Frequently asked questions
When does flea season start in Reno?
Around late March in a typical year, once local averages hold around 50°F. A warm spring pulls it earlier — prevention shouldn't wait for the calendar.
Is flea season in Reno different from the rest of Nevada?
Somewhat. That's about 2 weeks later than the Nevada statewide estimate for this climate. The statewide page averages several stations across Nevada; this page uses the normals recorded at RENO TAHOE INTL AP.
Do dogs in Reno need prevention outside flea season?
Yes — vets recommend year-round parasite prevention regardless of the local calendar. Indoor fleas ignore the weather entirely, and ticks in Nevada are typically active late January to mid-December, a longer window than fleas get.
