Pest Management

 Rats

The presence of rats may be detected by 'droppings', 'rat runs', 'eaten foods' or damage to food containers.

How to Remove Rats from Your Property

Trapping and poisoning will kill rats on your premises, but this is only a temporary measure as rats will return if favourable conditions for existence persist. For complete extermination and protection against reinfestation, rats must be deprived of food and shelter.

How to Deny Rats Food

  • Place all food scraps in a container with a close fitting lid. If compost bins are used, keep the base of the bin clear of any vegetation and don't throw meat or dog faeces into the compost bin.
  • Keep fowl yards clear of all waste products.
  • Keep poultry and animal food in metal bins with tight fitting lids.
  • Where there are fruit and nut trees, regularly clean up any fallen fruit or nuts.

 European Wasps

European WaspThe European wasp is most easily identifiable by:

  • Its black and yellow body;
  • Its yellow legs; and
  • Triangular markings on the abdomen.

While the European wasp is the same size as the bee (10 - 15mm), it is less hairy and folds it's wings back at rest. Unlike the bee, a European wasp can sting multiple times. If left undisturbed the European wasp is not aggressive to humans or other animals.

The following tips should be followed to prevent European wasps being attracted to your property:

  • Do not leave fallen fruit or food scraps lying around your yard
  • Avoid leaving uneaten pet food or dog bones outside;
  • Make sure rubbish bins have tight fitting lids;
  • Keep compost covered at all times;
  • Keep your swimming pool covered when not in use;
  • Cover exposed food at picnics and barbeques;
  • Don't drink out of cans or bottles - use clear containers or a straw.

The following tips should be followed to locate a European wasp nest:

  • Establish the direction the wasps are flying by place a food source (ie meat or pet food) in a visible location;
  • Once the wasp has collected the food, it will fly IN A DIRECT LINE TO THE NEST;
  • A wasp may be scavenging for food up to 500m from the nest;
  • Keep relocating the food sources in the direction of the nest;
  • You may need to work co-operatively with your NEIGHBOURS.

Nests are located where shelter is available. The most common location for nests is UNDERGROUND and nests will be evident by a stream of wasps entering and leaving a hole in the ground. Nests are also found in retaining WALLS, hollows of TREES and wall cavities. The nest is made of grey paper mache type material. Nests constructed of mud are NOT European wasp nests

Once you have located the European wasp nest, contact The City of Charles Sturt during business hours for arrangements to be made for the destruction of the nest on 8408 1111.

 Mosquitoes

As mosquitoes breed in water you can help reduce the number of mosquitoes in your area by removing or treating water storages around your property. Follow these simple steps to prevent mosquitoes breeding around your home.

Control of Mosquito Larvae (Wrigglers)

  • As an interim measure a small quantity of domestic kerosene or paraffin oil (1-2 teaspoons) may be added to the water surface as a larvicide, (the amount will vary depending on the size of the tank) this film will be lost by evaporation or when the tank overflows and should be replaced every 3-4 weeks.

Kerosene may taint the water and should not be added in quantities greater than that suggested. It should not be applied when the water level in the tank is low.

Water:

  • Fix dripping taps
  • Remove other water sources

Hiding Spots:

  • Check and clean surfaces underneath and behind appliances (e.g. toaster, microwave, fridge) regularly
  • Fill cracks and crevices that can provide shelter
