We have a fly problem

We have some of the plug in ones. We are killing then constantly. There has to be a “nest” or a source for how they are getting in the house. 90% have been killed in the kitchen.

We checked pantry but no food gone bad.

Walmart bag traps. Over by the bbq stuff. Home Depot has em right up front. All the same and work good.
We put out two last week. Each have almost an inch of dead fly inside and our patio flies are down maybe 80-90%. Still been cooking out too.

This will wipe their azz out. Just make sure to bait out of reach of pets/kids.

Numerous flies often mean that you have something rotting in or near your house that is infested with maggots. Kitchen waste may be the problem, or a dead animal or pet droppings. Different species of fly go after different things to lay eggs in.

If the source is inside the house, you might smell it but not always. I once had a dead rat under a sideboard and never smelled anything but did notice the flies for a while.

If the body of the fly is metallic blue or green, it's a carrion fly. Even small dead mice or small bird below a window can crank out lots of their maggots.

Good news is that once the source is consumed or dries out the maggots and the flies go away.

I think it’s pet feces close to the back patio door. We scrubbed through every possible source inside the house and not finding anything. Trash in the garage doesn’t have any flies in or around it. I bought the bag that will hang from a tree…expecting this thing creates a storm of flies
