Everything you need to know about getting your order.

When will my order be dispatched?

Orders placed Monday to Thursday are packed and dispatched the same week from our farm in Yoxall, Staffordshire. Orders placed Friday to Sunday are dispatched the following Monday or Tuesday.

You will receive an email notification when your order has been dispatched, including any tracking information if applicable.

How long does delivery take?

Standard delivery takes 1–2 business days after dispatch across most mainland UK addresses. We use a tracked 24/48-hour courier service to ensure your order arrives quickly — this is especially important for live Calci Worms.

Do you deliver to all UK addresses?

We deliver to all mainland UK addresses. For remote areas including the Scottish Highlands, Scottish islands, Northern Ireland, Isle of Man and Channel Islands, delivery times may be longer and additional charges may apply.

If you’re unsure whether we can deliver to your address, email us at hello@syntects.co.uk before ordering.

What is the delivery charge?

Free delivery on all orders over £20. For orders under £20, a standard delivery charge applies — the exact amount is calculated at checkout before you complete your order.

Subscription orders include free delivery regardless of order size.

How are live Calci Worms packaged?

Your Calci Worms arrive in our easy-pour ventilated Bag, packed with a small amount of substrate. The bag is designed to maintain airflow during transit while keeping the larvae contained. Do not seal the bag airtight when storing at home.

What if my Calci Worms arrive inactive?

Larvae can go into a temporary torpor during cold transit — this is normal and does not mean they are dead. If your worms arrive sluggish or still:

• Move them to a warmer spot (15–20°C) for 15–20 minutes
• Most will revive and become active quickly once warm
• Avoid placing them in direct sunlight or temperatures above 30°C

If a significant proportion have arrived dead after warming, email us at hello@syntects.co.uk with your order number and a photo. We will replace or refund.

How long do they stay alive after delivery?

Stored correctly, your Calci Worms will remain lively for 7–10 days after arrival. Keep them cool (10–15°C), ventilated and out of direct sunlight. A garage, shed or cool kitchen shelf is ideal. Do not refrigerate or freeze.

Can I return live Calci Worms?

Due to the nature of live animals, we are unable to accept returns of live Calci Worms. However, if there is a problem with your order — larvae arriving dead, incorrect product, damaged packaging — we will always put it right. Email us within 48 hours of delivery at hello@syntects.co.uk with your order number and a photo.
