How to Make a Storage Box for Nightcrawlers

How to Make a Storage Box for Nightcrawlers
When you grow tired of having to go to the bait store, or dig up a fresh supply of nightcrawlers to fish with, perhaps it is time to make your own nightcrawler storage box. Making a storage box and keeping your own worms lets you by-pass the bait store step, and head out for more time on the water going for the big ones. Making a nightcrawler storage box, for home use, is a straightforward procedure.


Difficulty: Moderate

Things You’ll Need:
  • Power drill
  • Small screws
  • Three pieces of plywood cut to 2- by 3-foot
  • Two pieces of plywood cut to 2- by 2-foot
  • Caulk gun with caulk
  • 2 bags of peat moss, available at home and garden stores
  • 5 lbs. loose gravel
  • 2 cups old coffee grounds
  • Newspaper soaked in water
Step 1
Set out the 2- by 3-foot pieces of plywood along with the 2- by 2-foot plywood pieces, so the four pieces make a rectangle. Arrange the sections so the 2 by 2 sections are sandwiched in between the 2 by 3 sections.
Step 2
Screw one end of the rectangle together using the power drill and four screws, two each at the corners of the rectangle end. Repeat this with the other end of the rectangle, securing the box into shape. Check each corner for loose screws or slippage. Reinforce with additional screws if necessary.
Step 3
Drill one section of 2- by 3-foot plywood to the top of the box, so you have a rectangular box, with one end remaining open. Use two screws at each corner to make the box.
Step 4
Turn the box, upside down, with the open end facing down. Hold the box up and into the light, so you can check for any large gaps or holes where worms might wriggle out. Use the caulk gun to fill these gaps, if some are present.
Step 5
Turn the box back over and place in a dark, cool location. Put the gravel in the bottom of the box, the closed end, on top of the plywood. Pour the peat moss on top of the gravel. Having the gravel at the bottom aerates the mixture, giving the worms oxygen.
Step 6
Mix the coffee grounds into the soil and peat moss. Mix thoroughly. The coffee grounds add acidity and provide a healthy pH balance for the soil and worms. Add your worms to the box. Add moist coffee grounds when the soil begins to dry out. If too dry, soak newspaper in water and place on the sides of the box to allow seepage.

Tips & Warnings

Do not line the inside of the box with plastic bags or liners. This restricts air flow and may kill your worm supply.
