Really does help keep mosquitoes and biting flies/gnats off them. Our vet advised against fresh garlic (I knew that anyway), but they seem to enjoy the taste on kibbles. I have tried garlic drops designed for the water bowl. They were horrified I'd do such a thing and refused to touch it. I repented of that quickly.
That said, dragging 200' of hose to attempt to cover an entire 2-1/2 acres just isn't practical. For me, it's barely physically possible. I'll admit the $84/five acres/one whole season price tag is appealing. That's about the least expensive option of any of them. It'd be worth it to hire a kid to come help me drag hoses around for a day. I guess the real question is finding a truly effective spraying mechanism that gets "enough" down, and enough to persist as advertised. This is definitely in the hopper to investigate further.
I really wanted guinesfowl to work. I think they're just so cool. The noise doesn't bother me and they're the best flea and tick getters ever. Between my hyper kids wanting to herd something and the number of predators we've got around here, from what I'm turning up in research it's just not worth it after all.
