Fleas can survive in a dormant state under the right conditions in cold weather, meaning if they aren’t actively bothering you or your dog during the winter they may still be present, waiting for the right opportunity.  They love temperatures between 65 – 80 degrees, however they’ll make due in any temperatures.  They can remain dormant for up to 30 weeks, while freezing temps will kill exposed fleas, those that are tucked away in nests, your home or even your pets will wait until the right temperatures to emerge.  


Even if your dog or cat spends minimal or no time outside, you still should practice flea prevention because you can be a flea’s entry into your home and onto your pet. If home is in a warm weather climate, you should consider year round flea control; for cooler climates that experience freezing temperatures, initiate flea prevention in the spring, before they come out of  the dormant stage.  Flea treatments vary depending on what stage of development they are in. Some kill adult fleas only while others leave the adults alone but prevent egg hatching to break the life cycle.  

The bottom line: Fleas are year round in one form or another.
