Also put out 10 spear traps and 8 light sticks. With aid of lights dug out 2 but killed a ♀ accidentally. She had 4 emb x 9 mm. 2 mi.

No live ones taken in live traps. Over half of them had been worked around. The thought just comes to me - there is too much air getting in this traps. Will pack them with dirt leading a burrow running through the traps then seal them in the ground to exclude air. Maybe this will cut down on their act of burrowing around as feeling happy with dirt.
