In early December Washington Department of Fish and Wildlife (WDFW) Police received information that a Seattle market was selling live “green crabs”. The Seattle seller had bought the live green crabs from a seller in Massachusetts with the intention of selling them for crab stock and soup. The crabs were destroyed by WDFW Police officers.

The Montana and Washington invasive species councils have joined forces to stop wild pigs from crossing borders. The two councils issued a report with recommendations and best management practices aimed at helping federal, state, provincial and local landowners manage wild pigs in the western United States and Canada. "Wild pig populations are expanding in the western provinces of Canada and in the United States." said Stephanie Criswell, coordinator of the Montana Invasive Species Council. "We are at a unique point in time where we can work together to prevent Canadian wild pigs from spreading across borders into unaffected states like Montana."

In early 2020, the two invasive species councils convened a working group of more than 40 federal, state and Canadian feral swine experts to discuss challenges and opportunities to prevent feral swine along interstate and international borders. Finalized this month, the report includes 22 recommendations that address five strategic areas of feral swine management. Recommendations include standardizing communications to the public, expanding monitoring networks by partnering with non-traditional organizations such as hunting groups, and formalizing notification protocols for reports that will be shared between state and provincial authorities along the international border. The complete report can be found at misc.mt.gov.

A parasitoid wasp that is the natural enemy of a fly known as the spotted-wing drosophila could be a good friend to growers. Washington State University researchers recently confirmed the discovery of the potentially beneficial wasp in the United States for the first time. The drosophila flies cause major damage to several Washington crops, especially sweet cherries and berries. The wasp, which lays its eggs in the flies, could be a means of controlling their spread.

Asian giant hornet is the world's largest species of hornet. In December 2019, WSDA received and verified four reports of Asian giant hornet near Blaine and Bellingham. These are the first-ever sighting in the U.S. Canada had also discovered Asian giant hornet in two locations in British Columbia in the fall of 2019. If it becomes established, this hornet will have serious negative impacts on the environment, economy, and public health of Washington State. If you think you may have spotted an Asian giant hornet, report it to WSDA's Pest Program and, if possible, include a photo.
