The flea that primarily attacks the dog is called the cat flea. This flea attacks dogs, cats, and several other wild hosts including rodents, rabbits, squirrels, skunks and yes, the opossum. They will also attack humans as well.  As you treat your yard, your dog, and your house you need to realize that these other animals can re-infest your yard.  

A flea can go from the egg stage to the adult stage in anywhere from a few weeks to several months (even over 1 year).  This life cycle helps ensure their survival.  If conditions are not right for the adult flea, the flea will wait in the pupae stage, to emerge as an adult until the conditions are favorable for the survival of the adult.  

The flea lays eggs on its host.  These eggs are not attached to the host so they are constantly falling off.  When a dog gets up from a nap and shakes, the dog is shaking the eggs off of his body.  The egg then becomes a larva.  

The larva can live on the dog or larva also live under grass, soil, mulch or other organic matter.  Larva are very susceptible to heat and desiccation so they usually stay in shady moist areas of the yard.  Treating your flower beds is very important. You may see the adults out in the middle of your yard, but they are coming from your mulch beds where it is shady and moist.  

After the larva stage, the flea develops into a pupae. This pupae stage is what makes the flea so hard to control. The pupae is made out of a silk like cocoon that protects the flea.  This cocoon is very sticky when first developed and dust and other debris stick to it making it very hard to detect. If someone moves out of an apartment that had a dog with fleas, the apartment could be closed for months. When the new tenants open the door and walk in, the adult flea will emerge from the pupae stage and begin biting the person who has entered.  These pupae respond to vibration.  That is why you hear people talk about vacuuming when trying to control fleas.  Vacuuming removes fleas and the vibration from the vacuuming brings the flea out of the pupae stage and into the adult stage.  

All these factors make the flea very hard to control.  When using control products there are several different products to use.  Some products are used inside, some outside and some on the animal.  A pest management professional is always a good option when dealing with fleas. Next week I will write about several different control products. In the mean time wash your animal with a flea shampoo, spray the dog with Petcor, use Ultracide inside the house, spread Lebanon Insect Control in the yard and spray the yard with Nylar IGR.  

Since it takes about two weeks to control fleas, it will also take me two weeks to write about controlling fleas.
