Was gifted a lightly used Keurig machine. Partner started noticing little roaches everywhere in the kitchen. She was halfway through a cup of coffee when she opened the water reservoir and spotted a few floating in the water. I opened the machine and the machine was full of them.
Roaches can lay up to 32 eggs/week, and I think a roach mom had at least one good week in the Keurig.
Friend had said he didn't want it because it was attracting roaches. He claims to not have known it was carrying them.
