Frequently asked questions
When does flea season start in Greenville?
Around mid-February 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 Greenville different from the rest of South Carolina?
Somewhat. That's about 2 weeks later than the South Carolina statewide estimate for this climate. The statewide page averages several stations across South Carolina; this page uses the normals recorded at GREENVILLE DWTN AP.
Do dogs in Greenville 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 South Carolina are typically active year-round, a longer window than fleas get.
