How many deer live in Fairfax County? top of page
""      Deer live in just about every area of the County. Although it is not possible to know exactly how many deer live within the County's boundaries, population studies are conducted on an ongoing basis. These studies indicate that as many as 400 deer per square mile can be found in western parts of the County and that as many as 100 deer per square mile can be found within the County's urban sections. Science tells us that ideal deer densities are 15-20 deer per square mile of suitable habitat. Unfortunately, many of the areas in which large deer herds are found contain low levels of suitable habitat due to the large number of deer and deer overbrowsing. Stream valleys and natural wooded areas of the County that have little undergrowth and relatively few native, hardwood seedlings are likely populated by a large number of deer.

How much of a driver safety hazard are deer? top of page
     Deer pose a significant safety hazard for drivers in many areas of the County. In fact, the incidents of deer/vehicle collisions in the County are higher than collisions resulting from alcohol. Although the County does not have records of all deer/vehicle collisions, approximately 1,060 deer died in 1999. This figure represents only a portion of the number of white-tailed deer estimated to have been injured as a result of collisions and is a decrease of 6% from the previous year.

     Vehicle damage, personal injury, and death have resulted from these collisions. Preliminary survey data from areas of the County where deer/vehicle collisions are high indicate that as many as 60% of households have experienced hitting a deer in a vehicle. Most collisions occur in the fall when breeding season causes deer to be more active. In order to avoid hitting a deer, drivers are encouraged to watch for deer especially at night and in the early morning hours.

How fast are the deer producing? How many do we have and how many is too many? top of page
     A healthy female deer may produce two fawns per year. In a habitat where there are no natural predators, a white-tailed deer population can double in two years. An overabundance of deer is demonstrated by:
  • Increasing incidents of injury and death to citizens and deer as a result of deer/vehicle collisions
  • An over-consumption and loss of natural food supply
  • Damage to domestic and native vegetation on public and private lands
  • Declining health in the deer population
     The Virginia Department of Game and Inland Fisheries has estimated that Fairfax County has anywhere between 15 and 419 deer per square mile. Fairfax County’s Integrated Deer Management Plan indicates that a healthy, viable deer population within Fairfax County has been determined to be comparable to pre-settlement conditions when there were 8-15 deer per square mile.

What does a deer eat? top of page
     White-tailed deer feed primarily on leaves, buds, twigs and nuts. They also enjoy ornamental plants in residential communities such as hostas, daylilies and azaleas. An average deer eats between 5-8 pounds of plants a day.

What is a browse line? top of page
     A browse line is a sign that there is an overpopulation of deer. Trees and shrubs look like they have been trimmed or clipped of all their leaves often up to a height of five feet. There is also very little vegetation on the ground. When no new growth is permitted, young trees are not produced and the habitat for nesting forest birds and other wildlife is destroyed.

How can I keep deer from eating my garden and the shrubs and flowers in my yard? top of page
  • While some plants may be less enjoyable to deer, the food palette of urban deer is evolving and expanding. Also, damage will vary depending upon availability of other food choices.

    Consult local nurseries regarding plant varieties not favored by deer. Some of these include:
    • Common Boxwoods
    • Colorado Blue Spruce
    • Red Osier Dogwoods
    • Scots Pine
    • Common lilac
    • Ornamental Grasses
    • Tarragon and wormwood
    • Virginia Bluebells
    • Forget-me-nots
    • Carnations
    • Daffodils
    • Lilly of the Valley

  • Install fences. A resource for information on fencing options can be found at: http://www.oznet.ksu.edu/library/wldlf2/c728.pdf.

  • Some residents have found it helpful to hang wrapped bar soap in the affected area. The brand of soap does not appear to make a difference. Hotel style bars work as well as full sized bars of soap.

  • Keep dogs present in the area.

  • Contact local nurseries for information on deer repellent products currently coming on the market.

    Note: While human hair may have been an effective deterrent in the past, may residents have found this technique is no longer effective. Urban deer have become comfortable co-existing with humans. Wild animals become acclimated to deterrents. A varied program with several components will be more effective than a single preventive method.

Because of the loss of habitat due to all the construction in the County, wouldn’t it be a good idea to feed the deer so they don’t go hungry? top of page
  • The response of the deer herd would be an increase in the birth rate. Therefore, by feeding deer, you are contributing to the current problem.

  • Deer become reliant when fed. Therefore, if you begin to feed them, you should continue. The average deer consumes five pounds of food per day.

  • With group feeding comes the potential threat of the transfer of disease.

Who should I call if I find a dead or injured deer on the road or on my property? top of page
  1. If the deer is on the roadway, right-of-way (15 feet from the edge of the pavement), or sidewalk, contact Virginia Department of Transportation at (703) 383-8368.

  2. If the deer is on Fairfax County parkland, contact Fairfax County Park Authority, Park Operations Division, at (703) 324-8591.

  3. If the deer is on private property, the property owner is responsible.
     Please note: If an adult deer is injured to the point of being approachable, it cannot be rehabilitated. Contact Fairfax County Police Department non-emergency number at (703) 691-2131.

If I hit a deer am I supposed to stop and wait until help arrives? Who do I call? top of page
     You are not required to stop if you have an accident with a deer unless it involves another vehicle, pedestrians or personal property other than your vehicle. However, if the deer is alive and in the roadway, please call the Police non-emergency phone number to report it (703-691-2131). If after a deer related accident there is damage to your car, contact the Police non-emergency number to report it and your automobile insurance carrier.

Should my family be concerned about contracting Lyme disease from deer ticks picked up in the County? top of page
     Fairfax County Health Departments reports an increasing incidence of Lyme disease. However, it is estimated that only 1% of deer ticks are infected. If you have additional questions, you may contact the Health Department at (703) 246-2433.

Why isn't the County pursuing methods to reduce deer fertility?
top of page
     Immunocontraception as a method of birth control is being used to control deer population among confined herds on an experimental basis. This method consists of injecting female deer with a protein or hormone released through darts or biobullets. To be effective, two injections must be administered during the first breeding season followed by a booster every year. The County is not using this method at the present time for four main reasons:
  1. To date, there is no known technique to locate, approach and dart a majority of the female deer in a free ranging herd. Each deer would also have to be tagged for identification purposes to avoid accidental multiple doses. Darting of deer would need to take place on an annual basis through the County.

  2. The County’s use of this experimental method requires partnering with a university or other research organization to test this method and no partner has been identified at this time.

  3. The effectiveness of this method is currently limited to confined herds.

  4. There are no State policies or regulations that would allow the County to use this method non-experimentally.

What about addressing the County's deer population by relocating deer to other areas of the State? top of page
     Relocating deer is not considered a viable option for the following reasons:
  • The State will not issue permits for relocating deer.

  • The mortality rate, during the capture as well as after the capture, is significant.

  • The cost (tens of thousands of dollars) of relocating deer is prohibitive.

  • Most of the eastern United States is experiencing problems related to high deer populations. Therefore, there is no area to which deer can be transported.

How do roadside reflectors work and have they been effective? top of page
     Roadside reflectors are an experimental technique being used to keep deer off of roadways. Although it is not yet known how effective they are, they are designed to alarm deer in the vicinity of a roadway by creating a barrier when light from headlights bounce off them, keeping deer off the roads. Roadside reflectors have been installed as part of a pilot program along Telegraph Road in Fairfax County. Their effective value remains inconclusive at this time.

Has any thought been given to releasing wolves or coyotes in Fairfax County to naturally control the deer herds? top of page
     Restoration of large predators is not a viable option for deer herd control in an area with the level of urbanization found in Fairfax County.

     Large predators, such as wolves and mountain lions, need large expanses of undeveloped natural habitat. This is one commodity no longer found in Northern Virginia. If public support existed for a plan such as this, it is very unlikely that a large predator would survive the urban hazards or choose to remain in Fairfax County.

     Although we are an urban County, bears wander into Fairfax County each year and bobcats still exist in some areas. Coyotes are believed to be present in the County as well and will likely become more common in the future. In the majority of areas where both deer and coyotes exist, coyotes do not demonstrate an ability to limit the growth of the deer herd

Is hunting deer on my property in Fairfax County possible? What do I need to do? Who do I contact? top of page
     A hunting registration for firearms use can only be approved in those areas of Fairfax County designated by the Board of Supervisors. A minimum land parcel of twenty acres is required. The 20 acres need not be under single ownership, but must form a single tract. Hunting on posted property requires written permission of the property owner; hunting on nonposted property requires verbal permission of the property owner. Contact the Department of Animal Control at (703) 830-3310 for details.

     There is no minimum acreage requirement for bow hunting. However, archers must have the permission of the property owner.


Do you know of any organizations that will help to take care of my deer problem? top of page
     There are archery groups in Fairfax County that may provide assistance. Consult the web for various sites listing bow-hunting organizations in Virginia. For information regarding Deer Kill Permits, contact Game & Inland Fisheries.
