Doesn't surprise me. I live in a downtown and all the numb-brained residents think its just dandy to chemlawn their 10x10 lots. My residence is in a bit of a valley and sometimes collects moisture in the back. Needless to say we get mosquito problems at times, and I just realized the other day there are no fricken bats at night! Used to seem them all the time. Probably dead from all the chemlawn treatments.
