Cat Fleas vs Dog Fleas

When considering the difference between cat fleas vs dog fleas, many people believe that all dogs have dog fleas and all cats have cat fleas.

Although it seems logical, it's actually a common misconception.  In fact, about 95 percent of all fleas in the United States that infect your pet are actually cat fleas....known by the scientific name Ctenocephalides felis.  

The dog flea, known by the scientific name Ctenocephalides canis, is similar in appearance to the cat flea but they're much less common.

So....now that we've determined which type of flea your pet has, the next course of action is to determine where the fleas came from.

Chances are your dog or cat picked up the fleas from your yard, or they were exposed to another pet or household that had fleas.  

Since many other animals such as rabbits, raccoons, fox and opossums can carry fleas, they often drop eggs into your lawn that soon develop into larvae that feed on organic material within your yard.  

The larvae then spins a cocoon that protects it until it emerges as an adult flea looking for a host to feed on.  Then as your dog or cat goes outside they're unknowingly exposed.

"Flea season" typically occurs in the late spring and early summer as the outside temperature and humidity begins to rise and the foliage thickens on nearby trees and shrubs.  These conditions create the ideal environment for growth.

Removing Fleas From Your Yard

Since flea larvae need moist conditions to survive, removing low hanging branches and mowing your lawn will allow sunlight to dry out these damp conditions and disrupt the fleas lifecycle.

Start by trimming the long weeds and grass around fence lines, outdoor furniture, buildings and especially your doghouse if you have one.  Areas where your pet spends most of its time outdoors will also be a hot spot for fleas, so pay special attention to these areas. 

Rake up and bag piles of cut grass, pick up children's toys and remove any brush piles you have around your lawn.  Eliminating these damp, shady hiding spots is essential in controlling fleas in your yard.

Cedar Wood Chips

Cedar is a natural repellent for fleas.  Although it's not practical to throw cedar wood chips throughout your entire lawn, you can use them to line the area around compost piles, fences, and around your home.

Beneficial Nematodes

Spraying beneficial nematodes in your lawn is a safe, non-toxic way to effectively kill fleas in your yard.  Nematodes are microscopic roundworms that feed on organic matter as well as insects and fleas.
