Suitable Climate and Temperature

Redworms (Eisenia foetida, Eisenia andrei, and Lumbricus rubellus), the worms most commonly used in vermicomposting, feed most quickly in 15-25C (59-77F) degree temperature. They can survive at temperatures as low as 10C (50F), but temperatures above 30C (86F) may be harmful to them. This means that indoor vermicomposting can be practiced in all climates, except tropical. However, other worm species, e.g. Perionyx excavatus, are suitable to be used in warmer climates. If vermicomposting bin is stored outside, it should be sheltered from direct sunlight and protected from frost in winter. The temperature in large-scale vermicomposting bins (which may have high heat-retention properties) should be monitored regularly, since feeding material can compost, consequently heating up the bins and killing the worms.
