Frequently asked questions

When does flea season start in Bangor?

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 Bangor different from the rest of Maine?

Not meaningfully — Bangor tracks the Maine statewide estimate closely. Both are climate-based estimates, so treat the edges as fuzzy, not exact.

Do dogs in Bangor 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 Maine are typically active early April to mid-November, a longer window than fleas get.
