What flea fogger works well?

You can get some results from a fogger, but you can never get it concentrated enough to kill all the fleas unless the area is extremely small. Fogs also have no residual, so after it airs out-it's gone. They like to go down to the base of your carpet fibers, under furniture, cushions, etc. which is why pros don't fog only for fleas, they pretty much spray everything. I recommend an aerosol Precor 2000 which can be used to treat small areas by a homeowner and it contains what most pros use. You have to do something with any host animals that go in and out to keep them from bringing in more fleas later and vacuum frequently, discarding the bag or storing vac outside until after fleas are gone and bag disposed of for good.

No insecticide kills the pupal stage so they will still emerge into the chemical even if treatment is effective for up to 2 weeks, but if you treated everything they should also die. Vibration stimulates them to emerge and contact the residual chemical so frequent vacuuming helps speed it along.
