The other flies will show up initially, but the BSFL are voracious and will eat any other maggots that get in their way. They eventually overpower anything else. Once they've become established, the smell changes and doesn't attract the other flies.

That's my understanding from what I've researched thru reading and videos.

I checked the box this morning but so far nothing appears to have found the food. Cooler temps I imagine, but I've got 10,000 larva (maggots) coming. Should be here around Wednesday or so.
