Preventing fleas from living and breeding in and around your house will help keep your kitty from being infested with them and bringing them inside.
Things to Consider:
Protect the Exterior – You should use a lawn spray on the areas immediately surrounding the exterior of your house.
Protect Kitty from Fogger – A fogger is a very effective tool to eradicate fleas inside your home. If you plan to use a fogger, you should consider keeping your cat out of the house for a few of days, to ensure that he doesn´t get sick from the fogger´s chemicals.
Use a Carpet Rake – When using carpet flea powder, you should use a carpet rake, or something similar like a push broom, to work the powder down into the carpet. Also, you need to remember that many carpet powders don´t kill adult fleas, only the eggs and larvae that may be in the fibers of the carpet.
