Lobworms are probably the most difficult, they are very particular about bedding conditions and especially temperatures so extra care has to be taken.
The bedding they are sent out in is a careful mix of moss peat, cardboard, cardboard dust and clay dust and It will be necessary to bulk this up when the worms have arrived, materials that can be used are wet paper, cardboard, moss peat and fresh moss as raked from the lawn (make sure no sprays have been used recently) and the moss that grows on logs plus any dead leaves that can be found, any or all of these should be put into larger container or breathable bag and the lobworms added, this really does need to be kept cool and on this occasion we would recommend the use of a fridge set at warmer temperatures, ideally around 6degC, if this is not possible then the coldest shed or garage floor will have to do, many customers stand the container in a bowl of water particularly in the summer and this seems to be quite effective. Containers and bags must be well ventilated but kept closed at all times, even at these lower temperatures Lobworms will continue to feed and the bedding needs to be changed as necessary. The usual rules of taking only what you need for fishing and trying to keep temperatures constant apply as does the rule of not adding returned worms back to the original stock, especially so with Lobworms.
This really is not much different to the above short term, except with the exception of bigger containers and more bedding, in this case we would strongly recommend considering a Worm Keeper. Lobworms should not be fed on green kitchen waste or the mashed potato routine, it can cause them problems. If you are not experienced in keeping Lobworms we would suggest starting with a smaller quantity to try.
