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.
