Snakehead eradication begins in Crofton

Apparently it's a tourist attraction still. And, of course, there's merchandise. I want a Snakehead Eradication T-shirt.

State officials say the chemical cocktail of diquat dibromide and glyphosate will kill all the oxygen-producing vegetation and suffocate a large percentage of the fish, including snakeheads. But because snakeheads have a primitive lung that allows them to breathe out of water, biologists will return after about a week to apply the fish poison rotenone to ensure eradication.

A week? Aren't they just giving the snakeheads a chance to make a slither for it?
