Parasitology paper

"Question 20: 10 marks

A client visits your clinic in desperate need of advice. He has attempted ti treat his dog's flea infestation using various "flea soaps" and powders, obtained at a local supermarket. Each product drastically reduced the number of fleas on the dog, but the dog becomes reinfested shortly after the treatment. There are fleas everywhere and are now attacking your client and his family members. Describe the life history of the flea to your client and explain to your client why the dog is becoming reinfested. Design a flea control program for this client. Make sure you address the three essentials of a successful flea control program (burning down the house is not an option)"
