PLEASE CHECK WEATHER IN YOUR AREA - Message us to have your order held for pickup at your local post office if highs are below 55F or above 85F. Our large Superworms average around 1.5-2". We take the extra time to ensure you receive a giant worm. If you are used to other suppliers that sell smaller "large Superworms," we suggest ordering our medium Superworms. Superworms are one of the most active feeder insects out there. We find even the pickiest of eaters love a good Superworm. All of our Superworms are raised on natural food. We do not use growth hormones, chemicals, or other synthetic food products while raising our Superworms.
