Crows and the Problems They Cause

Many times it takes a wide variety of methods and plans to remove crows from unwanted areas, where they can damage crops, spread disease and cause scores of problems to humans. They are a serious problem for airport areas and other businesses. They congregate in numbers from hundreds to thousands, dropping waste on everything in their path.

A crow is a bird that is completely black, with black eyes. Adult crows have a violet tint to their feathers. They are distinctive from the sound they make which sounds like, “caw-caw.” The crow looks very much like the Raven and is often mistaken for them, but the crow is smaller of the two species. However, the crow is a respectable size from 17” to 21” long. Also, a Raven will soar more often and has a uniquely shaped tail. This is why in flight; it is easier to tell the Raven from the Crow.

Bird Damage 

As every farmer knows, crows love corn. Corn is their main source of food. That is why you will often see scarecrows in corn fields. This may work at first, but soon the crow will learn he has nothing to fear from the strange being in the field and will return to the field to eat. Crows are not picky eaters and will gladly destroy many types of crops quickly if gone unchecked. In fact, a crow will eat almost anything. They are part of a select group of birds that are able to hunt, pirate and scavenge for food. Crows do help the farmers by eating June Bugs, mice and even snakes; but the benefit is usually suppressed by the damage the birds actually cause on their own.

Another major concern regarding crows is they will consume the eggs and even hatchlings of waterfowl and pheasants during nesting times. They will often scavenge farms and steal food from pigs. The droppings of crows have been linked to spread of swine diseases. Even their nesting areas cause health concerns for humans. Often the huge numbers of crows nesting in a house, farm, or barn will allow fungus to grow in the nest. This is yet another opportunity to spread illness.

Crows natural enemies are the Owl and the Hawk. Some people try to put out decoys to scare off the crow, with limited success. Noise makers are also used with some success. However, as stated before; crows are smarter than even pigeons and geese. They soon figure out the methods being used. For that reason, it is more cost effective and safer to use a professional to take care of crows and the problems they create. Crow control is not easy and requires know-how and experience. Not controlling a crow problem is very costly in damage, expense to buildings, livestock and airports and in the health and well being of other birds, animals and people.

Control Options Strategies

  • Installation of ¾” to 2” mesh size bird netting

  • Bird Spikes

  • Tension Wires System

  • Electrified track systems

  • Building modification and alteration

  • Sounds Units (various options)

  • Visual Scare Devices (various options)

  • Taste Deterrents

  • Thermal Fogging of trees and landscaping

When determining a crow control plan, it is important to take several factors into consideration: 


  • How long has the crow problem been going on for?

  • How severe is the crow problem?

  • Available food and water sources nearby?

  • How much will it cost to resolve the bird problem?

  • What type of damage are the birds causing?

  • Are there any liability issues due to the bird infestation? 

Crows will often roost in packs of thousands. This is to protect them from any predators that may be around. They will roost near a major food source. They normally will travel within 12 miles or so of their food. However, they will sometimes travel up to a hundred miles to feed and then will return to the roosting site in the evening. This cuts a wide path of destruction. Crows are territorial. They will come to the assistance of crows from another pack if they are in danger or are being threatened.

It is wise to know the law when attempting to deal with crow problems. Crows are protected by the Federal Migratory Bird Treaty Act. This is a federal act resulting in a treaty signed by the United States, Mexico and Canada. Never the less, there are built in protections that will allow you to handle the crow situation. A bird control professional will know all the laws and regulations to allow ratification of the crow bird problem in a safe and human manner.

The methods needed to take care of the crow overpopulation of an area must be designed for that particular area and the particular situation surrounding the infestation. There is no “one size fits all” approach. There is no simple answer. The crow is a formidable challenger, with certain legal rights.
