- Biological Control
Poisons such as Sodium Monofluoroacetate (1080) are used in dry baits, which are much more effective on foxes than on other animals, such as feral cats, as foxes are mostly scavengers.
Foxes were introduced for hunting as a recreation. But now, due
to animal rights organisations having a strong influence on
fashion trends, fur and hunting are no longer fashionable and
the price of fur and fur industry is unstable.
ThinkQuest 2003Immunocontraception is in the experimental phase, currently. If it is accepted and adopted by the Australian Government and the CSIRO, it is expected to decrease the fox population by approximately 80%. The effect would be achieved by inoculating viral vectors (organisms that carry disease from one creature to another) with the immunocontraceptive. Because these vectors must consume blood frequently in order to live, the immunocontraceptive that they carry would ultimately be passed to the foxes when the vectors prey upon these creatures, thereby resulting in sterilisation among a large proportion of foxes in Australia. But in order for this to work the vector must infect a large percentage of vixens (female foxes). But with foxes, unlike rabbits and cats, the immunocontraceptive could be delivered through baits, like poisons, as these scavenging vermin take to baits.
