Fruit Flies - What do you use

[Tzunu un]

It's important for me to have something that I can throw into the compost bin.

After trying a few things, I use both coffee filters and excelsior in a modified manner.
(Maybe someone else has posted this before but I'm not sure.)




I tried excelsior alone and it worked but was tired of the bits falling out into the flies when feeding and also having liquid in older cultures coming out.

I tried coffee filters alone and the yield was lower and also they cultures would eat them....especially the hydei cultures where the filters would turn to mush.

I tried combining them with the filter in the bottom and the the excelsior, but this still led to problems with bits of excelsior falling out.


The solution I found that works best for me was to use both, but to invert the set up and also cut a hole in the center of the coffee filters as well:

- Take 3 coffee filters, stack and fold in quarters and snip off the point by 1/2 inch to 1 inch.
- Unfold the filter stack and put a baseball sized ball of excelsior in the center. The filter paper stack is like a cup (looks like cupcake liner) around the excelsior.
- Invert this and put in container with media, pressing until it touches the media.


The flies emerge from the hole in the center of the filter. The filter acts as a cap to keep the excelsior in, while the folds of the filter along the sides of the container absorb any excess liquid.

This solves the excelsior problem, the liquid problem, and the coffee filter disintegration problem while keeping production high.


I tried adding pics from my computer to show what it looks like, but for some reason the forum site won't let me do this today.
I get an "This is not a valid image file" message even though it's the same format I've used before (also changing the format / size doesn't work today).
Any one else have have this problem recently?

Excellent idea!

Some great suggestions here and great future topics of interest.

I can't believe that the direct photo uploading option on the forum has not been fixed in 4 weeks!

Ok, I broke down and signed up for Photobucket (slow and ads for the free version)

Here are some pics of the post from above.

Any updates from anyone on this? I've been using mesh for about 6 weeks (so not long), but so far I am happy with the results!
