Treating for fleas is not an easy task. For the home owner who is considering doing it themselves then I would suggest the following. First thing you want to do is get the pet treated by frontline and a good flea powder or dip. Leave the treated pet outside in the yard and then go inside and vacuum like crazy. Pick everything up off of the floor and vacuum under the beds, in closets, on stairs, under tables, under the furniture, the bathroom, the basement. Vacuum over the areas you vacuumed. This step is very important. Then throw the bag away outside. Now you need to pick a product to treat with. I suggest that the product you choose have an insect growth regulator in it or an IGR. The most common is methoporene. If the product says it has an IGR in it then it is ok. Then treat thoroughly. You want to cover as much area as possible. A good fan spray on the carpets and especially paying attention to the pets bedding area and hang outs. Stairs and the floor in front of sofas and things like that are hot spots because the pets usually jump off of these items and they plop down the stairs where the flea eggs fall off. A word of caution about foggers. If you decide to fog then pay attention to see if it has an IGR added to the fogger. If not then you are wasting your money. Buy enough foggers to cover all the areas and rooms. Use caution because the foggers are explosive and can blow your house up! When I was treating house I would advise the customer to shut off the main gas main to cut off all possible open flames that might be present in the stove or heaters. Read the label of any chemical you use as it will have direction and cautions to follow. Precor is a good product that is used and comes as ready to use spray and as a concentrate. For the next few vacuums you will need to toss the bag. Also, don't be alarmed to see a flurry of new activity a week or so later as the eggs start hatching. This activity will subside quickly and is not a problem to worry about.
