Keeping Mealworms for longer periods.
The mealworms will arrive with enough food for at least a week and probably much longer but if you need to keep them long term then they will need extra feed and a source of moisture. The source of moisture should be added on arrival and should be a small piece of Banana skin about a couple of inches long or segment of apple or potato, this should be put into the container and the lid left off make sure anything added does not give the mealworms a "bridge" to the top edge or they will use it and be gone! This source of moisture should be removed (if there is any left) and replaced every couple of days, do not allow it to go mouldy and contaminate the dry food matter.
As the mealworms feed the original food will become very fine and sand-like it should be sieved off and replaced with new food, this can be bran, porridge oats or similar dried cereal. The container should be kept in a cool place but not a refrigerator.

Dried Mealworms.
We are often asked if we supply dried mealworms, sorry but we don't, there are very good reasons for this, despite all the claims made about being as nutritionally equal to live mealworms, they are not, also a very important factor is the moisture content, live Mealworms do not have high levels of moisture compared to say earthorms (80%) when they are dried they have no moisture at all and when fed by the parent birds to chicks can actually cause de-hydration as the dried mealworms absorb the moisture from the chick, this is the opinion of zoo's that specialise in bird care.
