How can you kill fleas without hiring an exterminator?

Not really. The most effective way of getting rid of fleas is to use one of those once a month flea medications such as Frontline, Advantage or Advocate. The best, most effective brands can be bought from your vet. These are a once a month flea medication that will prevent fleas & ticks from getting on him or her for a month. You apply it topically. Combing the dog regularly will remove dead or dying fleas, and should be done until no more fleas can be seen. Washing the dog using a flea shampoo for dogs is also another method for helping getting rid of fleas. Never use human shampoo, detergent or any other products with strong chemicals in. They may kill the fleas, but will also irritate the dog's skin and will cause unnecessary discomfort.
