Frequently asked questions

When does flea season start in Norfolk?

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 Norfolk different from the rest of Virginia?

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

Do dogs in Norfolk 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 Virginia are typically active year-round, a longer window than fleas get.
