How Common Are Fleas in Colorado?

Although there are more than 80 species of fleas in Colorado, flea problems on pets are not as prevalent as they are in other states. This is largely because Colorado’s dry climate is unsuitable for the growth of immature fleas. In addition, only certain species are responsible for biting humans. These tiny, reddish-brown insects are blood-suckers, which means that they have specialized mouth parts for piercing the skin.

The most common flea in Colorado is the human flea, also known as Pulex irritans. It lives on both humans and animals and is associated with wild mammals. Because of this, fleas in Colorado are most likely to be picked up from animals that have recently abandoned their dens. Dogs and cats are the most common hosts of fleas, but humans can contract fleas through pets brought from other parts of the country.

Although most fleas are not harmful to humans, plague is potentially life-threatening for humans. Colorado has had 45 confirmed cases of plague between 1957 and 1999. Fortunately, this plague-causing bacterium can be treated with antibiotics. But it is still important to be vigilant when around animals to protect yourself and your pets.

Ticks can also infect people and pets. Ticks are common in Colorado, although they are less common than in other states. Whether your pet is outdoors or indoors, you should protect them with a monthly or annual parasite prevention plan.
