Discovery in the Attic
In late July 2025, staff at the Grand Teton Lodge Company identified a significant bat infestation in the attic of several cabins at Jackson Lake Lodge. The discovery followed weeks of guest reports about bats inside their rooms. Because bats are well-documented carriers of rabies, the presence of the animals in overnight accommodations immediately raised alarms about potential exposure.

Rabies, while rare, is almost universally fatal once symptoms appear. Bites from bats can be particularly insidious, as they may occur without waking a sleeping person or leaving obvious marks. That risk led authorities to treat the infestation as a public health emergency, even though no bats captured at the site have tested positive for rabies to date.
Coordinated Health Response
The Wyoming Department of Health launched an extensive outreach campaign, attempting to contact every individual who stayed in the affected cabins during the summer season. Guests span numerous states and countries, complicating notification efforts and requiring coordination with other health agencies.
Officials are recommending post-exposure prophylaxis for those who may have been at risk. This treatment, which combines a rabies vaccine series with immunoglobulin injections, is highly effective at preventing the disease if administered promptly. The emphasis on speed reflects the grave consequences of untreated infection, which causes progressive neurological deterioration.
The cabins were closed on July 27, with no plans to reopen until the buildings are declared safe. Lodge management has not yet provided a timeline for repairs or remediation, as removing bats from structures often involves specialized wildlife control and sealing entry points to prevent recurrence.
Ripple Effects on Tourism and Park Management
The incident’s timing at the height of the park’s tourist season has magnified its impact. Grand Teton National Park is one of Wyoming’s most visited destinations, drawing hundreds of thousands of travelers each summer. The closure of the cabins represents both a logistical setback for visitors and a financial loss for the Grand Teton Lodge Company, which depends on peak season revenue.
Beyond immediate tourism losses, the infestation has sparked renewed attention on how wildlife and human infrastructure intersect within protected lands. The National Park Service, working alongside lodge management, has issued safety advisories to guests and committed to reviewing protocols for both wildlife monitoring and building maintenance.
Experts suggest the event could shape future regulations for national park
accommodations, requiring more regular inspections of structures for wildlife entry points. Such measures would add costs but could reduce the likelihood of similar disruptions in the future.
Ongoing Caution
Even though captured bats have tested negative for rabies, health officials stress that uncertainty remains, as not all bats could be caught and screened. Until the risk is fully resolved, outreach and treatment recommendations continue.
For park visitors, the episode underscores the often-overlooked reality that even in developed facilities within national parks, encounters with wildlife can carry serious health risks. For public health agencies, it is another test of cross-state communication and rapid response in containing potential zoonotic threats.
