Didn't your vet give Daisy anything for the itching? Some animals can have an allergic reaction to flea bites which causes alot of scratching.

Also if you have alot of flea dirt (flea poop) that means you have more than one flea. I posted some information on flea life cycles below. If you are using the Frontline PLUS every month then you really don't need to do anything else except vacuume and wash pet bedding, as Frontline PLUS not only kills adult fleas on the animal BEFORE they bite, but also breaks the life cycle of reproduction in your house. The PLUS part of the ingredient is carried down to carpets, crevices etc. when your Frontline treated pet sheds hair and dandruff, and we all know how pet hair/dandruff seem to get everywhere. lol



Flea Life Cycle

Understanding the life cycle of the flea is necessary in order to control it. The flea has several stages to its life cycle. Adult fleas spend most of their time on the dog or cat - they must be dislodged to leave since they will not do so voluntarily. Despite this, when the flea population on the dog becomes excessive humans tend to be an acceptable alternative to the flea. The average life span of an adult flea is probably about 6 weeks - but fleas can live as long as a year under certain conditions. A female flea can lay 20 to 28 eggs a day. She may lay several hundred eggs over her life span. These eggs fall off the pet and develop where they land. They are small and can even develop in the cracks in wood floors or other small crevices. A larvae hatches from the flea egg. It takes as few as 9 days to as long as 200 days to go through its growth stages. At this time is forms a pupae and waits for the right time to hatch. It is estimated that for every adult flea found on the pet, there are about 10 developing fleas in the pet's environment.



Flea Larvae

Flea eggs hatch into worm-like larvae which move away from light and downwards. This means that they are usually found deep in the carpet pile. They tend to accumulate in areas where the pet rests, but have been observed to crawl as far as 20 feet while in this stage of the life cycle.


Whilst larvae are susceptible to household flea insecticides, they only account for 35% of a typical infestation. And because they are so small, and tend to move into hard-to-get areas, it is just about impossible to know whether you've managed to spray them all.


Once again, the lesson is that flea prevention is better than cure. In other words, far better to treat your pet with a product that stops flea reproduction before it happens, than end up trying to chase possibly hundreds of larvae around the house.
