High Flea And Tick Affected Regions In USA

To get a fair idea as to what preventatives work best for the part of US you live in will significantly help you deal with these parasites.

Fleas and tick pose major problems in US regions with a warm and humid climate. Their population blows out due to high temperatures and increased humidity in some parts of the country. In others that have mild and colder temperatures, the frequency is less but not negligible. Pets in the US are thus not safe enough as the ticks and fleas have spread their reach in all the 50 states leaving no scope for escape. Most of the cases prevail throughout the year because the flea and tick population replicates persistently unless the pet is not on preventatives. So, to get a fair idea as to what preventatives work best for the part of US you live in will significantly help you deal with these parasites.

Northwest regions like Washington, Oregon, and Northern California are generally high on humidity and are mostly precipitating. However, there are some drier parts that have a mild climate and are apt for fleas to multiply. Other than that, ticks that thrive in this region generally include – Western black-legged tick, American Dog tick, and Rocky Mountain Tick. Thus, pets in this region are highly vulnerable to flea infestation and tick-borne diseases like Rocky Mountain Spotted Fever and need a preventative that is waterproof.

Southwest Region

This region includes Arizona, Southern California and New Mexico that mostly have a desert climate – dry and arid. Because the climate is normally hot, fleas are a big problem here. They cause bubonic plagues, tapeworm infections and flea allergy dermatitis in pets making it hard for pet owners to combat them. Though fortunately, ticks are less in this region compared to other areas of the USA, the risk cannot be completely negated as their presence can still cause tick-borne diseases even with a small population.
