Homemade Fruit Fly Food


Anthony Hundt

8 bananas
1/4 cup sugar
rolled oats (oatmeal)
1 packet bakers yeast

Put banana and sugar in blender and mix until the banana is liquefied. Mix in oatmeal until it becomes firm, but still moist. Put mixture in wide mouth quart canning jars. Add a few granules of bakers yeast to the surface and add about 30 fruit flies. Cap the jars with a paper towel folded in fourths held on with a rubber band. Substitution with other types of fruit also works.

Variation, use the following ingredients:

1 cup banana (about 2 bananas)
1 cup apple sauce
1 Tablespoon vinegar
2 cups oat meal

"Raising Fruit Flies", Nancy Nehring
Reptiles Magazine, October 1995, pp. 26-28, 30
1 cup water
1 tablespoon cornmeal
1 teaspoon powdered agar
1 tablespoon molasses
1/8 teaspoon calcium proprionate (optional)
1 package bakers yeast

Mix all ingredients except yeast, then heat until boiling. Quickly pour mixture into clean culture jars. Cap and let cool to room temperature. This mixture can be stored in the refrigerator with a tightly capped lid until ready for use. When ready to use, sprinkle a couple granules of baker's yeast on the surface and add fruit flies. Calcium proprionate is a mold inhibitor used in bread.

baker's yeast
brewer's yeast
instant potato flakes
tegosept (methylparaben)

To prepare dry culture media, mix 1 part brewer's to 10 parts instant potato flakes by weight. When ready for use, mix 4 grams of the mold inhibitor, tegosept (methylparaben), to 1 gallon of hot water. Let cool and add an equal amount of water to the dry culture media (by volume). When the mixture solidifies, add a couple of granules of baker's yeast to the surface and add fruit flies. Calcium proprionate may be used as a substitute for tegosept.

From the Bugman: The tegosept is a dry powder. We use the tegosept dry in the mix and store it in zip lock bags.When we mix it with water 1 part of the mix to one part water and sprinkle a few granuals of baker's yeast on the surface. No waiting for the mix to cool as we start with cool water in the first place.

By far our favorite mix AND the easiest to work with.
