Randy, be careful how much fish you add to your BioPod before the colony get's completely established. If a few houseflies get inside of a fully functional BSF unit they probably won't lay eggs and if they do then the eggs probably won't develop into adult flies. But, since your colony is still small you'll probably see some housefly larvae surviving and passing through into the collection bucket. It's not a big deal, just be extra careful with sanitation while the houseflies are present.
I'm starting to think it's not wise to add fish, or maybe any animal product, to a BSF colony if there is a significant amount of vegetable matter being processed.
BSF seem to prefer fruit, vegetables and grains over animal products. If there is a large amount of vegetable matter available I've seen the fish/meat sit uneaten until the more preferred scraps are eaten. If the BSF don't begin eating the animal products immediately this can lead to attracting undesirable fly species into the colony. As I said earlier, a few pest flies won't crash the colony, but I recommend refrigerating the fish/meat and saving it until the colony has limited amounts of other items to eat.
I'm glad the eggs developed Randy, I'm sure you'll see some adult BSF from the wild population visiting your unit soon. They love this hot weather.
