Catching Hairy Crabs
 

I have at least two hairy crabs I would like to catch. Have tried the leaning glass with bait for over a week but no luck. Any other successful methods?

They only come out after dark and are much too quick to grab.

if you can take the rock out and put it in a container, they may leave looking for water,
or you can spray soda water into the holes and flush them out.

I had to pull out the rock and get the little dirt bag with tweezers and a turkey baster. Took awhile but I got it
