Frequently asked questions
When does flea season start in Evansville?
Around mid-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 Evansville different from the rest of Indiana?
Somewhat. That's about 2 weeks earlier than the Indiana statewide estimate — city warmth and lower elevation add up. The statewide page averages several stations across Indiana; this page uses the normals recorded at EVANSVILLE REGIONAL AP.
Do dogs in Evansville 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 Indiana are typically active early March to early December, a longer window than fleas get.
