Oh, yeah - I forgot about bats! We always had bats in the neighbor's barn growing up, just a few. Imagine my surprise when visiting a friend in Cambridge, Massachuasetts, which is a city, and at night they'd sit and watch their neighborhood bat dine on the bugs that were attracted to the streetlight! They really are nothing to be afraid of, and are helpful pest control. Another way to reduce the mosquito population is to make sure there are no extra spots of stangnant water aroung - no old tires or buckets out that have collected rainwater - these are perfect mosquito breeding grounds, so just dump 'em out!
