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.
