FAQ

Which worms are best for a small kitchen bin?
Red wigglers are typically ideal for small, indoor bins due to their compact size and efficient processing.
Do all worms burrow to the same depth?
No. Different species tunnel at different depths; diverse mixes can enhance aeration and nutrient access.
Can worms survive in all climates?
Most red wigglers tolerate a broad range of temperatures, but extreme heat or cold can slow activity. Use insulated or shaded bins as needed.
Is there a risk of odors?
Yes, if bins are too wet or poorly aerated. Maintain moisture similar to a wrung-out sponge and ensure proper drainage.
Should I supplement with worm food?
Yes. Add gradually, balancing green and brown matter to avoid excessive moisture and odors while sustaining worm activity.
