Fleas are a real annoying insect to get rid of. You will need to get a flea bath or flea dip for the infested pet and follow the directions on using this on your pet. Then as soon as the bath is done you want to apply a preventative like frontline to the animal this lasts 3 months and prevents fleas ,ticks and other pests from bothering your animal. You will also need to be sure to get a flea dust for your carpet and sprinkle this powder on all your carpet and follow the directions for when you vacuum. It is important to be very thorough and also be sure to throw away your vacuum bag outside as soon as you vacuum so they do not live in the bag and re infest your home.
