Add Insulated Shipper to allow storage of eggs!
Silkworm eggs are a great alternative to purchasing silkworms. You can grow them to the size you need and then feed them to your pet! Silkworm eggs will be shipped loose in glassine envelopes or glued on a petri dish. This prevents static electricity from throwing your eggs everywhere when you open the container. This also means that the eggs will hatch within 5-10 days.
If you plan to refrigerate eggs to obtain prolonged hatching, purchasing an insulated shipper is required. Ambient temperatures during shipping of around room temperature are enough to trigger development in eggs and they cannot be refrigerated!.
