I think you will be OK. I've read people who freeze the vegetables/fruit also to kill insect eggs. Microwaving would do the same and also to heat the vegetables or freeze them will make them softer and thus breakdown more easily for the bacteria and worms to eat and speed things up so you can feed more often.
I think if you get fruit flies it will be one that comes in through an open door and into your house where it will no dought be in your kitchen.
I didn't have worms in the house until today. But I always get a few fruit flies in the summer when I leave out any fruit that is cut up and I am saving the rest for the worms.
Also you want to bury the food and don't let it sit out on top of the worm bin. Bury it 1 or 2" under the soil or bedding. That will help out a lot too.
Put an apple core, rotten banana and slice up carrots or juice them and put these in a slop can or jar with a tight lid and refriderate it or freeze it or just keep it in the jar until you can feed the worms again. They do like rotten stuff. Don't throw away that old slimmy lettus and rotten tomatoe you find months later that is hardly identifiable. Yet that goes in too. Good luck Bill C

Thanks Bill,I never thought about keeping the decomposed goodies in the refg.I can do that.I will use the blender also,starting to get fun again,i just need to order my worms now.So did you move your bin into the kitchen?How long have you been doing this?Again,thank you,just1more

Your welcome. I have just had my worm bin that is in a plastic tub in the house for 24 hours right now. It some how got rain inside and filled with water. I drained it and took all the worms out and put them into another bin I made a month earlier and added new dry bedding to the soaked one and hope to have it recover from the flood. It had many egg capsules and these were my future fishing worms for my boys. I actually bought worms the last fishing trip since I didn't want to use my favorite worms which are the large ones. I bought them from a fishing store in a small plastic can with 25 large redworms in each one. So this bin was started with only 125 worms in it. I had taken out about 300 out of it to move into the other bin. So I am hopeful the eggs will hatch and I will have plenty from here on out. I also have the EF redworms in a wood bin outside next to the plastic one that got water in it, but the wood one is fine even though it has an 1" gap on one side.
So my wife today said, " Get those worms out of my kitchen they stink". I told her that was the trash she smells not the worms and took the trash out. The worms are still here, well actually the eggs. I explained to her it got flooded and the worms are outside except the few I didn't get out, but it was loaded with eggs and I want them to hatch if at all possible. I told her they have to stay inside where it is warm or they will die. She rolled her eyes up and walked out of the room. She gave up on this one. I am hoping they will hatch sooner if they are in warmer temps? But truthfully they do not smell at all. I have a damp cardbaord on top to keep them in the dark at all times and that does have a musty basement smell to it if you put your nose right down into the bin, otherwise it is fine. I think you said you didn't have worms yet? Do you have some new paper and card baord soaked for a day or two and put into your bin. I wished I had done that when I first started out, so it could be really soft and moist for them. Because you can add more paper or drain it if it is too wet before you put the worms in it. Once you have the worms in it, it is harder to make it less wet. Good luck to you! Bill C

Bill,I am going to oder my worms today,and,yes, my worm bed is ready and waiting,as a young boy,my husband lived down south next to a processing gin where they processed soy beans,he said a lot of the beans would fall on the ground and when he wanted to go fishing all he had to do was just scoop up the dirt and he would have hand full's of big fat worms.I don't know what made me get into this,i actually do not like worms,ha ha ha,but i want to do something good for the environment,i read some where that each household has 600 pounds of garbage,if we all did vermicomposting at the end of one year we would have 150 pounds of castings,free fertlizer that is good for the earth and less in the land fill,this is my main reason for getting into this,my girl friends are freeking out with the thought of worms in the kitchen,ha ha,my husband is all for it,he used to own a gun and bait shop, but that is another kind of worm all together as you know.This is nice exchanging ideas with other like minded people.I will let you know how thing progress.Have you collected the castings yet,if so, did you get a pound?How exciting!just1more
