Frequently asked questions
When does flea season start in Oklahoma City?
Around early 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 Oklahoma City different from the rest of Oklahoma?
Not meaningfully — Oklahoma City tracks the Oklahoma statewide estimate closely. Both are climate-based estimates, so treat the edges as fuzzy, not exact.
Do dogs in Oklahoma 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 Oklahoma are typically active nearly year-round, with a brief midwinter lull, a longer window than fleas get.
