Traditionally, we think of “flea season” as being the summer months, but in actuality, fleas pose a danger nearly year around in some parts of the United States. Fleas do like warm temperatures and higher humidity, but it’s not safe to assume that fleas won’t show up until June, or that once autumn is here fleas will no longer be a problem. Fleas can breed as long as the temperature is 60 degrees or warmer, and their larvae will hatch if the humidity is at least 50% or greater.
In dryer, cooler climates the flea season may be abbreviated somewhat, but even in (for instance) Montana, fleas will remain active from April through November. In the Midwest, flea season is from March through December and in the South and West Coasts, it extends throughout the entire year.
This leaves very little, if any, break from vigilance and preventative activities. The map depicted below from Weather.com shows the typical seasonal flea activity in the U.S.
So, when should we begin routine flea treatments for our pets? Obviously, that varies from region to region and depends on the situation, but many sources recommend beginning treatment a few weeks prior to the beginning of flea season in your area and continuing on through the end of it. For most areas of the country, this will mean treating nearly every month of the year, with at the most a few months break. Consult your veterinarian to see what he or she recommends.
If you’re considering a flea and tick treatment for your pet, it’s important to be advised of safety concerns being raised about some over the counter supermarket brands, and to be sure you’re using the products strictly according to directions. Again, your vet is the best source of guidance on what to use, when and how to use it.
