In the original series of Battlestar Galactica, in the pilot episodes, there was a non-human, alien race called the Ovions. The Ovion were bug like creatures that when they captured their food, they would put them in a chamber and block them in with a honey like substance. The Cylons used them to hold the humans but it didn't work out and soon the Colonials discovered what was happening and made a run for it. The creatures lived underground. There was no equivalent in the new series, it was purely human vs. Cylon.
