Crab traps are available for purchase at many bait and tackle shops near shores where crabs are prevalent. These traps can be expensive, depending on how big they are and what materials they're constructed from. Instead of spending extra money on buying a manufactured crab trap, you should make one from materials that you may have laying around your home. You may not be able to catch as many crabs with the trap, but you can definitely catch a few. Crabs have a problem getting out of tight spaces with steep walls, especially if the walls are slick and made of plastic. This makes a plastic water bottle or bucket a perfect item for making a crab trap.
Obtain a large plastic 5-gallon water bottle. Or use a 5-gallon bucket available at any supermarket.
Cut the bottle or bucket with a saw. Make the cut 10 to 12 inches up from the bottom.
Drill or poke two holes into the bottom of the bucket or bottle. Thread a string or twine through the holes and tie in a loose knot. This is to keep the bait from floating away.
Cut out a piece of plastic to fit over the bottle or bucket. If using a bucket, use the lid. Cut a rectangle 3 inches wide and make the length as long as the lid or piece of plastic without cutting through it. Place the lid onto the bucket or bottle and fasten it in place. You can use string or screws to fasten the lid.
Place bait, such as fish or any type of meat, into the bucket and tie the string over it securely. Find a recess in shallow water---in an area where you know crabs will be---that the bucket will fit into or dig a hole to fit the bucket in. Find a few small rocks to place at the bottom of the bucket to ensure that a current won't pull the bucket out of the hole.
Leave the bottle or bucket in place for a day or two, then come back and check for crabs.
