Josh's Frogs is a leading source of quality excelsior, also known as wood wool. Excelsior is ideal for use in fruit fly cultures as additional surface area for fruit flies, allowing them additional places to climb, mate, and lay eggs. Using Excelsior in place of coffee filters provides several benefits, including higher fruit fly yields and a more stable culture. Excelsior is also made from renewable resources and is compostable, making Josh's Frogs Excelsior an environmentally friendly, green product. 

 

This bag of Excelsior makes 20 or more fruit fly cultures.

Works great! Review by Michael

Works very well for keeping the fruit flies out of the media. (Posted on 1/2/2018)
Great product Review by Grum

Previously I had used paper towels for my cultures, but this is far easier to use and so far it seems to work better. The paper towels would get damp and limp from the humidity but this has no such issue. (Posted on 8/11/2016)

This is a must have for culturing ff's! The last bag I bought lasted two cultures per week for 4 months, a great bargain! (Posted on 4/13/2011)

I find this stuff to regulate humidity in the culture far better than most other methods. My only complaint is it is a bit messy at times and I usually have to shake the loose stuff from the clump before it goes into the culture. But its cheap and it works! (Posted on 3/17/2011)

I've tried all kinds of different media for pupation and the fine excelsior outperforms them all far an daway! I recommend it for anyone trying to culture flies. (Posted on 3/17/2011)

Wow this stuff is great. I couldn't find excelsior anywhere where I live (Norway), but I finally have it now. No more nasty looking cultures for me, with soggy filters and dead flies stuck all over the sides. I also want to note that I had some problems with my address because I live in Norway, and customer support was spectacular in helping me get that problem worked out. (Posted on 3/17/2011)

This really is excellent----ever since I switched from the regular excelsior to the fine-grade, I have seen a dramatic increase in FF productivity. Both are great mediums for culture enhancement, but I think the finer grade produces more flies. (Posted on 3/17/2011)
