Frequently asked questions

When does flea season start in Austin?

It never fully stops — Austin's monthly averages support flea activity essentially all year, with the heaviest stretch Mar–Nov.

Is flea season in Austin different from the rest of Texas?

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

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