I'm looking at at 25°f on my dash guage so a few days of cold w/snow they say then a few days of 50's then a couple more cold days then close to 60. Hope this kill all mosquito eggs/larva however they winter. Maybe the ridge the other side of the creek should be bought so as to dig a bat cave. A HOA told home owner No birdhouse allowed. Built a big box with the right openings for bats. Endangered species so HOA's orders could not be enforced ,and had to pay homeowners defence costs when they lost in court. Gotta do some research, me want squito eaters nearby.
