Mosquito management at temporary events

Warmer weather & high rainfall make perfect conditions for a big mosquito season.

Warmer weather & high rainfall make perfect conditions for a big mosquito season.

Mosquitoes can spread viruses such Japanese encephalitis virus (JEV), Barmah Forest virus, Murray Valley encephalitis and Ross River virus. The best protection measures against mosquitoes and their diseases is to avoid mosquito bites.

This season we’re encouraging event organisers to be proactive

Prior to the Event

  • Where practical, consider keeping events indoors
  • If indoors, close doors and windows or install fly screens to keep mosquitoes out
  • Consider the timing of the event if outdoors. Avoid peak mosquito biting hours i.e. around dawn and dusk
  • Consider locations away from water bodies or dense natural vegetation such as lakes, lagoons and wetlands
  • In your messaging and advertising for your event, make sure your patrons are aware of precautionary measures to be taken against mosquito bites such as:
    • Wear light, loose-fitting long-sleeved shirts, long pants and covered footwear with socks, particularly at dawn and dusk when mosquitoes are most active
    • Carrying a supply of mosquito repellent to reapply on exposed skin
    • Keeping mosquitoes out when camping. Encourage patrons to bring mosquito nets and screens to prevent entry of mosquitoes in tents
    • Mosquitoes breed in stagnant water. Check outdoor areas at the event location to identify potential breeding habitats such as long grass or water holding containers. Eliminate all potential breeding habitats around the event location

During the Event

  • Display posters or distribute flyers to increase mosquito awareness
  • Ensure appropriate signage is in place (contact Council for signage)
  • Where possible, supply repellents
  • Ensure patrons are covering up while outside
  • Through public reminders; regularly encourage patrons to carry, apply and reapply repellent to exposed skin. Mosquitoes can find and feed on patches of uncovered skin. Repellent containing DEET, picaridin or oil of lemon eucalyptus should be used on any areas of exposed skin and reapplied regularly. Follow the instructions on the product label when applying repellent
  • Reapply repellent after swimming or any water related activities
  • If camping, encourage patrons to use mosquito nets around beds and keep entry points in tents closed or screened

Japanese encephalitis - Get vaccinated

JEV spreads to people from infected mosquitoes. The vaccine is proven to be safe and effective for anyone over the age of 2 months old. Residents are eligible for a free JEV vaccine if they are aged 2 months and older AND:

  • spend significant time outdoors (four hours per day), for unavoidable work, recreation, education, or other essential activities, OR
  • are living in temporary or flood damaged accommodation (e.g. camps, tents, dwellings exposed to the external environment) that place them at increased risk of exposure to mosquitoes, OR
  • are engaged in prolonged outdoor recovery efforts (clean up) of stagnant waters following floods.

Your GP can provide further information and advice to those who may not be eligible for the free vaccine but still wish to be vaccinated.

Risk Matrix

Event should be assessed against the criteria in the matrix.

If ALL criteria are in the low-risk column then the event can be considered low risk. If ANY of criteria are in the high-risk column the event must be considered high-risk. Events that do not meet all low-risk criteria, and do not meet any high-risk criteria will be considered moderate risk.

Low risk events do not require vector control activities but will require communication and messaging about personal protective measures.

Moderate and high-risk events require further risk assessment and consideration of vector control activities in addition to personal protective measures.
