Trapping is central to the integrated control program to deter brown tree snakes from entering the outbound cargo 1ow from Guam. Trapping brown tree snakes is effective, but labor intensive. Increasing inter-trap spacings without loss of e3cacy could substantially increase the e3ciency of efforts to prevent dispersal of this species. Inter-trap spacings of 20, 30 and 40 m along perimeter trap lines were compared using recaptures of tagged brown tree snakes. No differences were found among the different spacing distances for the distribution of recapture times. The results indicate that for some situations, snake trapping may be extended or made more e3cient by increasing the distances between traps.
