Has anyone found this helps harbor or bring in fungus gnats?

I only ask because 4 or 5 years ago I decided to start keeping all my coffee grounds to use them on my garden and flower beds. To save them, I used a 13 gallon plastic trash container placed under my sink, and each day threw in the coffee grounds. After a few weeks I noticed gnats. Then I started some seeds in potting mix, and they wiped out some of my seedlings by their larvae eating off the roots. Then I tried to figure out what the nasty thing was, and after finding out, it seemed to have started with the coffee grounds.

Secondly, I really want to do this, but can the containers even be smaller? I have very little space in house at all. Two or three plastic shoe box containers would fit my space better than a 10-gallon container as in the article. Thanks.

We've never had fungus gnats in our worm bins, that I can think of. We are always very careful to make sure everything added gets buried under the cardboard bedding, and I am certain that's an important step.

As for smaller: yes! You sure can. We have even had great success using 5 gallon buckets (using just the bottom 1/3 of the bucket) as bins so you can see you can use almost any size container.

Hope to get started soon. Have lots of cardboard boxes, and little shop in town sells the red wigglers as fishing bait.

I have 9 bins in plastic drawers about 1 cubic foot each and containing approx 1000 worms. I love the smaller size as it's easy to deal with quickly!

raeellis . Wow ... that's nice. I notice the label says 3-bin. I'm guessing those bins pull out with that lip made handle? And it looks like you are using shredded paper as versus cardboard?

Great idea for a bin! I love it.

I mix the cardboard and shredded newspaper together
