Puerto Vallarta, Jalisco, October 20, 2026 – Jalisco is reinforcing dengue prevention in cemeteries before Día de Muertos, but its statewide announcement does not confirm completed treatment in Puerto Vallarta.
Are the city’s cemeteries ready for families visiting November 1 and 2? Public sources reviewed for this article did not establish which local grounds have received treatment, their cleanup schedules, or their 2026 holiday opening hours. That information gap does not establish that work has gone undone.
The distinction matters for residents preparing to clean a family grave, bring flowers or accompany friends to a cemetery. Readiness includes mosquito control, usable paths and basic services, and clear arrangements for entering and leaving during busy visiting periods.
Puerto Vallarta’s five principal municipal cemeteries are 5 de Diciembre, El Progreso, Ramblases, Ixtapa and Las Palmas. In an October 31, 2025 report, officials described a month of cleaning, pruning, lighting work and rubbish removal at those sites.
That report also described signs identifying entrances, evacuation routes and bathrooms, plus water for families cleaning graves. Those details provide a useful benchmark for assessing this year’s preparations.
The current health campaign addresses another part of that work: containers where mosquitoes can breed.
Cemetery brigade leader Nayeli Salazar Vázquez explained how crews work around individual graves, as previously reported.
“We remove the dried flowers and apply the preventive treatment,” she said in Spanish. She identified the product as Vectobac, which crews apply to water-holding containers to control mosquito larvae.
The health department’s recommendations include scrubbing flower vases, removing unused containers, and replacing vase water with damp sand. Its concern is the accumulation of water in objects left around graves, where the dengue-transmitting Aedes aegypti mosquito can reproduce.
The cemeteries include Guadalajara Nuevo, Mezquitán and Huentitán. The announcement also refers broadly to work in other regions of Jalisco.
For visitors to 5 de Diciembre, there is some current practical guidance. The Puerto Vallarta tourism board’s October 14 visitor guide recommends arriving early, wearing a hat and sunscreen, staying hydrated, and leaving glass containers and alcoholic drinks at home.
The guide describes November 1–2 as the traditional gathering days at the cemetery. Before arranging a taxi or coordinating a family visit, confirm the cemetery’s opening hours with the administration.
The city’s wider celebration runs October 31–November 2, as Vallarta Daily’s report on Día de Muertos plans covers. Families preparing flowers for a grave can act on the health guidance now: use damp sand in the vase and take away unused containers that could collect rainwater.
