X2. The fly traps do work really well and your placement advice is spot on. I tried not using them this year because I swore I was attracting by neighbors flies. Good to know about the predators. I won't bother.Amazingly, I've had few flies this summer, despite rain the entire month of May. We are hot and dry for the moment. Go figure.
I stopped buying fly predators because, like other folks, I couldn't justify spending $18+/month on them when all the properties surrounding ours are overstocked with cattle, sheep, goats, mini donks. Not to mention the native and exotic wildlife populations. A losing battle with the predators, in my situation.
What has helped so far are the disposable hanging fly traps that come with attractant. You add water and hang them in specific locations. The location is important since you do NOT want to hang them in or near your barn, chicken coop, etc. Wind direction, location, height for hanging the fly traps are all important, lest you end up attracting flies from elsewhere. Might not work in small, backyard situations, but I put them in strategic locations in the spring at the first sign of flies and they tend to knock out a large portion of the adult flies. They do smell horribly when filling with flies.
I've found the disposable traps at "Wally World" (garden dept) for way less expensive than at feed stores or TSC. Again, your mileage may vary...
