When does flea season start in Georgia?
Flea season in Georgia typically runs late January to late December, with the heaviest pressure Apr–Oct. Outside that window outdoor fleas slow down — they don't disappear.
The Georgia flea picture
From Savannah's coastal humidity to Atlanta's shaded suburbs, Georgia hands fleas nearly twelve months of workable weather — the statewide average sits near 48°F even in January. Peak pressure locks in by April and doesn't ease until November arrives. The brief midwinter dip is no reason to pause meds: fleas already inside a warm Georgia home keep breeding straight through it, and vets recommend prevention without a break.
One thing that's true in every state: indoor fleas are year-round everywhere. A heated house in January is a fine flea nursery, which is why the calendar above describes outdoor pressure — not whether fleas are possible.

Frequently asked questions
When does flea season start in Georgia?
Around late January in a typical year, once average temperatures hold around 50°F — the point where fleas begin reproducing in earnest outdoors. Warm springs pull that earlier, which is a good argument for not waiting.
When does flea season end in Georgia?
Outdoor flea pressure typically fades around late December, when sustained cold shuts down reproduction outside. Indoors is another story — heated homes stay flea-friendly all winter.
Does my dog need flea prevention in winter in Georgia?
Yes — veterinary organizations recommend year-round prevention everywhere, Georgia included. Fleas overwinter indoors on pets and in bedding regardless of the weather outside, and a warm snap can restart outdoor activity early. The season calendar tells you when to be extra vigilant, not when to stop.
What about ticks in Georgia?
Ticks run on their own, earlier calendar — in Georgia that's year-round. See the Georgia tick season page for the month-by-month picture and the species involved.
