Maybe I'm just a little strange, but I'm wanting to build a couple of bat houses to put in the trees here. I have seen a couple of bats at night, flying around the yard light hunting for bugs. Bats eat a lot of bugs at night and since we do have mosquitoes in abundance in this part of the country, it seems like a good idea to encourage more bats to live close by. These night flyers whisk through the air silently as they seek their prey. They are swift and accurate hunters.
I like to encourage all kinds of beneficial animals and insects. I make sure there are small pans of water around for frogs and lizards, so they can consume insects within their reach. I also like to make sure I have certain flowers blooming that will attract a small variety of wasp whose primary function is to lay eggs on tomato worms so their offspring kills the worms.
I figure, if I encourage beneficial insects and animals they will help me keep the population of harmful insects down without having to use possibly harmful chemicals.
