Excelsior (makes 25 fruit fly cultures)

Our Excelsior is a premier source of high-quality aspen excelsior, commonly referred to as wood wool. Excelsior serves as an excellent medium for fruit fly cultures by increasing surface area for fruit flies, providing them with more opportunities to climb, mate, and lay eggs.

Using Excelsior instead of coffee filters offers several advantages, including higher fruit fly yields and a more stable culture. Additionally, Excelsior is produced from renewable resources and is compostable, making it an eco-friendly, sustainable product.

This bag of Excelsior can create 25 or more fruit fly cultures.
