I have attached some items that may interest some of you who are close to the neighboring community at the rear of home. I have placed the cheapest motion sensor light, motion alert, and snake a way for you all to consider from Home Depot.
I have used the motion sensor alerts before. They do sound an alarm during the day or night as well as turn on a lamp or radio to alert you of motion outside. I suggest you use this item if you don't have children who will be playing in the area you intent to place it in. You may cut it off to keep from being annoyed and defeat the purpose by not turning it back on at night.
I use the snake away because I have railroad ties at my lawn border and snakes tend to take up residence provide by ths skin they shed on it. I also have the large feild/vacanies next to my opposite side. I create a border against snakes for the sake of my dog and household. You may not need all of these things but, I like to prevent the need. Henry
