The three major pest species of rodents are the Norway Rat, the Roof Rat, and the House Mouse.
These three rodents are known as common pests, which describes their ability to successfully cohabit with man.
They are common in the main population centres in Australia and most countries throughout the world.
Since early times, rodents have been responsible for the loss and contamination of feed from crop stage through to storage.
Rodents have been associated with the transmission of disease organisms, the most notable being the occurrence of Bubonic Plague in Europe, causing the loss of 25 million lives.

To treat rodents, Pest Control uses:

Baits – often using brodifacoum and bromadiolone. While the black rat prefers moist foods (we use liquid baits), sewer rats prefer dry foods (we use cereal baits)
Traps – snap boards and sticky traps should be used as a backup for baits or for safety reasons. They should be placed just out from skirting boards, with the bait facing inwards. We use cocoa sprinkled on fresh bread. Tie the bread onto the metal with some cotton thread. Tugging will set off the trap
Gassing – is used in outdoor burrows, ships and grain silos by the use of fumigants
Proofing – this means the blocking of entry points by physical means such as bird wire, metal sheeting, steel wool or door seals
Contact Dusts & Gels – such as Bromatrol dust or Fentrol gel may be used once it is established where the activity is situated. You can determine this by the use of talc as a tracking dust
Prevention – good hygiene and a limited supply of food and water is the best for preventing rodent infestations
Rodents are repelled by the smell of mint, camphor and pine tar. Cats and dogs (especially terriers) are helpful for hunting small numbers of rodents in the early breeding stages.
