Don't be lulled into a false sense of security that fleas are a thing of the past. Even with the advances in fleas control, fleas are out in full force. The wet winter we had in Laguna Beach has helped to set up the prime conditions for a flea and tick population explosion. This is a once a month oral drug that controls flea population by rendering biting fleas effectively sterile. This revolutionized flea control because it meant that we didn't have to put chemicals in our carpets to stop the flea life cycle.
Fleas can be difficult to kill.
There are four different stages of the flea life cycle. The first and second are the egg and larva. Next comes the pupa and the adult. The egg and pupa are virtually impossible to kill. The vulnerable stage is the larvae.
