Pest Invaders competition by QuestaGame: learn, play, have fun and help protect your local environment.

The Pest Invaders competition for schools by QuestaGame is a fun and educational way to learn about the world of insects and their impact on our environment. Learn about the fascinating lives of bugs and help track down invasive species in your area.

Join the competition and become a part of a unique community that shares your passion for nature!

The competition is organised in collaboration with the Queensland Department of Agriculture and Fisheries.

Why insects are essential to our ecosystem:

  • Biodiversity - Insects play a vital role in our ecosystems by pollinating plants and flowers, which helps to maintain biodiversity. Without insects, many plant species and animals would not survive.

  • Natural pest control - Insects also act as natural pest control by preying on other insects that can cause damage to crops and other plants. This helps to reduce the need for harmful pesticides.


The invasive species problem


Invasive species are non-native organisms that have been introduced to a particular ecosystem and cause damage to the environment, economy, or human health. Insects like the Asian longhorned beetle and the spotted lanternfly are examples of invasive species that are causing serious damage in the US.

Citizen scientists play a crucial role in helping to track the spread of invasive species and monitoring human activity's impact on insect populations.

Participation in the competition. 

To participate in the Pest Invaders competition, simply download the QuestaGame app and follow the prompts. The game is self-explanatory. Join a school team and start searching for insects in your local area. Every time you find an invasive species, take a photo and submit it to the QG. Your findings will be added to a global database, and you can earn rewards for your efforts.

Rack up the most points by the end of the competition, and you could win some great prizes and earn bragging rights as the Pest Invaders champion!

Last year's competition winner, along with their family, received a free helicopter tour of some of the Great Barrier Reef. Congratulations to Blayd on winning the competition and to the sponsors and the Queensland Department of Agriculture and Fishers for organising the prize! The family seemed to have an amazing trip. To quote their email:

Spectacular! Amazing! Breathtaking! Blayd and his family would like to thank everyone involved in the organisation of such a magnificent Questagame prize. Blayd and his family recently experienced a Scenic Helicopter Flight over Green Island, Yarrabah, False Cape, Arlington Reef, and Vlasoff Sand Cay from Cairns. Our family got to see a family of Dugongs, turtles, a pod of dolphins, and the spectacular reef around Green Island. Our family would like to say a huge thank you for this amazing opportunity.

The benefits of participating in the Pest Invaders competition:

  • Learn about the world of insects. While participating in the competition you can discover new species and expand your knowledge of insect biology and behaviour.

  • Contribute to scientific research. You not only learn about biodiversity but your findings will be used by researchers to study insect ecosystems and develop conservation strategies. 

  • And finally, get rewards for your efforts. By submitting and identifying observations you earn gold, and depending on the current edition you can also win some awesome prizes! But most importantly you help protect our planet. 

Pest Invaders 2023 runs between 23 January and 26 June. There is still time to join the fun and compete with school teams worldwide. For more information visit https://www.pestinvaders.org/ or contact Gosia at gosia@earthgaurdians.life
