Mosquitoes

Mosquitoes are a normal part of living in the tropics, but uncontrolled mosquito breeding can affect comfort, lifestyle and public health.

Hinchinbrook Shire Council undertakes mosquito management activities across the Shire, however preventing mosquito breeding is a shared responsibility between Council and the community. 

This page explains how mosquitoes breed, what residents can do to reduce mosquito numbers, and how to protect yourself and your family. 

A day in the life of a mosquito

Mosquitoes need water to breed. 

Female mosquitoes lay eggs: 

  • Directly in water, or 

  • On the sides of containers that may later fill with water 

Some mosquito eggs can survive in dry conditions for several months.

Once exposed to water, the eggs hatch. 

The mosquito life cycle includes: 

  • Larvae (wrigglers), which feed on organic matter in water 

  • Pupae, the stage before becoming an adult 

After several days, the adult mosquito emerges and flies away. 

The life cycle can take anywhere from four days to one month, depending on species and temperature.

How far do mosquitoes travel?

Most mosquitoes travel less than 2km from where they hatch. 

However, some species can travel much further — up to 50 kilometres — when assisted by favourable wind conditions. 

This is why local breeding sites around homes and neighbourhoods play a major role in mosquito numbers. 

Preventing mosquito breeding at home

While Council undertakes mosquito control programs, the most effective protection comes from actions taken by residents. 

You can reduce mosquito breeding by removing or managing items that hold water, such as: 

  • Plant pots and bases 

  • Buckets, wheelbarrows and garden tools 

  • Tarps and plastic sheeting 

  • Tyres 

  • Any unused containers 

Ensure there is no pooling water in your yard. Blocked gutters are a common breeding site when leaves prevent water from draining properly. 

Uneven ground that allows water to pool should be reshaped or drained where possible.

Water, tanks, ponds and dams

Rainwater tanks 

If you have a rainwater tank: 

  • Check regularly that screens and meshes are intact 

  • Mesh openings must be less than 1mm 

Ponds and dams 

If you have a pond or dam on your property: 

  • Stock it with fish that feed on mosquito larvae 

Bird baths and pet bowls

  • Refresh bird bath and pet bowl water regularly 

  • Avoid allowing water to stand for long periods 

  • NOMOZ® pellets prevent mosquito larvae from developing into adult mosquitoes 

  • When used as directed, NOMOZ® pellets do not harm birds, pets or other animals 

Low‑cost NOMOZ® mosquito larvicide pellets are available from Council’s Main Office, 25 Lannercost Street, Ingham. 

Legal responsibilities

Under the Public Health Regulation 2005, property owners and occupiers must take reasonable steps to ensure that water or other liquids on their property do not become a breeding ground for mosquitoes. 

Managing standing water helps reduce mosquito numbers and protects public health across the community. 

Where mosquito breeding is not addressed, Council may take compliance action in accordance with legislation. 

Personal protection

You can reduce mosquito bites by: 

  • Using personal insect repellents 

  • Wearing long‑sleeved, tightly woven clothing 

  • Avoiding outdoor activity at dawn and dusk, when mosquitoes are most active 

Deterrents around the home

In outdoor or indoor seating areas you can: 

  • Use mosquito coils or citronella candles 

  • Use plug‑in chemical dispersers 

Mosquitoes struggle to fly in moving air.

Using: 

  • Ceiling fans 

  • Pedestal or plug‑in fans 

can help deter them, especially when airflow is directed under tables and seating areas. 

Ensure fly screens on windows and doors are fitted and in good condition. 

Mosquito‑borne diseases

Mosquitoes are not just a nuisance — some species can spread disease to humans and animals. 

Only female mosquitoes feed on blood, which is required for egg production. Male mosquitoes do not bite. 

Of the 300+ mosquito species in Australia, only a small number transmit disease. 

Common mosquito‑borne illnesses include: 

Ross River Virus 

Symptoms may include: 

  • Flu‑like illness 

  • Muscle and joint pain 

  • Fever, chills and headache 

  • Fatigue 

  • Sometimes a rash 

Barmah Forest Virus 

Some people show no symptoms. Others experience: 

  • Similar symptoms to Ross River Virus 

  • Muscle and joint pain 

  • Fatigue and fever 

Dengue Fever  

Dengue is not endemic to Australia and occurs when infected travellers introduce the virus. 

Symptoms may include: 

  • Severe headache and pain behind the eyes 

  • Muscle and joint pain 

  • Fever 

  • Nausea, vomiting or diarrhoea 

  • Skin rash 

  • Prolonged fatigue
