Arcadia Garden Products Worm Nerd 8 in. Stainless Steel Worm Compost and Garden Soil Thermometer

Worm nerd's temperature meter is a great tool to have when maintaining your worm bin. Ensuring your worms are living in the best possible conditions results in happy, active worms - more eating, more breeding and more castings. Designed specifically for measuring temperature within worm compost bins, the easy-to-read dial includes 4 color-coded temperature zones, ranging from 0° to 140° F (minus 17° to 60° C). Each zone clearly indicates if the bin is too cold, too warm or just right. Keeping the dial's needle within the "happy" zone means your worms are in the ideal temperature range for thriving.
