Can we trap or lock out rats from our home?

Put simply…No. Rats are very tenacious animals with very high intelligence. They will simply find a new entry point or points, and if none are available they will just chew themselves a new one. This is the cause of damage that you should try to avoid. Rats are an introduced animal to Australia. They are feral and in extremely large numbers, especially when close to fresh underground water such as a sediment pit, (which on most occasions you don’t know is even there, the rats do however) and thrive at these locations. Rats are by far the most prolific of introduced animals in Australia, by population and effect, the native wildlife and fauna suffer significantly as a result.
