Project: Cricket Dispenser

Materials

I have used both PVC pipe of various diameters with threaded caps, and sections of bamboo (which present a more naturalistic appearance). The PVC is easier to keep clean. Black seems to be less conspicuous in the exhibit than white, although if clear ever becomes available it would be worth a try.

Instructions

The dispenser can be about 1.5' long, and between 2-3" in diameter. You can cut the sections you need with a Saws-All (electric hacksaw). Remember to clamp very tightly prior to cutting. If you are using PVC, sometimes the plumbing supply will cut the pieces for you and thread the ends for the caps. If you are using bamboo, use the natural internal divisions as your end caps. Cut at least 1/2" beyond each division. You will need fairly mature bamboo to get the diameter you require; we were fortunate to have 2.5" diameter available at the LA Zoo.

The smaller you make your holes, the longer it will take all the crickets to creep out which keeps the dispenser interesting for longer. If the animal would enjoy reaching inside, make your holes to allow this if you like. 1/4-3/8" is about right for your smallest diameter, depending on the size of your crickets. Clamp the dispenser tightly before you begin drilling. Even 2 holes is plenty.

Cautions: If you think the animal would try to use the dispenser as a weapon, you can chain it to the exhibit wall or perching. Use an eye hook through one end. The dispenser will need cleaning out or it will produce an awful odor since all crickets do not escape.
