Fleas are gross, annoying, and potentially harmful to your pet’s health. They are also quite fascinating. Fleas are very real threats to your pet. They love your pets. They live for your pets. In fact, if they choose your pets as a host, they can’t live without them. Once a flea has access to your pets’ bodies, they’ll be inseparable. Fleas will start reproducing. Before you know it, you’ll have a flea infestation in your home.

Have no doubts—fleas are your enemies and knowing your enemy is the best way to control them. Below are some strange, informative and disconcerting facts about these little creeps.

The good news is that science has made tremendous strides to prevent and, when necessary, eradicate flea problems the past twenty years. These flea control protocols are much safer and less expensive then old procedures – dips, environmental foggers, etc… The key is to address all four stages of the flea life cycle: egg, larvae, pupae, and adult.
