Several species of grasshoppers and crickets are considered endangered in Australia, including the key's matchstick grasshopper and the Schayer's grasshopper. While in New Zealand, the native robust grasshopper is under threat of extinction. These species are protected because they are an important food source for birds and reptiles and their decline could affect entire ecosystems.

If you find them in your garden and they aren't causing any issues, leave them be. You can discourage them by protecting plants with mesh screens or a 'trap crop' – a border of tall grass that will deter them from reaching your harvest. Neem oil is also thought to be an effective natural grasshopper deterrent.

For any infestations, you should consult a professional pest control company with the correct certifications.
