The granola was gone, shredded paper scattered, another silent invasion in a Tahoe vacation rental. This summer, the picturesque mountain destination isn’t just battling over-tourism; it’s facing an unprecedented rodent uprising that’s leaving locals and visitors alike on edge.

The Year of the Mouse

Local pest control experts like Sergio Arias from Tahoe Pest Management are calling 2025 “out of this world crazy” for rodent activity. Where he typically managed 20 calls per month, Arias is now fielding 50-60 weekly, pulling up to 70 rats from a single house. “I’ve never seen anything like it,” he admits.

Hardware stores across North and South Lake Tahoe are experiencing a trap shortage that echoes the rodent invasion. At North Shore Ace Hardware, assistant manager Maurice Jacques reports locals are buying up to 15 traps at a time, with inventory depleting within days.

Why the Rodent Explosion?

Experts suggest the late spring’s unusual snowstorms and abundant moisture might be creating perfect breeding conditions. Vacant vacation homes, a Tahoe staple, are becoming unintentional rodent sanctuaries. “These mice start reproducing prolifically in these homes and start affecting the neighbors,” Arias explains.

While some are calling this a potential once-in-a-decade event, wildlife researchers caution against definitive claims. The connection between climate and rodent populations remains complex and somewhat unpredictable.

What This Means for Tahoe

For now, Tahoe residents and visitors should remain vigilant. Check your rentals, seal potential entry points, and maybe pack an extra set of mouse traps, just in case. This isn’t just a pest problem; it’s a vivid reminder of how quickly nature can reclaim its territory in our mountain playground.
