One of the big reasons that is entirely stupid and preventable is that there used to be a regulation that all trash had to be in metal cans with tight lids. It helped a lot. Then the usual suspects (capitalism) got rid of it and now the trash is just in piles and piles. It’s awful. It also doesn’t help that now places aren’t letting staff take food home and refuse to give it away and are even locking dumpsters to prevent hungry people scavenging. Just means there’s more food waste for the rats to feed on.
