Redlands Coast has unique coastal and freshwater environments that provide ideal breeding conditions for mosquitoes. In addition to being a nuisance, some mosquito species can also transmit diseases such as Ross River or Barmah Forest viruses to the community. For this reason, Council’s Mosquito Management Program targets the mosquitoes that are capable of transmitting these diseases.
The Mosquito Management Plan 2017-2024 provides a snapshot of the current status of the Mosquito Management Program and identifies strategies and potential opportunities for future planning.
Redland City Council's role in mosquito management
Redland City Council is committed to delivering a year-round, best practice mosquito management program that is safe for the environment and for residents, to manage mosquito numbers in Redlands Coast.
Council's Mosquito Management Program involves regular monitoring of known mosquito breeding sites across the Redlands, including coastal and wetland habitats. Treatments are conducted at these sites if breeding is identified, with additional surveys and treatments conducted in response to tidal inundation or rainfall events.
As part of Council’s surveillance program, regular light trapping for adult mosquitoes is also undertaken throughout the Redlands. This allows Council to monitor adult mosquito numbers and determine the type of mosquito species impacting certain areas, so treatments can be targeted accordingly.
Council conducts regular ground and aerial treatments for mosquitoes. These treatments target the newly hatched larvae (wrigglers) of mosquitoes before they can fly, as this is the most effective form of treatment. The diagram shows the optimal time to treat mosquitoes:
Council's Pest Management Team will continue to monitor mosquito breeding sites over the winter season and treat these areas as needed. Treatments will be predominantly by ground application given the low numbers anticipated, however, the chemicals used will remain the same.
Under Council's Marine Park Permit, two chemicals are used for mosquito treatments. These are (S)-Methoprene, an insect growth regulator and Bacillus Thuringiensis subspecies Israelensis (Bti), a bacterial agent that kills mosquito larvae via ingestion. These chemicals are safe to use, environmentally friendly and only target mosquito larvae.

Ground treatments are conducted, in addition to aerial treatments, over the entire Redland City. Ground treatments are conducted in areas that have limited access or heavy vegetation cover and are not able to be treated via helicopter, such as Wellington Point. Other ground treatment sites include Redland City freshwater and inland suburbs such as Mount Cotton. Freshwater sites are surveyed and treated as needed with registered products which are safe to use and only target mosquito larvae.

While Council undertakes a year-round Mosquito Management Program, during peak mosquito breeding season (November to April) additional personal protective measures should be taken.
You can protect yourself from mosquitoes by covering up, wearing light-coloured, long, loose-fitting clothing and using insect repellent. If regular insect repellent is not preferred, natural alternatives may be available depending on your local pharmacy or convenience store.
If mosquitoes are a problem in your area:
- avoid going outdoors during dawn and dusk unless covering up and using insect repellent
- maintain fly screens on windows and doors in your home
- treat fly screens with a UV stable insecticide
- use mosquito coils or plug-in insecticide burners
- ensure yards are clean and tidy, remove excessive vegetation and regularly empty pooled water from pot plant bases, containers and tarps
- contact your local pest technician for advice on barrier treatments and whether these are suitable for your home.
Reduce mosquito breeding
While treatments are effective, it's impossible to find or treat all breeding locations as mosquitoes are capable of breeding in small pools of water, such as bird baths and pot plant bases.
To reduce mosquitoes on and around your property, empty out unnecessary water where mosquitoes might breed and ensure rainwater tank screens are in good condition. Common breeding areas can include fallen palm fronds, boats, unchlorinated swimming pools, bird baths, tarps and old tyres.
Projects & research
Council is an active member of the Mosquito Arbovirus Research Committee (MARC). The committee is made up of councils across south-east Queensland, Queensland Health and QIMR Berghofer. MARC also has a dedicated scientist who works with local councils on mosquito research and the latest technologies, to better improve mosquito treatments, surveillance and arising mosquito issues of the future.
Please view a copy of Redland City Council's Mosquito Management Action Plan 2019 - 2024 for further project and research information.
The Queensland Government’s Metro South Health Unit has another round of the Zika Mozzie Seeker project. The mosquito monitoring project involves community participation in setting up backyard mosquito egg traps to collect mosquito eggs for DNA testing. For further information on the Zika Mozzie Seeker project or to register your interest please view the Metro South Health Zika Mozzie Seeker web page.
School education program
Interested in learning more about mosquitoes? Council’s Pest Management Team is now taking bookings for our “mossie talks” on mosquitoes for school-aged children. These sessions run for approximately one hour and are delivered at your school/centre, however they do require a minimum of 10 participants and maximum of 30 per session.
Students will learn all about mosquitoes on Redlands Coast and our Mosquito Management Program, and take part in interactive activities, such as Mossies under the Microscope.
Sessions are limited and subject to availability. To book now, complete the “Environmental Education Booking Form” and under “Select the session you would like covered” and select “Other” followed by "Mossie Talk" prior to submitting the form.
