The U.S. Department of Agriculture’s Wildlife Services (WS) program and partners from the Department of Defense (DoD), Department of the Interior, and the Guam Department of Agriculture will soon begin a series of aerial bait broadcasts to reduce the population of invasive brown treesnakes on Guam. Starting in September and continuing for approximately 16 months, WS experts and their partners will deploy acetaminophen-treated dead mouse baits attached to biodegradable corn starch streamers designed to snag onto branches in the dense tree canopy where the snakes feed. The baits will be dropped from helicopters. The goal of the $1.3 million project is to significantly reduce the brown treesnake population at two, 55-hectare (135-acre) jungle sites within the DoD’s Anderson Air Force Base.  The results of the project will be documented and used to guide future efforts to control or eradicate the snake population island-wide.

To offer the news media an opportunity to observe these activities and learn more about the brown treesnake issue, a media event is scheduled for Tuesday, October 1, on Guam (Specific location TBD).  A required orientation session with agency representatives will begin at 8:00 am local time.  Demonstrations of the aerial bait drop, bait manufacturing, and other brown treesnake management activities will follow the orientation meeting and are expected to conclude by 1:00 pm.  

Space for media representatives is limited and requests will be accommodated on a first-come, first-served basis. To participate, please contact Gail Keirn at 970-266-6007 ( by September 17, 2013 to ensure adequate time to obtain security clearance.
