Safe, Humane Deterrent Helps Protect Your Garden
A huge amount of time and energy goes into keeping your yard and garden looking great, so it's only natural that you want to protect them from damage caused by hungry wildlife or local dogs and cats. But there are lots of reasons to avoid chemical deterrents, traps, and hazardous electric fences.

Whether you're a dedicated organic vegetable gardener or a parent looking out for the health of children and pets that play in your yard, you'll appreciate the simple, innovative, and effective water-based concept behind the Scarecrow Motion-Activated Sprinkler. It's also a great choice for neighborhoods where fences are prohibited and for people who consider wire fences and other visual barriers unappealing.

When the ScareCrow detects an animal it instantly releases a short but startling burst of water. The sudden spray of water and the movement and noise of the sprinkler scares animals away. Animals associate this negative experience with the area and avoid your yard in the future.

Versatile and Broad-Reaching for Maximum Effectiveness
The Scarecrow is versatile enough to keep deer, rabbits, and other foragers from snacking on plants and bulbs, to prevent dogs from digging up newly seeded lawns, to keep the cat from using your garden as a litter box, and to scare predators like herons and raccoons away from your fish pond.

The ScareCrow's motion detector is powerful enough to guard an area up to 1000 square feet of coverage with a single sprinkler. For added coverage, Scarecrow sprinklers can be linked in series to guard larger spaces.

Efficient Design and Easy to Set Up
Setting the Scarecrow up is fast and easy, and doesn't require any special tools. Simply install a standard 9-volt battery, connect the sprinkler to your hose, push the 17-inch stake into ground to secure the unit, and set the adjustable sprinkler arc to cover the area you want protected.

Customer Reviews:

  • Motion activated relief
    I bought one after using sprays like "Liquid Fence" and "I Must Garden" for years. The Liquid Fence was 100% effective for a few years, but then the deer decimated my garden overnight.

    I heard about this product and bought one (Liquid Fence in concentrate costs $39.99). I was so pleased with it, I bought another, and set it up at the other end of the garden. Although my garden is not huge by any means, there are shrubs and other plants that 'block' an unobstructed view of the entire garden for one unit to protect it all.

    So far, so good, knock wood. My only complaint is that even with plumbers teflon tape, it is impossible to stop the leaking entirely. Also, one of the units seems overly sensitive - 'recognizing' my wife every time she steps out on the patio, and going off. (The patio is almost 90 degrees to the right of the unit). But it makes me feel good to see that, so who cares.

    For the money, it is any excellent buy. Like some other reviewers, I, too, would like it better if the construction was more heavy duty and had more metal in it. But, it works, and works well....more info
  • Only thing that worked and Contech has a great warranty
    After battling with the neighbor's cats for a couple of years over my flower bed/cat toilet and losing every time, I plunked down the $$ for this pricey deterrent and I FINALLY beat those damn cats! No more toilet. Unfortunately after about 8 months my scarecrow stopped working and I thought I was going to have to double-down my investment. Not so! Contech guarantees their product for 2 years. I contacted their tech support and when they determined that it could not be fixed with a part, they shipped me a brand new scarecrow. If you aren't sure because it seems expensive, BUY IT. It will solve your problems AND the company that makes it stands behind it 100%. No excuses, attempts to dodge their warranty, they simply fulfilled their promise. ...more info
  • Rabbit Defense
    The motion-activated sprinkler is great. However, it would be nice if the support stem was shorter and with a 90o hose adapter. This will allow the unit to be installed closer to the ground. Rating would have been higher if the sprinkler head had the capability of being adjustable up or down and not just left or right.

  • Scarecriw works
    I bought the scarecrow about 6 months ago. The product really does work. Deer were eating tomatoe plants but after installing the scarecrow the tomatoe plants grew untouched without the protection of a fence. The only downside is that I need to shut it off when it gets windy becasue it senses leaf movement which triggers the spraying....more info
  • scarecrow motion sprinkler
    I've only had this product for a month or so but it is WONDERFUL. We have spent hundreds of dollars on fences, sprays, motion detectors, and dozens of other worthless items to keep the CATS out of our yard that did not work. I will admit it may get a neighbor once in a while. But even the sound of it going on chases the cats! I am looking to purchase another one for another section of the yard! Our back yard is useable again and I am much healther! Thanks Contech for a great product! ...more info
  • May not work with cats.
    This has been set up for a week now. The manual does state that it may not work with cats. The cat tearing up my yard has so far not set this off. In fact the cat does turn on my porch lights since I have a motion sensor for them, then she sits down next to the Contech and stares at the house.

    I on the other hand set the damn thing off all the time. Soon we will have water rationing due to drought. Then I will take to chasing the cat down and beating it over the head with the thing. (Just kidding... sort of...)

    I can't wait to find out what the local skunks think about it...

    -After more than a month, it would appear the look of the thing inhibits the cats more than the water. I am still not sure they even set it off...-...more info
  • Fantastic pet deterrent!
    This thing really works to keep the cats out of the plants and has a nice side effect of occasional watering!...more info
  • They do the Job
    It's nice to buy something that works and works as advertised. I am very pleased....more info
  • Works great however one issue to consider:
    I first have to say I love the photos that people have posted here.

    Secondly and most importantly, this item WORKS. In essence, it is a garden sprinkler with a built-in motion detector. The detector, when activated, will engage the sprinkler to spray for a total of THREE seconds. The unit will then pause for EIGHT seconds before engaging again if there is motion (by motion I mean changes in thermal energy.. this is what the unit detects). You can also set the sensitivity level as well as adjust the depth and breadth of the water spray.

    I would have given this item five stars had it not been for one issue. The issue is my "backyard" has no grass and the only method of anchoring this unit down is with the supplied stake. I needed to place this item on my patio table's umbrella hole (secured by a two-by-four I locked it in place to) for it to be able to stand upright. This is my only gripe. However my case I am sure is not the norm. If you have a backyard with grass, then this item will work wonders for your pet deterrent needs.

  • Scares The Deer Away
    Deer were destroying our gardens and deer repellents weren't working. I purchased two Scarecrows and so far the deer have stayed awayed. The first couple of nights I could hear the Scarecrows going off but it quickly stopped after that and so far so good. If it stays this way then the Scarecrows were worth every penny....more info
  • best garden thing in the world
    I love this, it not only keeps out marauding browsers such as deer & rabbits but also neighbor dogs,children & other garden pests, the only disadvantage I have found is not being able to put it out when there is a risk of freezing (or when you forget to switch it of and get an icy blast of water when you are checking the tomatoes)...more info
  • Bought another one
    These work great ...I couldn't wait to get it set up as soon as it arrived. I used a LESS than fresh 9v battery and it worked OK. Within 2 weeks it was less than reliable, as a matter of fact it wasn't working at all, most of the time. I got out the owners manual and began to trouble shoot the symptoms. First off a new copper top battery, next a towel to dry off my face, finally I fired up the laptop and ordered another one. My problem was a dead battery, that was about a month ago. Since then I've installed a second scare crow sprinkler and they both work great.

    I would give 5 stars but they are kind of pricy, so I dinged the review a little for quality ..... its all plastic, ...more info
  • great product so far
    this seems to work at keeping animals from raiding or garden so far!! I forget about it and get sprayed all the time...more info
  • Sprinkler
    This sprinkler works well to keep our pets away from our garden area. The sensor needs to be kept clean or it won't work well....more info
  • This is a GREAT product
    I added a Nelsom hose water timer to mine so it comes on at night only, the only thing I did not like is the sprinker is on top of the sensor it is too high for what I needed. I solved this by removing the sprinkler and running a hose to the sprinkler then put the sprinker on a low stake to keep it at ground level.. problem solved . I use this for my Koi pond to keep the racoons away at night it works perfect!!...more info
  • Works great for turkeys
    Turkeys were tearing up our garden on a daily basis. After installing the crow, we have only experienced minimum damage on a sporatic basis. It really works....more info
  • Scarecrow scares raccoons some of the time
    I bought this product to scare raccoons away from newly planted ground cover, which they dug up every night in their search for grubs. Frustrating! I had tried to foil them with just about everything, including sitting up at night with a shotgun, but the devils knew when I was there and waited until I was too tired or cold to stay. Then they came out to do their dirty work.
    The Scarecrow worked well the first several times, until the masked bandits somehow figured out how get under the radar of the motion sensor. It then helped to move the device so that it targeted them from a different direction.
    This product works well--I can vouch for that since it has gotten me, my husband, and the gas meter man soaked more than once. But raccoons are wily critters. Make sure you change the Scarecrow's location every few days to make them think they're being ambushed from all sides, and it should drive them off the area you're protecting....more info
  • Seems to work
    My neighbor's dogs were making use of my lawn on a regular basis.

    Since the scarecrow I have not found any more presents in my yard....more info
  • Works as advertised
    Great product , just a little delicate on sprinkler head. Had one break off when it hit the ground accidentally. Thought it was beyond repair. Used pvc pipe cement overnight and reassembled. Works fine since crack was on low pressure side of sprinkler.Keeps cats, dogs and unwanted trespassers out of my yard....more info
  • The most fabulous deer deterrent in the world
    I love this product. I have had it for several years now and every spring when the deer come to munch on all of my flowers I put this out and have no more problems. It runs on a 9volt battery and I put the hose on a timer for the times when they come and it works great every time. Keeps cats out of the flower beds as well. Now when a cat walks down the street the go to the other side of the street and stay out of my yard so they don't get sprayed. It is also a more humane way to deter animals than using hot pepper spray....more info
  • Keeps the birds off my tomatoes - and the kids out of the strawberry patch!
    I purchased this as a last-ditch effort to keep the local blackbirds from raiding my tomatoes (I like to let them vine ripen), and found that it works well at a range of 3-5 metres. I am surprised by reviews which say this does not work for smaller animals, as I have had great success with this product - it quickly provides a strong burst of water, and most animals flee immediately.
    Has also provided many good laughs when my neighbour's kids try to help themselves to my strawberries! They have learned to ask first, so that I can switch it off for them!...more info
  • Lifesaver
    The scarecrow is a true lifesaver.... for my goldfish at least! I struggled with a cat problem for several months, losing 10, perhaps 20 goldfish that resided in my outdoor garden tubs. I've physically chased the cat away, hoping it would have some sort of lasting "scary" impression, but my goldfish population kept dwindling. I even tried using rosemary/lavender oils, scents that are supposed cat deterrents, with even less success. I almost ordered a batch of the fox urine (yuck) repellent sold online, but decided against it after reading the heaps of bad reviews it garnered. And then, 20 unfortunate goldfishies too late, I stumbled upon the water scarecrow. At first I wasn't too thrilled at having to spend over 50 bucks on a cat deterrent, but I had already spent more than twice that on the cost of goldfish (yes yes, I know there is no cost to be placed on innocent lives) so I did the math and knew it would have paid for itself, if it did infact do what it had claimed. What actually sealed the deal for me was reading all the reviews on here. SOOO many people raving over this little gadget, loads of stories that started out so similar to my own, but instead ended happily ever after.... with the help of the scarecrow of course! So I bought it, and have NEVER LOST A GOLDFISH SINCE. I've even absentmindedly left the water source turned off overnight a few times, but thankfully, that's not nearly enough time for Mr. Cat to muster enough courage to face the scarecrow again. I guess there's nothing better than a cold splash of water to show a cat that its unwanted.

  • The Cats Stopped Using My Dad's Flower Bed as a Litter Box
    I bought this for my dad for Christmas. He has a neighbor with four cats and no litter boxes, so they started using his flower beds as their communal toilet. He just reported to me that after less than a month's use, he has found no digging in his flower bed. What's more, he's had the unit off for a few weeks and they're STILL staying away.

    He did note that the unit leaked a little, but he still gives it 5 stars. After trying everything from Cayenne pepper to synthetic coyote urine to spikey holly tree leaves (none of which worked), he was thrilled to finally have something that did the job. Yeah, it's expensive, but it was worth every penny to help lower his blood pressure (and save the lives of a few cats).

  • Scarecrow motion activated
    I've had this product for the last five years however my grandchildren got a hold of it and broke it so i bought two this time. It really keeps the deer out of my garden and is well worth the price. Highly recommended if you have an animal problem in your garden....more info
  • Not bad
    I noticed the stray cats come by less often now. The only negative reviews are occasional leaks and sensitivity to the wind (even after adjusting) but these issues are minor....more info
  • Very stupid machine
    This product does what it claims to, to a first approximation, but the motion sensor is very stupid. Towards the aggressive end of its sensitivity adjustment it goes off repeatedly into wind or when the pattern of shadows changes fast (perhaps the sun comes out from behind a cloud), but on the same setting it will let deer mosey to within one meter, straight ahead, before it will turn on. If the area you have to protect is tiny (a few square meters) then it's great. Deer jump a mile high when they're standing so close. But for larger areas it is nigh-useless.

  • Scarecrow Motion-Activated Sprinkler
    Up until the installation of the Scarecrow the deer had free range to "Munch" on any plant we had. We live in Eureka Springs, AR were the deer population are tremendous. I purchased two of the these subject sprinklers after reading the opinions shared at Set them up as described and they have been in place for the last 8-10 weeks and THEY WORK. We have not had one deer touch our plants since. We are seeing plants that we never have seen before because they never had a chance to grow. We hooked the sprinklers up to a timer that comes on at 7:30pm and goes off at 8:00am. We tried all the DEER OFF sprays, human hair tied to plants, moth balls, you name it nothing worked until the Scarecrow was installed. Try it I'm sure it will work for you...I'm impressed for sure. Satisfied customer.....Dave Smith, AR ...more info
  • Good with limits
    This motion detector sprayer worked every time when I forgot it was there and it sprayed me, and the dog also. It never did spray the birds I was trying to keep off my newly sowed lawn.

  • Repels the way it's suppose to.
    This was purchased to scare deer out of the yard. So's done the job beautifully. It's easy to set up and use. My biggest problem is remembering to turn it off and getting squirted myself. It also scares dogs out of the yard and occasionally a squirrel and birds. Amazon had the best price I could find on this item. It's well worth the money if you grow fruits and vegetables and don't want critters eating your garden. I gave this five stars but it should get ten stars....more info
  • A whole new world!!!
    The scarecrow has opened a whole new world of landscaping opportunites for me!!! For 2 years I have shared my home with about 20 deer. I love the animals and feed them twice a day in an area across my pond BUT they loved to have dessert in my landscaping. I have spent $$$$ trying all types of sprays with deterrent odors without success. An electric fence worked OK but looked so bad. The scarecrows (currently I am using 4 of them) have been working perfectly for the past month that I have had them out. The deer have learned NOT to approach these areas at all, as have my cats, the squirrels, and the rabbits...not sure about the armadillos yet. I have been able to plant flowers of my choice in planters on my stone patio, I have ROSES!!! I have a small garden. ALL of these areas are protected by my scarecrows and are flourishing. My deer still graze in my yard and certainly visit my feeder but we are cohabitating in a wonderful way. They have become part of my scenery that I now can enjoy. Several are now pregnant and two, I believe, are carrying twins. SO...the scarecrow has given me my landscaping back while preserving my privlege to view my wildlife. A SUPER DUPER WONDERFUL product!!!!...more info
  • So far, so good!
    Contech Electronics CRO101 Scarecrow Motion-Activated Sprinkler
    We installed this after losing big chunks of two coral bark maples to deer browsing this spring.

    They came back to taste the Eskimo Sunset maple, and only had a few leaves before the scarecrow scared them off! We're still messing with location/sensitivity, but the scarecrow sprinkler works great so far - we're very happy with our purchase....more info
  • It works just as advertised
    It's keeping the neighbors cats away from my bird feeder very effectively. I will try it this coming spring on the deer that eat my garden. Hopefully I can stop putting up my electric fence...more info

  • Works well, Just as described! Great for training/deterring any animal.
    I purchased this item to deter our dog from digging in a new planting bed. It works very well. Very adjustable, easy to set up, and the spray of water along with the noise associated with the sprinkler does well to get the dogs attention. No more garden problems... and its mobile so we can use it for other planters/areas.

  • I feel sorry for the mailman, not really. hehe!
    I bought this product because of random dog poop in my small front yard. I find it deplorable that people would let their dogs drop a deuce on anyone's lawn, much less a neighbor. I tried various things and nothing worked, the usual sprays, ammonia, and I even got to the point of taking the poo and shoveling it into the street, so the owner's would have to walk on the mess themselves. Frankly, I was getting tired of stepping in dog crap when mowing the lawn or just walking to get around the house.

    I installed the scarecrow in about 10 minutes and had it working great. Just trying to get the right spray projected in the right direction is probably the most time consuming but not difficult. I think it's a cool deterrent, I've already got a kick out of seeing people trying to bring their dogs to poop and once the scarecrow goes off the dogs looks baffled and the owner just walks away and keeps looking back trying to figure out what the hell just happened. I love it.

    I think the mailman is going to have to learn to walk around the motion eye if he wants to stay dry. I'd feel sorry for him but his kind of jerk in his right. I would highly recommend this to anyone with an annoying dog or critter problem. It works!...more info
  • Great product
    We couldn't be more pleased with the Scarecrow (which we call the Cat Blaster, CeeBee for short). No leaks whatsoever, range and sensitivity as advertised, plastic stake went into our hard Arizona ground easily, just be careful. Since the first night, when we heard it go off a couple of times, the offending cat has not appeared again. During the day we turn the sensitivity to "off" and also turn off the water. However especially in the hot Arizona sun, pressure builds up in the hose so it is a good idea to relieve the pressure occasionally one way or another (we have a bifurcating "wye" valve and just release pressure into the other hose). And be sure to use a quality hose, sustained pressure on a cheapo hose will ruin it quickly....more info
  • Pond Protected!
    We have used a scarecrow to protect my Koi for about 7 years - we are replacing the first one now as a valve broke. Set at eye level to a raccoon, it has kept my fish safe from numerous predators. The only creature not detured by it has been a heron - he thought it was a personal shower!...more info
  • Excellent Product
    I wouldn't have a garden if it wasn't for these sprinklers. Before I started using this product the deer were eating everything in my garden. Once I set up the sprinklers the deer ceased to be a problem. They deer appear to remember that the sprinklers are there and now keep their distance -- sometimes right on the periphery of the sprinkler's sensing range. I currently have four in use with two back-ups in the shed. Despite being a few years old and having been through some rough winters, mineral deposits, harsh sun, etc., they still work. Highly recommended for keeping deer and turkeys away. In my experience, cats are less deterred....more info

  • scarecrow the cat repellant
    My neighbor has 20+ cats and they roam free and use the neighborhood flower beds as their litter box, so I was reading about the scarecrow and decided to give it a try WOW!!! WHAT A PRODUCT

    The scarecrow does an excellent of job keeping the cats from using my flowerbed as a litter box , I turn it on at dark and I hear it going of sometimes through the night.
    After a weeks time I haven't turn on the scarecrow ( but I still leave it in place) and my flower bed is cat free, too bad for the neighbor he is entertaining the furry felines now

    even my indoor cat (fred) is getting some rest, he can finally look out through the day and wish he could go play with the birds not happening

    the scarecrow does exactly what it says and I recommend it and the neighbors get a laugh watching the cats run from the water

  • Scarecrow that shoots water
    So we stuck it in oour lawn facing our garden and had fun tresting it cuz we got ALL wet. We tossed the cats into the range too just to see if something smaller would set off the crow....YUP LOL. I just wish there was more sensing area (greater angle) so it would catch the critters (cats, birds, damn chickens) before the even got close to the garden. I still have to recultivate my garden and seed, that will be the true test. I sure hope the critters dont get use to it and come anyway, kind of like my rottweiler who loves to set it off and atck the water stream!
    She will chase it and try to drown in the stream. Maybe I'll buy one just for the dogs to play with in the hot Hawaii weather! OHHH i know I'll buy a third one to get the door solicitors too!!!!

  • Scarecrow
    This works great the only problems that bug me is the stake which comes with it is not worth a hoot. Better buy a piece of iron rod to hammer in the ground and then use a hose clamp to clamp the base to the iron rod. One other thing that I did not consider is...When the sprinkler system comes on, the motion dector goes to work too. The only way to turn it off is to remember to go out and do it before the sprinklers come on. Otherwise you will use a lot of batteries. Should have a timer on it....more info

The heron doesn't seem smart enough to get used to being sprayed by the water when he approaches the pond. Humans forget it's there, too, sometimes and I've been sprayed and drenched by it. Takes a 9volt battery, which in our case, needs to be replaced once a month or so, but it will depend on your level of usage....more info

They finallly agreed to send a new product, which we have not received as yet. I would not buy from this company again....more info
