This will be lengthy so you might want to get comfy before you read.
We are looking to purchase our dream property that is set up exactly the way we want with 10 + acres. Problem is that it is surrounded by fields. Not just any fields but rotated fields of rice and soybeans. It is in the mississippi delta and misquetoes are seriously bad there. To the point that we were told that we would not be able to go out after dark because we'd be carried off. We raise dairy goats and garden as well therefor being out of the evening is important to us.
Here is where the questions and theories begin. I (with my pea-brain) would figure that with all the 'skeeters' in the delta bats would thrive quite well and now wonder why they have not implicated a 'natural' means of ridding ppl of intrusive/ unwanted insects using bats? Would we have a problem with our livestock if we started some bat houses in the corrals (there are large lite poles for riding at night)? I want to make sure that we are not cutting off our nose to spite our face so to speak. Are there any health concerns that we have to worry with? The research I have found for Arkansas says that all of the Ar. bats are the ones that only eat insects so I'm hoping that there would not be a problem with the animals being bit/nipped as with the vampire bats.
I also am looking at using the guano on our gardens (still reading up on best ways of when and how to use) I am very open to ideas and any knowlege from this group of bat'aholics lol ......
Personally I like bats, I just dont know much about them.
I would rather use god given natural instruments to work our farm than, rely on any man made chemical which bleeds us out from pocket book to throat...
