Frequently asked questions

When does flea season start in Baton Rouge?

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

Is flea season in Baton Rouge different from the rest of Louisiana?

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

Do dogs in Baton Rouge 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 Louisiana are typically active year-round, a longer window than fleas get.
