Signs of rodent presence

Signs Of Rodent Presence

Home owners will normally be aware of the presence of rodents in their dwelling but occasionally the signs are less obvious. As a pest controller, you may be asked to do an inspection and will have access to parts of the home the owner rarely inspects.

By posting the following signs of what to look out for on your website or in articles, you may even draw the home owner’s attention to a problem they were unaware of, and hopefully get customers.

Signs to look for:

  • Piles of black droppings, between 5 to 18mm in length.
  • Nibbled or partly eaten fruit and nuts.
  • Small bones left in secluded places, such as the corner of a shed.
  • Holes burrowed in the ground near buildings or compost heaps.
  • Signs of damage to wood, cables or plastic caused by gnawing.
  • Food packets and pet food containers may also show signs of gnawing.
  • Scampering or scratching sounds coming from behind walls, under the floor or from the roof.
  • Nests in the roof.

Understanding The Rodent

Rodents are mammals which have a single pair of incisors in both the upper and lower jaw. These teeth never stop growing, meaning that the rodent needs to gnaw constantly in order to keep the length of the teeth in check. Their name comes from the Latin rodere, which means ‘to gnaw’.

Making up about 40% of all mammals, rodents are found on every continent except Antarctica. Most cause no problem to mankind and spend their lives out of sight. A few rodents have become able to adapt to almost any living condition, using mankind as a way to increase and spread. These include rats and mice.

In Australia there are 64 native species of rodent and none pose any threat to people. In fact, we are the ones who threaten their existence. But three species of rodent have been introduced that are causing significant trouble through their destructive nature and the spread of disease. These are:

  • the House Mouse
  • the Black rat
  • the Brown rat
