Relocate or recycle the crab as you see fit.
When you want
to put a trap in place to catch a ghost crab remember that it
will only be successful if there is a crab in the hole. A
good indication of this is when the sand around the hole is damp and darker
in color. It's pointless to put a trap over a hole that is surrounded by dry
The crab won't enter
the trap until he needs to leave his hole. That
happens at night when he needs to go to the sea. That's why
you must check the trap the next morning to see if it has been successful.
Ghost crabs are good
climbers but they can't go straight up. Place
the trap in the tunnel following the angle of the tunnel.
The tunnel never goes straight down.
These crabs aren't
too bright but they aren't stoopid either. If you don't firmly
imbed the center tube in the hole and build the sand up around the trap
then the crab will simply push it out of the way when exiting the hole.
