This time of year brings reindeer to mind. Unfortunately, some of our yards are at risk to other deer that eat favorite plants and destroy gardens. Nationwide, the deer population is at an all-time high, and these beautiful woodland creatures are invading suburban homes as never before. Their search for food is not only destructive, but is a health hazard as well. Because deer ticks carry Lyme disease, we suggest a repellant. In a recent test of deer-repellent technology, apples were used as bait to entice deer accompanied first by several types of commercial deer repellents and then by many time-honored household remedies, such as hot sauce, perfume and baby powder. None worked very well or for very long. So, what successfully kept deer away for up to a full week? Believe it or not, chunks of deodorant bar soap hung in a tree. And that's the On The House Tip for today.
