Frequently asked questions

When does flea season start in New Orleans?

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

Is flea season in New Orleans different from the rest of Louisiana?

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

Do dogs in New Orleans 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.
