O/T Outside House Fly Control

We live 1/3 mile from a large chicken/egg operation. 500,000 chickens I think. We have no livestock. Only two dogs.

I am looking for something that I can use to knock down the fly population outside when there is a bloom. We just had a bad period last week. I went out and bought one of these Fimco sprayers from TSC and sprayed the entire yard with Tempo 20 WP. We did not see great results.

We have used the trap-n-toss pots and the quick strike mats in the past and seem to have good results, but these things don’t even put a dent in the population when we have a problem. When we have a bloom, I can fill up fly strips in an hour. I have also used a fogger, but am not sure if I am really getting any results from that either.

I am looking for a safe insecticide that I can use to knock down the population. My wife is pregnant and we have two dogs so I am hesitant to use anything too nasty.

Also wondering if anyone has had any experience with Fly Predators. I believe flies may be breeding in our dog's fenced in area and was wondering if these little buggers would help.

Sorry for the O/T, but you guys give good advice

Then we got guinea fowl. For the first time ever, we aren't covered in flies. They spend all day, every day, running around snapping up flies. They may be ugly and noisy, but they are a fly eating machine!

We had a plastic minnow bucket that walmart sold. Put a little water in it, couple inches, and a couple dead minnows. Cut them open a little and hang the bucket up. The flies enter the little holes and can't get out. Nasty but works.

Who do you think gave me the Tempo?

So in total I put 15 gallons on maybe 2.5 acres.

Maybe not enough? Also, I wonder if it has an expiration date. Stuff must be 2 years old.

We had 4 solid days of no rain afterwards and didn't see any great results.

Get a load of manure and put the fly predators in that as a giant fly trap :)

Can't offer much advice but commisserate a bit. Our area used to be a big poultry area, and you'd see the fly blooms every so often. Can remember on house a good mile from the nearest manure pit and they did get thick sometimes!

Maybe I should sneak over to the coop and dump some on their pile . . . although I doubt they have one right now since they are generally very good about getting it the heck out of the area.
