Crow Control: How to Keep Crows Away from Buildings, Garages, Houses, Farms, and More

Got a Crow Problem?

Crows are a problem for all types of properties, from parking lots to agricultural fields, to suburban homes and even buildings in urban areas. Flocks of crows create a lot of noise, leave messy droppings that can spread disease, strew garbage around, and cause property damage to buildings and landscaping. Crows are also major agricultural pests that damage crops, particularly corn, peanuts, sunflowers, pecans, and various fruits. In some instances they prey on livestock, such as newborn lambs or goats.

Crow Control Solutions

Get rid of food sources to discourage crowsA good first step to deter crows is to remove potential food sources. Secure trash cans, remove bird feeders, and bring pet food containers inside. If that tactic doesn’t work, you may need to take additional steps to get your crow problem under control.

With the right crow control products, you can solve your crow problem for good, the first time. At Bird Barrier, we’re here to help you find exactly what you need for your situation—whether it’s for a commercial building or your home. We offer expert support from product selection advice and  our installation videos to our top-of-the-line customer service.

Crows are intelligent and determined birds with good memories and the ability to use tools. Crows have also been known to remember the faces of their enemies and hold grudges. To truly get rid of crows, and keep them away for good, you’ve got to outsmart them. The most effective approaches to crow control are:

  • Exclusion netting like StealthNet
  • Ledge deterrents like Bird-Shock or Dura-Spike
  • Audio, Visual, and Taste Deterrents

Scaring Crows Away: Audio and Visual Deterrents

Visual and audio deterrents are a form of harassment techniques designed make crows uncomfortable enough to migrate to another area. Crows are much more likely to vacate a new roost site rather than an established one so it is important to act quickly after they arrive.

It is possible to drive away large flocks of crows and other blackbirds with audio and visual scare devices such as the Bird Gard unit combined with visual scare devices like Scare Eye Balloons, Octopus, and Flash Tape.

To maximize effectiveness, hang visual products in trees before commencing a noise campaign.

Bird Netting to Keep Crows Away from Buildings and Gardens

For small gardens and orchards, four-inch or smaller flexible mesh bird netting will keep crows out. For other structures and buildings, our StealthNet® Bird Netting can be used to deter crows from any enclosed or semi-enclosed area. StealthNet Bird Netting is available in three mesh sizes, all of which will deter crows: 3/4," 1-1/8", and 2".

1. What is the bird pressure?

  • Heavy: Crows are nesting and extremely committed to the site.

  • Light: Crows are hanging out at the site from time to time, but are not committed.

  • Roof peak
  • Trees

What About Killing or Trapping Crows?

Local laws that regulate the hunting, killing, or trapping of crows vary from state to state. Nationally, crows are protected under the Migratory Bird Treaty Act, which is enforced by the U.S. Fish and Wildlife Service. However, under federal regulations, crows can be killed without a hunting license or permit when caught threatening or damaging trees, agricultural crops, livestock, or wildlife.

Lethal means of control can also be taken legally when crows are concentrated in roosts so large that they constitute a nuisance or pose a health and sanitation hazard. However, it should be noted that shooting is not generally considered to be an effective way to manage crow populations. Also, if you are considering lethal means, keep in mind that crows are social birds and the flock is in constant communication, which can make hunting and trapping very difficult.

Effective bird deterrents and repellents are not only much more humane, they are also usually the best solution, without negative environmental effects, dead birds to clean up, or public relations problems.

Crow Identification and Behavior

Getting to know more about crows can help you better understand and effectively solve your crow problem.

Identifying Crows

There are three main species of crows found in the United States, the large American crow, found all across North America, the smaller Fish crow found in the Southeast, and Northwestern crow, which is generally only found on the Pacific Coast from northwestern Washington up through southern Alaska.

The American (or Common) crow is coal black from bill to the tip of the wing and claws with a metallic violet gloss on body and a blue-violet or green-blue gloss on wings. Adults have black eyes while juveniles have blue eyes. It grows to approximately 17 to 20 inches long with a strong, stout build and a compressed bill.

The Fishing crow and Northwestern crow are smaller, darker versions of the American crow. It is incredibly difficult to tell species of crow apart visually.

Info on Habitat, Diet, Nesting, and Breeding Patterns


Crows thrive in a wide variety of habitats though they prefer to be near farms, fields, and grassland for foraging, and woodlands and forest edges for roosting and breeding. They have adapted quickly to suburban and urban environments, roosting in city parks as well as on billboards, power lines, telephone poles and other manmade structures.


All crows are omnivores. They will eat pretty much anything they can find, including garbage, carrion, insects, seeds, grain, berries, fruit, spiders, snails, earthworms, frogs, small snakes, mice, shellfish, and even the eggs and young of other bird species. They’ve even been known, in rare cases, to hunt the young of other species, such as newborn lambs or goats.

Crows are opportunistic and always on the lookout for new food sources. They will scavenge, steal, and hunt anywhere they find food. They feed mostly on the ground, which is why you might see unsecured trash scattered around on a property near crow roosting spots. Though they do provide some beneficial insect hunting on farms, crows often cause agricultural damage by eating newly planted seed or vulnerable early crops, especially corn. They can also cause significant damage to tender fruits and vegetables.


Crows are committed nest builders. Crows typically build nest sites in the forks of tree branches or large shrubs between ten and seventy feet above ground. They rarely build nests on building ledges. Crow nests look like large baskets made of sticks, twigs, and mud with shredded bark, grass, feathers, or other soft material as liner.

Breeding Patterns

Crows have one or two broods a year, averaging four to seven eggs per brood. Incubation takes eighteen days with a four- to five-week fledgling period before the young leave the nest. The eggs range from pale bluish-green to olive green or greenish-brown with splotches of brown and olive-gray.

Migratory Patterns

Northern crows will fly thousands of miles south during the winter, while southern birds stay put year round.

Flocking Behavior

One notable characteristic about crows is their flocking behavior. In fall and winter, they will move to better feeding areas where they will coalesce into massive feeding flocks. These feeding flocks in turn, join up with other flocks at night to form enormous communal roosts numbering from a couple thousand to tens of thousands.
