Fly Exterminator 1,000 Size Natures Good Guys

The key to using this is before you have a fly problem! They work great but you may not see a huge difference in the amount of flys if you already have a huge problem. These take time to work they attack the fly larvae before they turn into flies. So use as a preventative before your problem starts.

I bought it twice but Flys were still bad..finally got solar fly trap..problem solved

Got to put out near chicken pen.. lots of flies this year. Too soon to see if works well

I set up auto delivery as suggested. A couple of weeks after the second delivery my chicken coop is covered in flies and it wasn't before; I was hoping to prevent the flies! I emailed the company and got some sort of chatbot response. Also note: I only have 4 chickens. Disappointing.

They are working so I’m happy!

I think it's working. We had a lot of flies at the chicken coop and now there's not a fly on 1 single poop. I have 8 chickens and I bought the 1,000 count. Towards the end of the month, I'll see if the flies come back and then I'll know. But I'm pretty sure this works!Update: 5 days after this review, we have flies in the chicken run again. I have 8 chickens, 4 are young with small poop and they free range often. So maybe it worked for 2 weeks, I'm not sure.

Bought 1000 of these for a 12 x 14 chicken run. Placed it underneath a tree right next to the run. Over a month later I still have a bunch of flies.

I only use this company now as they always send exceptional quality & have a great selection. I've hatched praying mantis & lacewigs so far. Hoping the fly exterminator helps our fly problem.
