We have the House Geckos helping take care of the wild bug problems, though the geckos have gone into hibernation now. One summer evening, we pulled into the driveway, and before getting out of the truck, my wife and I counted 22 geckos hanging around the front porch light. That was just the ones we could see, and 22 was where we stopped counting.
Cool little lizards, and man are they voracious at packing away the bugs.
