Josh's Frogs Melanogaster Fruit Fly Media is highly regarded in the industry! Each bag of Josh's Frogs Melanogaster Fruit Fly Media contains 5+ cups of fruit fly media. A bag of Josh's Frogs Melanogaster Fruit Fly Media makes 15 - 1/3 cup cultures or 10 - 1/2 cup cultures.

Moisture Retention

The biggest issue with fruit fly cultures is low humidity. That's why Josh's Frogs Fruit Fly Media uses powdered potatoes instead of potato flakes. This allows for a more thorough mix of the ingredients, but also allows the media to hold more water. This keeps the media from drying out and prematurely killing the culture.

No Nasty Odor

Josh's Frogs Fruit Fly Media contains two natural anti-bacterial/anti-fungal ingredients. This eliminates the nasty smell of a bacteria/fungi infected culture. Many customers compare the smell of our cultures to freshly baked bread.

High Yields

Bacteria, fungus, and molds compete for nutrients with the fruit flies. This fruit fly media fends off these invaders so your fruit fly cultures produce greater and healthier fruit flies. 

Directions:

  1. Mix contents of bag thoroughly
  2. Pour ¾ cup of boiling RO water/bottled water over ½ cup of media (don't stir, just let it soak in! It may take a couple of days to absorb fully)
  3. Add a handful of excelsior to the cup
  4. Cover the cup and wait for it to cool
  5. Add 25-50 flies

Cultures should be kept below 85°F and will start producing flies in 12-14 days. If the cultures seem to be drying out (or molding), spray with RO water and use more water when making cultures. Josh’s Frogs recommends keeping the cultures in a plastic drawer system to prevent them from drying out.

This media contains a mold inhibitor.

Pro Tip from the Manufacturer: It's best to store media in the freezer so it stays as dry as possible. If the mold inhibitor within our recipe is exposed to moisture before a culture is made, it can deactivate the ingredient.

Go-To for Reef-Safe & Light-Weight Sunscreen
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
Favorite sunblock to travel with. Appreciate the simplicity of it, and the fact that it rolls on and rubs in smooth. Of course the iconic scent is also a plus.

Great choice
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
After I suffered a second-degree burn from steam, I was told by my doctor that I would have to keep my new fresh skin sun-blocked for up to a year to avoid any scarring or hyper pigmentation. This has been a great selection as it is a roll-on, Which helps a lot with preventing messes that can happen with traditional sunblock bottles. I also like that it is easy to travel with, and the fact that it is zinc based.

My favorite new mineral sunscreen!
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
This is my favorite new mineral sunscreen! I've been searching for years for a product that is easy to apply, not messy, and doesn't show up too white. This roll-on is the perfect solution. I keep it near the front door and quickly roll the sunscreen on my hands, arms, and chest before leaving the house. The sunscreen applies so quickly and uniformly-- there are no bare spots or messy globs to rub in. Also, the roll-on keeps the sunscreen from oozing out of the tube and getting all over everything. Finally, the roll-on method also eliminates the frustration of having half-filled tubes and pumps where you can't even access the sunscreen when the tube gets low. Here's hoping this doesn't happen with the roll-on. Thank you Sun Bum for creating this wonderful product. I also love the reasonable price.

great product - it must be blended in well
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
Love this stuff. The roll-on makes it easy to apply on the go. It leaves a white streak unless you blend it in. I don't mind the white streak - at least I know I applied the product.
