If they are real tiny they are probably "sweet ants". they eat sugars and sweets. you can get rid of them by watering the bed a little more. They don't like it wet. put some sweet poison near the bed and they will swarm to it and leave the bed. You real problem is the next set of ants that will be coming. Fire ants! Can you place the legs if any under the bed in a pan or bucket with some oil in it? That way they can't crawl up them to get into the beds. I have seen people place a row of lime around a bed to prevent ants but I don't remember how well it worked. To eliminate maggots you will need to keep flys from getting to the surface of the bed or from the food that you are going to put in it. Old window screens or something.

I hadn't even thought of the fire ants - let me take one little set back at a time :) I like your suggestion about the sweet poison - I'll look for some. The window screen suggestion is good too. I just thought with a top I wouldn't have that problem, but of course I have the holes. Are your beds outside? I am having to mist mine to prevent drying - bet you have the same problem in Atlanta. Thanks for the suggestions.

I'm in central Florida with a big bin outside. My bin has legs so I put each leg in a tray of water to keep the ants from climbing up. Perhaps the oil would be better since with the water you have to watch for mosquitos.

I built my bin out of wood 2' by 4' and made a screen top for it but flys are persistent and can still get in if they really want. The bin is under a roof but will still get some dripping during a heavy rain.

The little white worms you mention (if they are really small) could be what they call pot worms and are normal in worm bins. Make sure to bury food scraps under bedding to help avoid the real fly problem.

I keep a layer of paper or cardboard overtop of the bedding to help keep the bin from drying out too much. I find I don't need to add much water since the food has a high percentage of moisture in it. Remember that the worms only need it as moist as a wrung out sponge and that the lower levels are probably still moist even if the very top of the bedding is dry.

over feeding and over watering are two of the most common problems new worm farms have.

If your bin has legs, can be fitted with some, or lifted onto something with legs you will find keeping ants out much easier. Before I put the legs of my bin in containers of water, nothing I sprinkled around the bin would keep the ants away from more than one day.

I probably am going to have to build a new bin. This one is a large commercial grade plastic bin that was a freebie. Almost a large shallow dumpster with a lid. I don't see how to attach legs. Perhaps I'll use it for a hot compost bin and build a new one for the worms... Nobody warned me before I got into this that I would want MORE bins, MORE worms, BIGGER operation! :)

you can attach legs by just putting the bin on concrete blocks.
