Update: I put half of a Mosquito Dunk in a 1.5 gallon sprayer full of water and let it sit for 2-3 hours Thursday midday. I sprayed Thursday afternoon, Thursday evening, Friday morning and evening, Saturday morning, and Sunday morning. I am spraying the floors of my three stalls, the feed room, and aisleway, and I’m spraying the doorway area at each end of the barn. I’m also spraying the manure cart, which is about 70’ from the barn. I skipped spraying the manure cart on Saturday. On Friday, I also brought the sprayer back to my house and sprayed around my back deck. The flies have been so annoying out there that you can’t even sit out there peacefully. I sprayed the barn area again this morning, Monday, and I’ll need to refill the sprayer tomorrow morning, so it looks like I’ll get about a week out of the mix if I’m spraying once a day.
Friday morning, I was surprised to find the fly population noticeably reduced when I went into the barn for morning chores. I thought it had to be a coincidence, a fluke. By Friday afternoon, after it had really warmed up and the sun was shining brightly and there were still no real flies to speak of, I became convinced it wasn’t a fluke after all.
When I did chores Saturday morning, I decided I’d try to count the flies. Yes, count them…as in there were so few I could count them. I counted five. This morning I counted four while doing chores. My barn is virtually fly free. It is amazing.
I didn’t tell my mom (who lives with me) that I had sprayed around the deck and around the house. I sat out there for about ten minutes Saturday evening and saw exactly one fly. I asked Mom how the flies were when she was out there. She thought a minute and replied that, come to think of it, she didn’t see any.
@Simkie Thanks for the info. I declare the Mosquito Dunk tea a great success!
