The brown tree snake is a nocturnal, rear-fanged colubrid, possessing two small, grooved fangs at the rear of the mouth.
Due to the placement of the fangs and their grooved rather than hollow architecture, the venom is difficult to convey into a bite on a human, and thus is only delivered in small doses.
The venom appears to be weakly neurotoxic and possibly cytotoxic with localized effects that are trivial for adult humans; serious medical consequences have been limited to children, who are more susceptible because of their low body mass.
 The snake has been reported as aggressive, but is not considered dangerous to an adult human.
The venom seems to be primarily used to subdue lizards, which can be more easily positioned in the rear of the mouth for venom delivery.
