I'd like an answer to that too! I have used every bait on the market, and it just seems to attract more of them. To get them out of your pots you can set the pot in a larger bowl and slowly fill the bowl with water. If you give them a bridge, they will pack up their eggs and go. Now if I could just figure out how to keep them from returning....
It might be worth a try to use the granules on an orchid you wouldn't mind loosing, too much. If they set up housekeeping in a pot, they farm a fungus to eat that will completely block the drainage holes. I've lost a couple of Plants (not orchids) that way.
