Why do restaurant fly lights and cleaning fail to stop flies?

Fly lights and standard cleaning routines like mopping floors and wiping tables miss the hidden breeding sources where flies reproduce, such as drains or incoming food deliveries. This ongoing infestation persists in kitchens and dining spaces despite daily maintenance, driving owners to constantly search for root causes.

i tried the soap + white vinegar "hack" didnt work, i tried it in various different formulas/ratios and they just kept landing on the rim of the cup/bowl so it didnt not work at all.source ↗

the most annoying thing is that they are in my bedroom, amd i have hoovered, cleaned surfaces with bleach, cleaned / shampoo'ed the carpet, empited out all drawers and cupboards but there is nothingsource ↗

I’ve been struggling with a resurgence of flies after almost completely getting rid of them- then this happened- just now I was washing the dishes, and I had a scrub daddy sponge in the sink besides the one I was using. I went to move it and SO MANY flies came crawling out of it!!!source ↗

These have been hanging around in my bathroom, saw some in the kitchen too. What’s causing them?source ↗

Running a back-of-house space (or managing one) and flies are a constant fight, sprays aren't great around food prep, and swatting one-by-one obviously doesn't scale.source ↗
