I use these to keep coyotes away from the ferral cats that I feed & shelter.

No nos sirvió poner este producto porque los mapaches siguieron viniendo a hacer destrozos en el jardín a pesar de estar en funcionamiento las luces intermitentes.

Had these for a few years after a Fox attack on our chooks and no problems since - either they work pretty well or we have been exceptionally lucky.

Simply effective... We purchased these for both ourselves and a friend of ours, we both own chickens and at the time were having issues with foxes. If you didn't know this, a fox will kill everything, they don't just kill or take one, they kill them all and take one. Not a nice site I can promise you.This device is simple, easy to fit, doesn't require batteries as it is solar powered. It comes on whenever it gets darker (mostly duck till dawn but a dark storm will activate it too). Basically is projects a strong red LED that flashes on a regular basis, the idea is that this flashing LED misleads predators in to thinking that they are being watched and so will go elsewhere, mainly due to the fear of discovery. It is weatherproof and apparently will last approx 3-4 years. Ours is nearly two years old, battered and weathered but still going strong as advertised.From our viewpoint this has proven to be a great buy, (not wanting to jinx ourselves) as we haven't had any for or other predator issues since first setting it up, so five stars a for a truly excellent bit of kit.ProsEasy to fit - one screw will do itNo batteries or mains supply neededWorks all year roundKeeps the predators away (foxes in our case)Charges via solar powerBright red flashing LEDConsnone so farAlmost two years and no a single issue yet. Highly recommend one if you have predator issues.

Its easy to put up leave out in sun when you get it works ok after that easy to move around

We live in a small private community in North Georgia where the deer are plentiful and very tame. Many in the community feed the deer, which only adds to their pacificity. Over the past two years+ I have tried a number of deterrent options: scarecrow sprinkler, Liquid Fence, wireless deer fence, as well as several 'home remedies'. I work from home, with a window in my office where I can watch a good portion of the area that gets the most 'visits' and security cameras that cover the entire exterior perimeter, so I have the benefit of knowing the paths most commonly used by my 'visitors'.Like humans, all deer are different. Some are deterred by some things, not so much by others. For example, Liquid Fence has worked well with most, but there have been a few bucks that almost seem to like it's smell - munching down some hostas within a few hours of them being saturated - and in full daylight. (Yes, I know hostas are like 'deer candy', but I try to grow a few near my home).Each summer, when fawns are growing, the population increases and natural growth is getting less plentiful, the damage understandably increases. This summer was the worst I've experienced with deer coming to my yard morning, noon and night. While none of these deterrents are likely to stop a starving animal, even using all of my previously mentioned deterrents, the number of deer incursions was increasing. That is when I decided to try this device. I must admit that at first, I was skeptical - but considering the cost, I thought it was worth a shot.How I evaluated this product:First, I installed 4 of the devices, following the guidelines of the manufacturer, which is basically positioning them at eye level and forming a perimeter around the area you want to protect. I then positioned my security cameras to monitor that section of our property and smoothed the ground so that deer tracks would be easily visible.Over the following days/weeks, I would check the ground for tracks as well as damage and adjust these devices along with my other deterrents, using them as my outer perimeter, thinking the others might 'pick up the slack' for any that are not amused by the red light and of course for the day time foragers. Much to my amazement, once I positioned the nite-guards, directly in line of their common paths, then purchased two more to create a cross-hatch pattern, my incidents went from almost nightly visits to NONE. Over the past four weeks now, I have had ZERO incidents. Not only have no deer come into my yard, but they now give it a wide berth, even in the daylight.My recommendation to any using this without success is to re-evaluate where you are positioning them and make sure you are covering the area from the direction the deer actually come. While nothing is going to work all the time for everyone, I have found this device to be a welcome addition to my deer deterrent arsenal.

I bought a set of four to deter coyotes that are prevalent in my area. I keep sheep, chickens and a horse on my property.My property is in an area probably best described as suburban. Though my home is surrounded by farmland, a half mile away in each direction are subdivisions with newer houses. My house is on a fairly busy road, halfway between a small town and a small city. I bring it up because other reviews have speculated that Nite Guard may work better in rural areas than suburban.I have had the four Nite Guards in place for 69 days, placed at the correct height for coyotes, and rotated their position every 5 days or so. About one month ago I found fresh coyote scat in my field, less than 5 feet from one of the Nite Guard lights. I should have returned them then, but I didn't because I hadn't actually suffered any losses and thought maybe it was working, despite the scat.Last night I lost eight chickens to a coyote. I heard the commotion start at 4:30 in the morning - middle of the night, with the four Nite Guard lights functioning in the field - and my neighbor saw a large male coyote make off with the last chicken at 7:30 this morning. The lights didn't deter the coyote(s) during the night while the lights were flashing, and the male coyote my neighbor saw was so bold as to take the last chicken within 5 feet of my house in broad daylight (so no residual, lasting deterrent effect, either).The company offers a 60 day money-back guarantee. I'm going to ask them to honor the return even though I'm 9 days past the limit. I can't recommend this product and suggest you save your money.

We actually think of our chickens as pets...they come to me when called, they eat out of my hand, they listen attentively, do tricks for cottage cheese, and crack me up. Yet, unlike our other pets, they make me eggs for breakfast and fertilize the yard at no additional charge.So I want to keep em around.Unfortunately, our house backs up to a prarie and deep woods so everything from coyotes to deer to raccoons etc are visitors...Although our coop is very secure, raccoons can get into most locks you wouldn't think possible, dig under the coop, and so can coyotes. And if a coyote finds your coop, you will rarely be able to EVER keep him out again. Possums can also get in very tricky ways.So we had concerns. I just read about this in a magazine I shutter to admit I read called something like Backyard chickens. Although there is an ad for it in the mag as well, it was cheaper here. Then a worker at the feed store mentioned it. So I got it on Amazon.So here's the test. We keep the coop purposefully by our house so the chickens are less seen, heard and smelled to the wrong predators as they would be in the very back of our yard. But one attack would be too much.To test it? I knew raccoons had found our compost bin at the very back of our yard after I had left it open and were coming back to visit every night, with pawprints even on our deck after we grilled. So I first put this on the compost bin, knowing they'd return. They haven't touched it since and it was OPEN for the taking. Good news.That said, in order to be most effective read the directions about placement height and everything I read says to periodically move it around a bit on the coop so no animal gets used to seeing it, consequently, making it seem less risky to them to explore.If there are a few ways a predator might get to your pen, you may need more than one.Works via a red blinking laser light...I have no idea why unless word is out in the animal world that that is what a hunter's laser looks like... :-)Runs on solar power and turns itself on and off. It is NOT activated by motion...but, though I thought this was the case, I guess it's better that it's not because by the time they are THAT close, chicken meat may smell too good to resist and this way they don't have to pass in front of it to be thwarted by it. Just seeing it keeps them at bay.P.S. Have a free range area with an open top? I continue to read that crossing fishing line across the top then putting streamers of bright orange tape hanging down to flap will keep hawks from carrying away your hens, as well as climbers.Negatives: Best to have several yet it's just too pricey to stock up as I wish I could for all sides of my coop. However, this appears to be the only manufacturer.Positives: That's obvious.
