Berry,

Lived in Florida for seven years. Sprinkle oxalic acid in the dark
places. Under drawers in backs of cabinets etc. They like the aroma.
They walk through it and it clings to their legs and antennae. When
they clean these appendages it gets into their digestive system and
that's all she wrote. Also the young pick it up from the adults and
same thing happens. Also if you find an egg case and don't want to
risk a mob of the critters being released when you try to pull it free,
just paint it over with anything that will seal out oxygen. We used
clear nail polish remover. Wait a week and you can lift it.
