Frequently asked questions
When does flea season start in Coeur d'Alene?
Around late 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.
Is flea season in Coeur d'Alene different from the rest of Idaho?
Not meaningfully — Coeur d'Alene tracks the Idaho statewide estimate closely. Both are climate-based estimates, so treat the edges as fuzzy, not exact.
Do dogs in Coeur d'Alene 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 Idaho are typically active early March to mid-November, a longer window than fleas get.
