Frequently asked questions
When does flea season start in Kansas City?
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 Kansas City different from the rest of Missouri?
Not meaningfully — Kansas City tracks the Missouri statewide estimate closely. Both are climate-based estimates, so treat the edges as fuzzy, not exact.
Do dogs in Kansas City 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 Missouri are typically active mid-February to early December, a longer window than fleas get.
