I've been working in a backyard bird feeding store for several years now. The three most common things people ask me are how to get rid of squirrels, how to get rid of raccoons, and how to get rid of crows. The first two are actually pretty easy. Getting rid of crows, on the other hand, is a little trickier. The problem is that crows are so friggin' smart. Smarter, actually, than a good share of the people I know. Prettier too. I know this doesn't seem to speak too highly of the people I surround myself with (contributers to this website excluded, of course), but darn: numerous studies have been conducted with crows, and these birds have shown the mental capacity to solve problems and even use tools.
So yeah, crow birds are impressively smart and crafty little devils. So what? Well, the smarter they are, the harder they fall. Especially if there's food involved (which is oftentimes the reason they're hanging around your yard.) They also happen to be very persistent and extraordinarily stubborn. Keeping this in mind, the best thing you can do to get rid of crows is to be even more persistent and more stubborn than they are. It's the only way you'll win. So read this article, buckle down, and start a stiff bird control strategy against crows.
Remove any food/water sources. As mentioned above, if you have crows hanging around your place, there's a pretty good chance they're there because you (inadvertently) lured them there with food. Remove all things that crows might find edible. This includes bird feeders/baths and dog and cat kibble and water dishes. You will also need to make sure to put all trash in tight-lidded trash bins. Crows can and do tear open plastic garbage bags. Unfortunately, they like compost too. Either cover it somehow or bury edible items under grass and leaf clippings. Keep an eye on what it is they're eating; you may even need to cut down berry bushes and fruit trees.
Make loud and scary noises. Make the crow or crows return your sentiment of dislike. Every time you see them out there, make a racket and direct it towards them. Get out there and start yelling obscenities. Yeah, your neighbors will probably start thinking you're a whack job, but who cares. Along with your yelling, clap your hands, bang pots and pans together, or set off fireworks. Above all, be consistent. Do it every darn time you see them, or it won't work.
Set out devices designed to scare crows off. The most common of these, of course, is the scarecrow. I know it sounds dumb, but it works. Buy one or make your own and dress him in bright colors. Other good scary devices include fake owls and fake snakes. Some people even make their own crow deterrents by stringing up aluminum pie tins or blank CDs to flutter in the wind. Also, most bird and garden stores carry Scare Tape. This is nothing more than a spool of reflective ribbon that hangs and dances in the breeze.
Switch up your scare tactics. I simply cannot stress this enough. Crows are extremely smart. If you attempt to use just one of the bird pest control methods mentioned above, the crows plaguing your yard will quickly get used to your feeble attempts and realize that they are not in any real danger. The best thing you can do is to use as many tactics as you can. Don't use them all at once, though. Use a couple different methods for a few days, remove them, and do something different. Switch things around and pick different locations. I know it sounds like a pain in the ass, and it is, but it's better than waking up to crow-cawing every morning for the rest of your life.
Blow 'em away. Killing crows should always be left as an extreme last resort. While I do not condone this method, sometimes you do what you gotta do. Crows can be destructive. They'll peck at things, poop all over the place, and sometimes even eat your garden. Crow hunting is legal in most states, and if it's not the proper season but you can prove they are causing damage to your property, you can sometimes even get a special permit to kill crows. Just make sure to know the laws in your region. As far as the authorities are concerned, ignorance is not an excuse.
Crow Deterrents & Crow Repellents
Aside from the basic and relatively inexpensive things you can do for bird control, there are a number of products on the market that are designed to deter, repel, or remove crows completely. Granted, some of them are a little more costly, but if customer reviews are to be believed, they are well worth it. The following is just a small sample of a few of the most highly recommended of these.
Ultrasonic crow repellent. These systems are designed for outdoor, year-round use and use ultrasonic (you can't hear them) sound waves to annoy, repel, and frighten a wide variety of birds, including crows. Look for Ultrason X.
Bird netting. Bird netting is fantastic for folks who have issues with crows eating their gardens or berry bushes. It's nothing fancy, but it works wonders. It's easy to install (stakes and staples), is quite strong, and will last you many seasons.
Bird Xpeller Pro. This handy little crow deterrent works through the use of recorded distress signals. When crows hear the distress signals (actual recordings) they get the idea that your yard is an uninviting and unsafe place to hang.
Bird spikes, also known as mechanical perch repellents or roost stoppers, are stainless steel or polycarbonate rows of spikes that can be affixed to surfaces where crows have a habit of roosting. It doesn't hurt the birds; it just makes it nearly impossible for them to sit in places where the spikes have been attached.
Crow traps. A crow trap can either be purchased or made at home. If you want to make your own, just Google "homemade crow trap" or some variation on the theme. You'll find what you're looking for. There really isn't much to say about crow traps. They're traps. They catch crows.
