Are Biological Methods the Best Methods for Controlling the Rabbit Population?

Phoenix, AZ, July 8, 2010 — As the rabbit infestation in Australia continues to cause wide spread damage to crops, the ecology, and the environment, some areas are considering drastic measures.

The State Government’s Cumberland Livestock Health and Pest Authority began trapping rabbits to test their immunity levels for calicivirus, commonly known as rabbit hemorrhagic disease, or RHD. They are hoping to find little resistance to the disease, so they can release it into the rabbit population as a way to reduce rabbit numbers.

Environmental conditions also need to be favorable for a successful viral release, specifically, an increase in the number of mosquitoes and flies, which will aid in the spread of the rabbit-killing calicivirus.

There are a growing number of residents outraged by the latest government measures to curb the rabbit population and, especially, the devastation it could potentially bring to the area. Mainly those with pet rabbits have been most outspoken against using calicivirus, as their pet rabbits are at risk of contracting the virus.

Is there a better solution to the ever-increasing rabbit population instead of eradicating thousands of rabbits? What are the alternatives? Local property owners protect their land from rabbit damage by installing fences and using rabbit repellent. The most effective protection comes from a combination of both methods.

Rabbit fences should be made from chicken wire, be 6-8” below ground, and 36” high. Once installed, rabbit fences should be monitored regularly for any signs of breaching. Should a rabbit get through, damage to the area can be significant. In addition, the fencing should be replaced often, once every few years, depending on how the chicken wire holds up against the weather conditions of the area.

The most effective rabbit repellent targets the keen sense of smell of rabbits. Putrescent egg is considered the best ingredient at repelling rabbits because it mimics the smell of decaying protein, which registers to rabbits as the possibility of a nearby predator, causing them to flee the area. Organic rabbit repellent is recommended as it can be used in gardens and does not add chemicals to the environment. Those rabbit repellents with the OMRI logo on the label have been certified organic and can be used on plants intended for human consumption.
