Frequently asked questions
When does flea season start in Fort Wayne?
Around early April in a typical year, once local averages hold around 50°F. A warm spring pulls it earlier — prevention shouldn't wait for the calendar.

Somewhat. That's about a week later than the Indiana statewide estimate for this climate. The statewide page averages several stations across Indiana; this page uses the normals recorded at FT WAYNE INTL AP.
Do dogs in Fort Wayne 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.
