wildlife BEFORE PLACING ANY POISONS within it. Laying baits externally, even if within a “Baiting Station” is dangerous to wildlife, pets & children and should be avoided at all cost. They will also serve to attract rodents to your property that have no previous reason to be there.
