multi tier worm bins are real bad for brand newie worm wranglers. The trouble is they seem like simplicity itself. open lid and throw kitchen scraps which are 70% water in top tray and sprinkle with water. Over time these kitchen scraps 'decompose' and the worms eat upwards on the food, fungi, organisisms all muching away at these foods. The water and moisture from the kitchen scraps follow gravity to the bottom of the bin into the sump. So this bottom area tends to mainly be moist and smelly since new worm wranglers tend to not empty the leachate (which is toxic and poisonous) off enough, so the worms tend to dislike this bottom area since it has yucky stagnant water pooling there; its basically a swamp since it also contains worm castings. Thus new worm wranglers often drain off this foul smelling soup and flush the system with more water, but by 'overwatering' now they are compacting the upper layers with water molecules. this is because water acyaully is very heavy and it clings to itself, so the overwatering tends to compress the food bedding layers and the water clings to itself and displaces oxygen. So now we get anerobic decomposition and instead of aerobic methane that quickly disapates off in a well balanced oxygenated worm bin we get a compressed mass of food that slows down its decomposition due to lack of oxygen. Now we get ammonia gas and this gas kills worms real dead, so the worms must run away (into the bottom sump) or do a worm run and leave the bin entirely to avoid being gassed to death. So, to dry, to wet? the newbie worm wrangler tends to lighten up on how much water they add, so gravity tends to pull down moisture into the bottom layers and water sump. So now the upper layers of newer food tend to dry out more and worms breathe through their WET MOIST skin so they tend to move to where the water is (into the sump) luckily. AS long as they have a ladder to reclimb back up to the bedding layers instead of drwoning in the sump. Remember they need moisture to breathe so they dehydatrate if they stay up top. If it rains then they worm run away to the refreshing outside rain and die from sunlight or lawn fertilizer or whatever. So this is why (especially) with a sudden unplanned for run of hot weather that evaporates or transpirates your top layers of moisuture away your worms flee to the bottom sump layer for the life giving water. Remember without water worms are dead, dry bedding to a worm is the same as you crawling over broken glass or sandpaper without protection; it would not be nice so do not 'neglect' your worms. These factors and others are why multi tier worm farms are not the greatest for newbie worm wranglers, but remember worms are very resilient and people learn if they lose or hurt their babies (worms), so over time humans get better at 'listening' to what worms "like". Generally worms like being left alone to do their thing and mainly new worm wranglers try to hard to 'help' the worms with to much food or water but we humans usually get better over time, but of course you have to take note of the weather since worms cannot learn to drink from a tap; how could they turn it on ? ;)

Hi Kath - Thank you for replying. Evidently they are New Zealand mud snails which are harmless to the worms except that they are extremely invasive and will reproduce my the thousand within a week or two. One of the people on another forum had them in her aquarium and she had to clean out her aquarium twice with scalding hot water to get rid of them. She had to boil her rocks, etc. as well. So I have to remove all of my worms and cocoons from the bedding and rinse them off with warm water and then place them in fresh new bedding after thoroughly cleaning my bin and trays with super hot water. The only best way to kill the snails is to drop them and their eggs in salt water. So I figure after I remove my worms and eggs I'll dump all of the bedding and compost into a bucket of salt water and then dispose of it. I hope my worms are just slow like yours. :P Maybe it's just the type I have - I have Indian Blues.

A few weeks back I lost all my worms in my worm bin, which really stumped me because I had a flourishing and healthy worm bin that was thriving with hundreds of red wigglers in various stages of their lifecycle. I took a bit of a hiatus in feeding them as I was trying to maintain the level of mites I had in my bin (I basically wanted to keep it balanced). To be honest I don't know what might have happened, has anyone experience the same phenomenon? I don't think it was the mites as from most of the articles I have read they don't affect the worms and the population of them wasn't too out of control. Also when I looked through the bin to find any evidence of the worms there was still small amounts of food in the bin! Please help me on the famous worm disappearing act.

I see what you mean, perhaps the one on the right has more aged flowers, but what I see is a whole lot of buds coming up, almost 10-15 at a time per plant, then just a few flowers bloom and the rest just shrivel or stick together like in the left photo. All I could do is take daily photos to confirm what's happening but some are almost devoid of full flowers, but the buds are there.
