What types of worms do you sell?
We offer composting worms (Eisenia fetida), often known as red wigglers, sold by the pound. These hardy worms thrive in home worm bins and quickly convert organic waste into nutrient-rich castings for your soil.
Can I pick up my order locally?
Please look on our map of locations and see if the location nearest you has in-person pickup service. You may contact the location directly for pick up details.
How do you ship live worms?
We ship live composting worms carefully in breathable bags with moist bedding to keep them healthy during transit. Orders are packed and shipped Monday through Wednesday to prevent weekend delays, and you'll receive tracking information so you know when to expect them.
What are worm castings and how do I use them?
Worm castings are the nutrient-rich compost produced by worms. Mix a handful into your potting soil or sprinkle them around the base of plants as a top dressing. Castings improve soil structure and provide a slow-release fertilizer for healthy growth.
Do you offer bulk discounts or co-op pricing?
Yes! As a cooperative, we offer tiered discounts when you buy multiple pounds of worms or large quantities of castings and tea. Members benefit from special pricing and can participate in group orders to save even more.
Yes, we offer discounts on bulk orders. Please contact our customer service team for more information.
What if my worms arrive damaged or don't survive transit?
We guarantee live arrival on our worms. If your worms don't arrive healthy or don't survive the journey, please contact us within 24 hours with photos and we'll send a replacement or refund your purchase.
How much worm tea should I use?
Dilute one part worm tea to ten parts water and use the solution to water plants every 1–2 weeks or as a foliar spray.
Dilute worm tea before applying: mix one part worm tea with ten parts water. Water your plants with this solution every 1‑2 weeks or use it as a foliar spray for a gentle nutrient boost.
