Stram QuikStrike Fly Bait Spray - 1lb Fast-Acting Fly Killer | Outdoor & Indoor Pest Control for Home, Farm, and Stable Use

So we foster dogs. We have a large dog run and as you can imagine, there's poo. Despite mucking poo and pressure washing twice a day, the flies are unreasonable.I originally got the granules and they work great, but this stuff works better. I didn't really want to use this powder as spray ..at least not in the dog run. Dogs do dumb stuff like lick walls, lol. So I very very lightly sprinkled it evenly over my soiled poop scoop after a muck out and washing away any remains. The only poo the flies have access to is on the scooper. They land. They die. By the hundreds. It's lovely.
