However, and regardless of what Mr. Eimermacher says, some boomslangs, regardless of what they are kept in, will rub and rub and rub until they have just about no nose left.
Actually, nothing could be further from the truth. Nose rubs are a common problem in Dispholidus, because they are commonly kept in unsuitable conditions. There are several key factors to Dispholidus husbandry, including space, shelter, and a particularly low stress environment. Like many fast arboreal species, Boomslangs are nervous and easily stressed. Conventional housing methods that are typically applied to many species do not work well for Boomslangs. Fresh imports are especially nervous and require great attention to detail with regard to their housing.
Relative to their size, they require larger enclosures than many species that will keep them from frantically rubbing their nose in a desperate attempt to escape their confinement. In fact, some specimens require enclosures that are far larger than most keepers would deem necessary for a species of that size. The second key factor is the shelter. Due to their nervous nature, Boomslangs will often dive for cover when approached with haste, and may zoom from one end of the enclosure to the other in wild panic to escape the perceived threat. In order to provide them with an adequate captive environment, their setup must contain numerous hide spots and retreats, as well as an arraignment of branches and plants. In the wild, Dispholidus utilizes branches and plants for shelter, and this concept can be very successfully applied in captivity as well. Keep in mind that there is a significant difference between having a few branches and plants in the enclosure, and actually providing a densely-planted, arboreal environment.
Specimens that are rubbing their noses on cage furniture are displaying classic symptoms of stress, which can certainly be rectified by providing the appropriate conditions. I have worked with Boomslangs for some time, visited their natural habitat and studied them in great depth. At times, I have had as many as 17 specimens in my collection, including juveniles, subadults and adults. I have also raised several hatchlings and acclimated many fresh imports. With the housing conditions described above, even the most notorious nose-rubbers will calm down and eventually become well adapted to a captive environment.
If anyone has trouble with nose rubs in Boomslangs, please feel free to contact me to help solve this problem. The claim that some specimens simply rub their noses off for no apparent reason is obviously irrational, since this is a problem that is strictly limited to captive situations, and can definitely be rectified if the appropriate conditions are provided.
