This is my experience too. Fortunately our 27 acres has about 10 acres of grass fields in 5 separate areas, one field 1000’ long, and some neighboring pastures adjacent to some of our wooded areas. I’ve got a few boxes up now but this is inspires me to make some more for next year. We could probably support a couple dozen!
Another thing on my “list” is to build a couple of good bat houses. After several years lull I’m finally seeing a resurgence of bats in last two years. I love watching them cavort over the fields in the evenings. I suspect the mosquitoes don’t like them as much.
