If I remember correctly - they did same for Zebra mussels- were never able to eradicate- even after spending untold millions of taxpayer funs.
Zebra mussels aren’t largely a problem anymore. It was eventually discovered certain fish were thriving by eating the mussels.

Yellow perch and smallmouth bass absolutely love zebra mussels. Their populations have exploded, at the expense of the mussel population. It was also discovered that the mussels will not anchor to anything treated with a copper-nickel alloy. The power and water treatment industries have adjusted accordingly and damage from the mussels implanting in pipes and water intakes has largely stopped. Also, as they are filter feeders they have discovered that the zebra mussels in lake Erie have contributed signifigantly to ridding it of pollution. In the lake since the mussels arrived water clarity has gone from 6 inches to 3 feet.

At least the mussels cleaned up the polluted water so clear fish now get sunburn.
