We did the whole house but I still feel little stings around my legs (no bites).
It is our recommendation and industry standard that you vacuum immediately before the application of Precor 2000 and every day or every other day after the application for the next two weeks. Vacuums can physically remove a decent percentage of flea eggs that are in the carpet, along with much of the organic crud that the flea larvae feed on. A critical part of the diet of the larva is dried blood, present there as fecal material from the fleas that are on the pets. Wherever the pets spend time they will shed the fecal matter and the eggs, so it is extremely important that you focus on these potential hot spots where the pets sleep. A vacuum also will remove a small percentage of larvae, but the larva is pretty tenacious, and will wrap around the carpet fibers down there at the base of the pile, and hold on for dear life as the vacuum passes by. The pupa is even tougher to physically remove, for it uses fibers as part of its "cocoon". But, the vacuum will stimulate the flea adults still in their pupa form to quickly emerge as the adult, and at this point perhaps be sucked up in the vacuum. Even if they are not removed by the vacuum, at least they now are exposed and susceptible to your treatment. After two weeks most infestations require that you do a second application of the Precor 2000 and continue with the vacuuming.
