Don’t release classroom ‘pets’ into the wild

INVASIVE SPECIES -- As the school year comes to a close, the Washington State Invasive Species Council is asking teachers and parents not to release classroom pets, insects, fish or aquarium plants into the wild.

“Most of the classroom animals released into the wild will not survive," said Justin Bush, executive coordinator of the Invasive Species Council.

What seems like a humane action often leads to suffering in the end for the animal, he said, not to mention the bad things it could mean for native wildlife.

Some common invasive species that have damaged Washington’s environment and economy – rusty crayfish, bullfrogs and Eurasian watermilfoil – started as classroom pets and aquarium plants. Eurasian watermilfoil alone is known to infest more than 30 counties in Washington.

In the United States, invasive species cost more than $137 billion annually, through crop damage, fisheries reduction, forest health impacts and management. Plants, which might survive because they can more easily adapt to their new environment, can grow rapidly, often smothering native, beneficial species.

In many cases, released wildlife can spread diseases to native wildlife and decimate the local populations.

Most non-native classroom pets will not survive in the wild because of predators, the difference in climate and the inability to find food and shelter.

When faced with dealing with classroom plants, insects and animals at the school year’s end, here are some tips to properly dispose of them:

  • Donate unwanted plants and animals to an accredited environmental learning center, aquarium or zoo. You also may contact your local pet store, which might be willing to accept them. Please instruct them to never release them either.
  • Contact a veterinarian or pet retailer for guidance on humane disposal of live animals.
  • Seal all plants in a plastic bag, freeze for at least 24 hours or until frozen solid, and then place them in the trash. Do not compost the material.
  • Flush aquarium water down the toilet. Disinfect aquarium and non-organic materials with a bleach solution of one cup household bleach per gallon of water. Let sit for 10 minutes, then rinse thoroughly.

If you suspect you have an invasive plant, fish, mollusk or crustacean, please report the sighting to the Washington Invasive Species Council using the online form or the WA Invasives smartphone app, available for iOS and Android devices, at www.invasivespecies.wa.gov/report.shtml.

The Invasive Species Council, established by the Legislature in 2006, provides policy level direction, planning and coordination for combating and preventing harmful invasive species throughout the state.
