Frequently asked questions

When does flea season start in Chattanooga?

Around late February 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 Chattanooga different from the rest of Tennessee?

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

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