Carolina Cricket/Roach Waterer, plus 1 replacement sponge Weve tried all the alternatives and this works for us! Simply put its a practical solution to keeping your crickets and / or roaches supplied with water. No more smelly potatoes, messy water gels or weekly expenses. The sponge wicks the water up and the crickets or roaches drink off the surface. Crickets dont drown themselves as they would in a water dish. DIRECTIONS: You fill the reservoir up with water, screw on the base and sponge (upside down), then turn the waterer right-side up and wet the sponge THOROUGHLY under the sink faucet. Push the sponge into the trough of the base; making good contact with the holes where the water seeps in. Place the waterer LEVEL in your cricket/roach tub or the water may overflow the lower sides edge. Add some substrate (egg flats) around the waterer to make it easier for the crickets or roaches to get to Waterer usually needs to be refilled or topped off every 3-6 days. Good idea to rinse out the sponge thoroughly and even use some chlorhexidine sprayed on for general hygiene. Waterer measures 8-5/16 tall and 6 diameter. This will fit into a 56 quart or a 106 quart tub; which is what we use to keep our crickets and roaches in. Anything smaller than a 56 quart volume makes it likely that a significant number of your crickets will die prematurely; from smothering each other or from sweating to death by not getting enough ventilation. Sponges typically last 6 to 8 months. Waterer comes with an extra sponge. Additional replacement sponges are available in packs of three.
